How to modify a word doc with Python? [duplicate] - python

The oodocx module mentioned in the same page refers the user to an /examples folder that does not seem to be there.
I have read the documentation of python-docx 0.7.2, plus everything I could find in Stackoverflow on the subject, so please believe that I have done my “homework”.
Python is the only language I know (beginner+, maybe intermediate), so please do not assume any knowledge of C, Unix, xml, etc.
Task : Open a ms-word 2007+ document with a single line of text in it (to keep things simple) and replace any “key” word in Dictionary that occurs in that line of text with its dictionary value. Then close the document keeping everything else the same.
Line of text (for example) “We shall linger in the chambers of the sea.”
from docx import Document
document = Document('/Users/umityalcin/Desktop/Test.docx')
Dictionary = {‘sea’: “ocean”}
sections = document.sections
for section in sections:
print(section.start_type)
#Now, I would like to navigate, focus on, get to, whatever to the section that has my
#single line of text and execute a find/replace using the dictionary above.
#then save the document in the usual way.
document.save('/Users/umityalcin/Desktop/Test.docx')
I am not seeing anything in the documentation that allows me to do this—maybe it is there but I don’t get it because everything is not spelled-out at my level.
I have followed other suggestions on this site and have tried to use earlier versions of the module (https://github.com/mikemaccana/python-docx) that is supposed to have "methods like replace, advReplace" as follows: I open the source-code in the python interpreter, and add the following at the end (this is to avoid clashes with the already installed version 0.7.2):
document = opendocx('/Users/umityalcin/Desktop/Test.docx')
words = document.xpath('//w:r', namespaces=document.nsmap)
for word in words:
if word in Dictionary.keys():
print "found it", Dictionary[word]
document = replace(document, word, Dictionary[word])
savedocx(document, coreprops, appprops, contenttypes, websettings,
wordrelationships, output, imagefiledict=None)
Running this produces the following error message:
NameError: name 'coreprops' is not defined
Maybe I am trying to do something that cannot be done—but I would appreciate your help if I am missing something simple.
If this matters, I am using the 64 bit version of Enthought's Canopy on OSX 10.9.3

UPDATE: There are a couple of paragraph-level functions that do a good job of this and can be found on the GitHub site for python-docx.
This one will replace a regex-match with a replacement str. The replacement string will appear formatted the same as the first character of the matched string.
This one will isolate a run such that some formatting can be applied to that word or phrase, like highlighting each occurence of "foobar" in the text or perhaps making it bold or appear in a larger font.
The current version of python-docx does not have a search() function or a replace() function. These are requested fairly frequently, but an implementation for the general case is quite tricky and it hasn't risen to the top of the backlog yet.
Several folks have had success though, getting done what they need, using the facilities already present. Here's an example. It has nothing to do with sections by the way :)
for paragraph in document.paragraphs:
if 'sea' in paragraph.text:
print paragraph.text
paragraph.text = 'new text containing ocean'
To search in Tables as well, you would need to use something like:
for table in document.tables:
for row in table.rows:
for cell in row.cells:
for paragraph in cell.paragraphs:
if 'sea' in paragraph.text:
paragraph.text = paragraph.text.replace("sea", "ocean")
If you pursue this path, you'll probably discover pretty quickly what the complexities are. If you replace the entire text of a paragraph, that will remove any character-level formatting, like a word or phrase in bold or italic.
By the way, the code from #wnnmaw's answer is for the legacy version of python-docx and won't work at all with versions after 0.3.0.

I needed something to replace regular expressions in docx.
I took scannys answer.
To handle style I've used answer from:
Python docx Replace string in paragraph while keeping style
added recursive call to handle nested tables.
and came up with something like this:
import re
from docx import Document
def docx_replace_regex(doc_obj, regex , replace):
for p in doc_obj.paragraphs:
if regex.search(p.text):
inline = p.runs
# Loop added to work with runs (strings with same style)
for i in range(len(inline)):
if regex.search(inline[i].text):
text = regex.sub(replace, inline[i].text)
inline[i].text = text
for table in doc_obj.tables:
for row in table.rows:
for cell in row.cells:
docx_replace_regex(cell, regex , replace)
regex1 = re.compile(r"your regex")
replace1 = r"your replace string"
filename = "test.docx"
doc = Document(filename)
docx_replace_regex(doc, regex1 , replace1)
doc.save('result1.docx')
To iterate over dictionary:
for word, replacement in dictionary.items():
word_re=re.compile(word)
docx_replace_regex(doc, word_re , replacement)
Note that this solution will replace regex only if whole regex has same style in document.
Also if text is edited after saving same style text might be in separate runs.
For example if you open document that has "testabcd" string and you change it to "test1abcd" and save, even dough its the same style there are 3 separate runs "test", "1", and "abcd", in this case replacement of test1 won't work.
This is for tracking changes in the document. To marge it to one run, in Word you need to go to "Options", "Trust Center" and in "Privacy Options" unthick "Store random numbers to improve combine accuracy" and save the document.

Sharing a small script I wrote - helps me generating legal .docx contracts with variables while preserving the original style.
pip install python-docx
Example:
from docx import Document
import os
def main():
template_file_path = 'employment_agreement_template.docx'
output_file_path = 'result.docx'
variables = {
"${EMPLOEE_NAME}": "Example Name",
"${EMPLOEE_TITLE}": "Software Engineer",
"${EMPLOEE_ID}": "302929393",
"${EMPLOEE_ADDRESS}": "דרך השלום מנחם בגין דוגמא",
"${EMPLOEE_PHONE}": "+972-5056000000",
"${EMPLOEE_EMAIL}": "example#example.com",
"${START_DATE}": "03 Jan, 2021",
"${SALARY}": "10,000",
"${SALARY_30}": "3,000",
"${SALARY_70}": "7,000",
}
template_document = Document(template_file_path)
for variable_key, variable_value in variables.items():
for paragraph in template_document.paragraphs:
replace_text_in_paragraph(paragraph, variable_key, variable_value)
for table in template_document.tables:
for col in table.columns:
for cell in col.cells:
for paragraph in cell.paragraphs:
replace_text_in_paragraph(paragraph, variable_key, variable_value)
template_document.save(output_file_path)
def replace_text_in_paragraph(paragraph, key, value):
if key in paragraph.text:
inline = paragraph.runs
for item in inline:
if key in item.text:
item.text = item.text.replace(key, value)
if __name__ == '__main__':
main()

I got much help from answers from the earlier, but for me, the below code functions as the simple find and replace function in word would do. Hope this helps.
#!pip install python-docx
#start from here if python-docx is installed
from docx import Document
#open the document
doc=Document('./test.docx')
Dictionary = {"sea": "ocean", "find_this_text":"new_text"}
for i in Dictionary:
for p in doc.paragraphs:
if p.text.find(i)>=0:
p.text=p.text.replace(i,Dictionary[i])
#save changed document
doc.save('./test.docx')
The above solution has limitations. 1) The paragraph containing The "find_this_text" will became plain text without any format, 2) context controls that are in the same paragraph with the "find_this_text" will be deleted, and 3) the "find_this_text" in either context controls or tables will not be changed.

For the table case, I had to modify #scanny's answer to:
for table in doc.tables:
for col in table.columns:
for cell in col.cells:
for p in cell.paragraphs:
to make it work. Indeed, this does not seem to work with the current state of the API:
for table in document.tables:
for cell in table.cells:
Same problem with the code from here: https://github.com/python-openxml/python-docx/issues/30#issuecomment-38658149

The Office Dev Centre has an entry in which a developer has published (MIT licenced at this time) a description of a couple of algorithms that appear to suggest a solution for this (albeit in C#, and require porting):" MS Dev Centre posting

The library python-docx-template is pretty useful for this. It's perfect to edit Word documents and save them back to .docx format.

The problem with your second attempt is that you haven't defined the parameters that savedocx needs. You need to do something like this before you save:
relationships = docx.relationshiplist()
title = "Document Title"
subject = "Document Subject"
creator = "Document Creator"
keywords = []
coreprops = docx.coreproperties(title=title, subject=subject, creator=creator,
keywords=keywords)
app = docx.appproperties()
content = docx.contenttypes()
web = docx.websettings()
word = docx.wordrelationships(relationships)
output = r"path\to\where\you\want\to\save"

he changed the API in docx py again...

As shared by some of the fellow users above that one of the challenges is finding and replacing text in word document is retaining styles if the word spans across multiple runs this could happen if word has many styles or if the word was edited multiple times when the document was created. So a simple code which assumes a word would be found completely within a single run is generally not true so python-docx based code shared above may not work for many many scenarios.
You can try the following API
https://rapidapi.com/more.sense.tech#gmail.com/api/document-filter1
This has generic code to deal with the scenarios. The API currently only addresses the paragraphic text and tabular text is currently not supported and I will try that soon.

import docx2txt as d2t
from docx import Document
from docx.text.paragraph import Paragraph
document = Document()
all_text = d2t.process("mydata.docx")
# print(all_text)
words=["hey","wow"]
for i in range words:
all_text=all_text.replace(i,"your word variable")
document.add_paragraph(updated + "\n")
print(all_text)
document.save('data.docx')

How do you insert an image into a specific location in an existing Word document with Python?

What I want to do is insert an image into a specific location in an existing Word document using Python. I've looked at various libraries to do this; I'm using the docx-mailmerge package to insert text and tables using Word merge fields, but unfortunately image merging is just a TODO/wishlist feature. python-docx meanwhile allows image insertion, but only at the end of a document, not in specific places.
Is there another library that does this, or a good trick to accomplish it?
Fiddling around with the underlying API (and thanks to this SO answer) I hacked my way to success:
add a placeholder in your Word document where the image should go, something like a single line that says [ChartImage1]
find the paragraph object in the document that contains that text
replace the text of that paragraph with an empty string
add a run, and inside that add your image
So something like:
document = Document("template.docx")
image_paras = [i for i, p in enumerate(document.paragraphs) if "[ChartImage1]" in p.text]
p = document.paragraphs[image_paras[0]]
p.text = ""
r = p.add_run()
r.add_picture("path/to/image.png")
document.save("my_doc.docx")

Adding Image at the very beginning of an already existing docx document [duplicate]

I use Python-docx to generate Microsoft Word document.The user want that when he write for eg: "Good Morning every body,This is my %(profile_img)s do you like it?"
in a HTML field, i create a word document and i recuper the picture of the user from the database and i replace the key word %(profile_img)s by the picture of the user NOT at the END OF THE DOCUMENT. With Python-docx we use this instruction to add a picture:
document.add_picture('profile_img.png', width=Inches(1.25))
The picture is added to the document but the problem that it is added at the end of the document.
Is it impossible to add a picture in a specific position in a microsoft word document with python? I've not found any answers to this in the net but have seen people asking the same elsewhere with no solution.
Thanks (note: I'm not a hugely experiance programmer and other than this awkward part the rest of my code will very basic)
Quoting the python-docx documentation:
The Document.add_picture() method adds a specified picture to the end of the document in a paragraph of its own. However, by digging a little deeper into the API you can place text on either side of the picture in its paragraph, or both.
When we "dig a little deeper", we discover the Run.add_picture() API.
Here is an example of its use:
from docx import Document
from docx.shared import Inches
document = Document()
p = document.add_paragraph()
r = p.add_run()
r.add_text('Good Morning every body,This is my ')
r.add_picture('/tmp/foo.jpg')
r.add_text(' do you like it?')
document.save('demo.docx')
well, I don't know if this will apply to you but here is what I've done to set an image in a specific spot to a docx document:
I created a base docx document (template document). In this file, I've inserted some tables without borders, to be used as placeholders for images. When creating the document, first I open the template, and update the file creating the images inside the tables. So the code itself is not much different from your original code, the only difference is that I'm creating the paragraph and image inside a specific table.
from docx import Document
from docx.shared import Inches
doc = Document('addImage.docx')
tables = doc.tables
p = tables[0].rows[0].cells[0].add_paragraph()
r = p.add_run()
r.add_picture('resized.png',width=Inches(4.0), height=Inches(.7))
p = tables[1].rows[0].cells[0].add_paragraph()
r = p.add_run()
r.add_picture('teste.png',width=Inches(4.0), height=Inches(.7))
doc.save('addImage.docx')
Here's my solution. It has the advantage on the first proposition that it surrounds the picture with a title (with style Header 1) and a section for additional comments. Note that you have to do the insertions in the reverse order they appear in the Word document.
This snippet is particularly useful if you want to programmatically insert pictures in an existing document.
from docx import Document
from docx.shared import Inches
# ------- initial code -------
document = Document()
p = document.add_paragraph()
r = p.add_run()
r.add_text('Good Morning every body,This is my ')
picPath = 'D:/Development/Python/aa.png'
r.add_picture(picPath)
r.add_text(' do you like it?')
document.save('demo.docx')
# ------- improved code -------
document = Document()
p = document.add_paragraph('Picture bullet section', 'List Bullet')
p = p.insert_paragraph_before('')
r = p.add_run()
r.add_picture(picPath)
p = p.insert_paragraph_before('My picture title', 'Heading 1')
document.save('demo_better.docx')
This is adopting the answer written by Robᵩ while considering more flexible input from user.
My assumption is that the HTML field mentioned by Kais Dkhili (orignal enquirer) is already loaded in docx.Document(). So...
Identify where is the related HTML text in the document.
import re
## regex module
img_tag = re.compile(r'%\(profile_img\)s') # declare pattern
for _p in enumerate(document.paragraphs):
if bool(img_tag.match(_p.text)):
img_paragraph = _p
# if and only if; suggesting img_paragraph a list and
# use append method instead for full document search
break # lose the break if want full document search
Replace desired image into placeholder identified as img_tag = '%(profile_img)s'
The following code is after considering the text contains only a single run
May be changed accordingly if condition otherwise
temp_text = img_tag.split(img_paragraph.text)
img_paragraph.runs[0].text = temp_text[0]
_r = img_paragraph.add_run()
_r.add_picture('profile_img.png', width = Inches(1.25))
img_paragraph.add_run(temp_text[1])
and done. document.save() it if finalised.
In case you are wondering what to expect from the temp_text...
[In]
img_tag.split(img_paragraph.text)
[Out]
['This is my ', ' do you like it?']
I spend few hours in it. If you need to add images to a template doc file using python, the best solution is to use python-docx-template library.
Documentation is available here
Examples available in here
This is variation on a theme. Letting I be the paragraph number in the specific document then:
p = doc.paragraphs[I].insert_paragraph_before('\n')
p.add_run().add_picture('Fig01.png', width=Cm(15))

I can't change the style of text in Word documents with Python-docx

I created a word document which contains the text
Hello. You owe me ${debt}. Please pay me back soon.
in Times New Roman size 12. The file name is debtTemplate.docx. I would like to replace {debt} by an actual number (1.20) using python-docx. I tried that following code:
from docx import Document
document = Document("debtTemplate.docx")
paragraphs = document.paragraphs
debt = "1.20"
paragraph = paragraphs[0]
text = paragraph.text
newText = text.format(debt=debt)
paragraph.clear()
paragraph.add_run(newText)
document.save("debt.docx")
This results in a new document with the desired text, but in Calabri font size 11. I would like the font to be like the original: Times New Roman size 12.
I know that you can add a style variable to paragraph.add_run(), so I tried that but nothing work. Eg paragraph.add_run(newText,style="Strong") didn't even change anything.
Does anyone know what I can do?
EDIT: here's a modified version of my code that I had hoped would work but didn't.
from docx import Document
document = Document("debtTemplate.docx")
document.save("debt.docx")
paragraphs = document.paragraphs
debt = "1.20"
paragraph = paragraphs[0]
style = paragraph.style
text = paragraph.text
newText = text.format(debt=debt)
paragraph.clear()
paragraph.add_run(newText,style)
document.save("debt.docx")
This page in the docs should help you understand why the style is not having an effect. It's a pretty easy fix: http://python-docx.readthedocs.org/en/latest/user/styles.html
I like a couple other things about what you've found though:
Using the str.format() method to do placeholder replacement is a nice, easy way to do lightweight text replacement. I'll have to add that to the documentation as an approach to simple custom document generation.
In the XML for a paragraph, there is an optional element called <w:defRPr> which Word uses to indicates the default formatting for any new text added to the paragraph, like if you started typing after placing your insertion point at the end of the paragraph. Right now, python-docx ignores that element. That's why you're getting the default Calibri 11 instead of the Times New Roman 12 you started with. But a useful feature might be to use that element, if present, to assign run properties to any new runs added at the end of the paragraph. If you want to add that as a feature request to the GitHub tracker we'll take a look at getting it implemented.

Python: Copy content from one word document to another word document and keeping format?

As the title says I would like to know if there is any module that will allow me to parse content from one Microsoft word document to another via python and keeping the format.
I want to read table data and transfer it to another table in another document.
Both doc A and B exist. I just want to be able to walk through the cells in both docs (not necessarily at the same time) and copy content without having to worry about if the text is formatted (font, italic, bold) or contains bullets.
I'm asking for python since it's my favorite language...
Following Kasra advice to use python-docx :
Rough example code.
Query document for table:
from docx import *
document = opendocx('xxxzzz.docx')
table = document.xpath('/w:document/w:body/w:tbl', namespaces=nsprefixes)[0]
Writing to another document:
output = opendocx('yyywwww.docx')
body = output.xpath('/w:document/w:body', namespaces=nsprefixes)[0]
body.append(table)
output.save('new-file-name.docx')

What stronger alternatives are there to difflib?

I am working on script that needs to be able to track revisions. The general idea is to give it a list of tuples where the first entry is the name of a field (ie "title" or "description" etc.), the second entry is the first version of that field, and the third entry is the revised version. So something like this:
[("Title", "The first version of the title", "The second version of the title")]
Now, using python docx I want my script to create a word file that will show the original version, and the new version with the changes bolded. Example:
Original Title:
This is the first version of the title
Revised Title:
This is the second version of the title
The way that this is done in python docx is to create a list of tuples, where the first entry is the text, and the second one is the formatting. So the way to create the revised title would be this:
paratext = [("This is the ", ''),("second",'b'),(" version of the title",'')]
Having recent discovered difflib I figured this would be a pretty easy task. And indeed, for simple word replacements such as sample above, it is, and can be done with the following function:
def revFinder(str1,str2):
s = difflib.SequenceMatcher(None, str1, str2)
matches = s.get_matching_blocks()[:-1]
paratext = []
for i in range(len(matches)):
print "------"
print str1[matches[i][0]:matches[i][0]+matches[i][2]]
print str2[matches[i][1]:matches[i][1]+matches[i][2]]
paratext.append((str2[matches[i][1]:matches[i][1]+matches[i][2]],''))
if i != len(matches)-1:
print ""
print str1[matches[i][0]+matches[i][2]:matches[i+1][0]]
print str2[matches[i][1]+matches[i][2]:matches[i+1][1]]
if len(str2[matches[i][1]+matches[i][2]:matches[i+1][1]]) > len(str1[matches[i][0]+matches[i][2]:matches[i+1][0]]):
paratext.append((str2[matches[i][1]+matches[i][2]:matches[i+1][1]],'bu'))
else:
paratext.append((str1[matches[i][0]+matches[i][2]:matches[i+1][0]],'bu'))
return paratext
The problems come when I want to do anything else. For example, changing 'teh' to 'the' produces t h e h (without the spaces, I couldn't figure out the formatting). Another issue is that extra text appended to the end is not shown as a change (or at all).
So, my question to all of you is what alternatives are there to difflib which are powerful enough to handle more complicated text comparions, or, how can I use difflib better such that it works for what I want? Thanks in advance
