Suppose I have an excel file excel_file.xlsx and i want to send it to my printer using Python so I use:
import os
os.startfile('path/to/file','print')
My problem is that this only prints the first sheet of the excel workbook but i want all the sheets printed. Is there any way to print the entire workbook?
Also, I used Openpyxl to create the file, but it doesn't seem to have any option to select the number of sheets for printing.
Any help would be greatly appreciated.
from xlrd import open_workbook
from openpyxl.reader.excel import load_workbook
import os
import shutil
path_to_workbook = "/Users/username/path/sheet.xlsx"
worksheets_folder = "/Users/username/path/worksheets/"
workbook = open_workbook(path_to_workbook)
def main():
all_sheet_names = []
for s in workbook.sheets():
all_sheet_names.append(s.name)
for sheet in workbook.sheets():
if not os.path.exists("worksheets"):
os.makedirs("worksheets")
working_sheet = sheet.name
path_to_new_workbook = worksheets_folder + '{}.xlsx'.format(sheet.name)
shutil.copyfile(path_to_workbook, path_to_new_workbook)
nwb = load_workbook(path_to_new_workbook)
print "working_sheet = " + working_sheet
for name in all_sheet_names:
if name != working_sheet:
nwb.remove_sheet(nwb.get_sheet_by_name(name))
nwb.save(path_to_new_workbook)
ws_files = get_file_names(worksheets_folder, ".xlsx")
# Uncomment print command
for f in xrange(0, len(ws_files)):
path_to_file = worksheets_folder + ws_files[f]
# os.startfile(path_to_file, 'print')
print 'PRINT: ' + path_to_file
# remove worksheets folder
shutil.rmtree(worksheets_folder)
def get_file_names(folder, extension):
names = []
for file_name in os.listdir(folder):
if file_name.endswith(extension):
names.append(file_name)
return names
if __name__ == '__main__':
main()
probably not the best approach, but it should work.
As a workaround you can create separate .xlsx files where each has only one spreadsheet and then print them with os.startfile(path_to_file, 'print')
I have had this issue(on windows) and it was solved by using pywin32 module and this code block(in line 5 you can specify the sheets you want to print.)
import win32com.client
o = win32com.client.Dispatch('Excel.Application')
o.visible = True
wb = o.Workbooks.Open('/Users/1/Desktop/Sample.xlsx')
ws = wb.Worksheets([1 ,2 ,3])
ws.printout()
you could embed vBa on open() command to print the excel file to a default printer using xlsxwriter's utility mentioned in this article:
PBPYthon's Embed vBA in Excel
Turns out, the problem was with Microsoft Excel,
os.startfile just sends the file to the system's default app used to open those file types. I just had to change the default to another app (WPS Office in my case) and the problem was solved.
Seems like you should be able to just loop through and change which page is active. I tried this and it did print out every sheet, BUT for whatever reason on the first print it grouped together two sheets, so it gave me one duplicate page for each workbook.
wb = op.load_workbook(filepath)
for sheet in wb.sheetnames:
sel_sheet = wb[sheet]
# find the max row and max column in the sheet
max_row = sel_sheet.max_row
max_column = sel_sheet.max_column
# identify the sheets that have some data in them
if (max_row > 1) & (max_column > 1):
# Creating new file for each sheet
sheet_names = wb.sheetnames
wb.active = sheet_names.index(sheet)
wb.save(filepath)
os.startfile(filepath, "print")

I want to loop over multiple files, creating new formulas for each file as I go. To do that I want to concatenate a string with a variable, then use excel wings create a new formula. To that end I've written this code:
file_name=r'[Element_IA_Gross.xlsx]'
equation=r'=SUM(\''+file_name+'Total Immediates\'!$R6:$T6)'
ws.range("O19").value= [equation]
If I print the variable equation I see what I want in the excel formula bar. However using the above code doesn't work? Any help much appreciated.
Thanks
The formula looks for the workbook in the default location so opens a file search window and waits for the input.
The following works based on why it worked for me by opening both workbooks, adding the formula to 'book1', save 'book1' and then close both books.
import xlwings as xw
file_name = 'Element_IA_Gross.xlsx'
workbook = 'Book1.xlsx'
with xw.App() as app:
wb1 = xw.Book(workbook)
wb2 = xw.Book(file_name)
ws = wb1.sheets('Sheet1')
equation = "=SUM('[" + file_name + "]Total Immediates'!$R6:$T6)"
ws["O19"].value = equation
wb1.save(workbook)
wb1.close()
wb2.close()
-------------Option 2 ----------
This option also worked including the whole path and filename in the formula.
import os
import xlwings as xw
path = r'F:\Projects\xlwings_test'
file_name = 'Element_IA_Gross.xlsx'
link = os.join(path, file_name)
workbook = 'Book1.xlsx'
with xw.App() as app:
wb1 = xw.Book(workbook)
ws = wb1.sheets('Sheet1')
equation = "SUM('[" + link + "]Total Immediates'!$R6:$T6)"
ws["O19"].value = equation
wb1.save(workbook)
wb1.close()
I've been trying to edit a .xslx worksheet using python and I have been successfully able to alter the cells value but when I use the save command from openpyxl, close the program, and open the excel spreadsheet, no changes have been saved. I have attached the code below and I would appreciate it if you could help me. I have tried reading other stackoverflow posts but when I try what they suggest it still doesn't work so I've turned to creating my first post here.
def editStock(choice, edit, stockSymbol):
sheet = setup()
stockRow = getStockRow(stockSymbol)
if choice == 7 or choice == 3 or choice == 2 or choice == 1:
print("Before")
print(sheet.cell(row = stockRow, column = choice).value)
sheet.cell(row = stockRow, column = choice).value = edit
print("After")
print(sheet.cell(row = stockRow, column = choice).value)
else:
sheet.cell(row = stockRow, column = choice).value = float(edit)
workbook = getWorkBook()
workbook.save(filename="Stocks.xlsx")
Here's my setup():
def setup():
directory = "C:\\Users\\shrey\\Desktop"
directory = directory.lower()
os.chdir(directory)
spreadname = "Stocks.xlsx"
workbook = openpyxl.load_workbook(spreadname)
sheet = workbook["Sheet1"]
return sheet
Here's my getWorkBook() for reference:
def getWorkBook():
directory = "C:\\Users\\shrey\\Desktop"
directory = directory.lower()
os.chdir(directory)
spreadname = "Stocks.xlsx"
workbook = openpyxl.load_workbook(spreadname)
return workbook
Here's my output when I call editStock():
Before
None
After
Dec-21-2021
And proof that it doesn't work: date is not altered
Sorry, the image is not very clear but the Dec-21-2021 should be right after the 'TSLA'
You should probably actually make a separate test script and share the whole thing, because you probably posted the methods that are working exactly correctly, and people typically will ask for that on stack overflow (I couldn't just grab your code and run it; that should usually be the case)
I wrote this little script to see what the matter was, and for me it worked fine.
But I noticed that there were two sheets called Sheet1. So make sure you are looking at the different sheets (the tabs). Once I figured that out, the data showed up just fine.
This code works when I run it, (including if the file already exists):
import os
import openpyxl
spreadname = "Stocks.xlsx"
sheetname = "THISONE"
if not os.path.exists(spreadname):
workbook = openpyxl.Workbook()
workbook.create_sheet(title=sheetname)
else:
workbook = openpyxl.load_workbook(spreadname)
sheet = workbook[sheetname]
c1 = sheet.cell(row=3, column=6)
c1.value = 123.456
c2 = sheet['B9']
c2.value = 456.321
workbook.save(spreadname)
Specifically, it creates a sheet called "THISONE" and the data is there.
I have a number of HTML files that I need to open up or import into a single Excel Workbook and simply save the Workbook. Each HTML file should be on its own Worksheet inside the Workbook.
My existing code does not work and it crashes on the workbook.Open(html) line and probably will on following lines. I can't find anything searching the web specific to this topic.
import win32com.client as win32
import pathlib as path
def save_html_files_to_worksheets(read_directory):
read_path = path.Path(read_directory)
save_path = read_path.joinpath('Single_Workbook_Containing_HTML_Files.xlsx')
excel_app = win32.gencache.EnsureDispatch('Excel.Application')
workbook = excel_app.Workbooks.Add() # create a new excel workbook
indx = 1 # used to add new worksheets dependent on number of html files
for html in read_path.glob('*.html'): # loop through directory getting html files
workbook.Open(html) # open the html in the newly created workbook - this doesn't work though
worksheet = workbook.Worksheets(indx) # each iteration in loop add new worksheet
worksheet.Name = 'Test' + str(indx) # name added worksheets
indx += 1
workbook.SaveAs(str(save_path), 51) # win32com requires string like path, 51 is xlsx extension
excel_app.Application.Quit()
save_html_files_to_worksheets(r'C:\Users\<UserName>\Desktop\HTML_FOLDER')
The following code does half of want I want, if this helps. It will convert each HTML file into a separate Excel file. I need each HTML file in one Excel file with multiple WorkSheets.
import win32com.client as win32
import pathlib as path
def save_as_xlsx(read_directory):
read_path = path.Path(read_directory)
excel_app = win32.gencache.EnsureDispatch('Excel.Application')
for html in read_path.glob('*.html'):
save_path = read_path.joinpath(html.stem + '.xlsx')
wb = excel_app.Workbooks.Open(html)
wb.SaveAs(str(save_path), 51)
excel_app.Application.Quit()
save_as_xlsx(r'C:\Users\<UserName>\Desktop\HTML_FOLDER')
Here is a link to a sample HTML file you can use, the data in the file is not real: HTML Download Link
One solution would be to open the HTML file into a temporary workbook, and copy the sheet from there into the workbook containing all of them:
workbook = excel_app.Application.Workbooks.Add()
sheet = workbook.Sheets(1)
for path in read_path.glob('*.html'):
workbook_tmp = excel_app.Application.Workbooks.Open(path)
workbook_tmp.Sheets(1).Copy(Before=sheet)
workbook_tmp.Close()
# Remove the redundant 'Sheet1'
excel_app.Application.ShowAlerts = False
sheet.Delete()
excel_app.Application.ShowAlerts = True
I believe pandas will make your job much easier.
pip install pandas
Here's an example on how to get multiple tables from a wikipedia html and input it into a Pandas DataFrame and save it to disk.
import pandas as pd
url = "https://en.wikipedia.org/wiki/List_of_American_films_of_2017"
wikitables = pd.read_html(url, header=0, attrs={"class":"wikitable"})
for idx,df in enumerate(wikitables):
df.to_csv('{}.csv'.format(idx),index=False)
For your use case, something like this should work:
import pathlib as path
import pandas as pd
def save_as_xlsx(read_directory):
read_path = path.Path(read_directory)
for html in read_path.glob('*.html'):
save_path = read_path.joinpath(html.stem + '.xlsx')
dfs_from_html = pd.read_html(html, header=0,)
for idx, df in enumerate(dfs_from_html):
df.to_excel('{}.xlsx'.format(idx),index=False)
** Make sure to set the correct html attribute in the pd.read_html function.
How about this?

First of all, I am new to python (practically I have learned only from Sololearn, that too only up to half course). So I request you to give me a little bit detailed answer.
My task has following broad steps:-
Delete old .xlsx file(if any)
Convert two .xls files into .xlsx file using win32, delete the first row and then delete .xls file [weird xls files already downloaded into source directory + xlrd,pyexcel show error (unsupported format or corrupt) file in opening .xls file (online analysis of file predicts it to be html/htm) ]
Get data from xlsx file
First, delete old worksheet on google spreadsheet to remove old data. Create a new worksheet with the same name. Insert data into new worksheet on the google spreadsheet.
Open second sheet(which imports data from the first sheet) and update one cell in Dummy Sheet to make sure google spreadsheet is synchronised in the background.
Now, I wrote a code by combining many codes and by using a lot of google.
The code is working fine but it takes on an avg about 65 seconds to complete the whole process.
My question has 3 parts:-
Is there any way to directly access data from .xls file?
Is there any way this code's performance can be improved.
Any other more efficient method for completing the above-said task?

I would like to read the text from a text box in an Excel File and save that value to a variable. The problem I am having is with the reading of the TextBox. I have tried several methods, this one showed the most promise, as it does not generate an error, but it does not elicit the desired result either. Any suggestions are appreciated. See code below.
import win32com.client as win32
excel = win32.gencache.EnsureDispatch('Excel.Application')
wb = excel.Workbooks.Open("C:\\users\\khillstr\\Testing\\Scripts\\Book1.xlsx")
excel.Visible = False
ws = wb.Worksheets
canvas = excel.ActiveSheet.Shapes
for shp in canvas.CanvasItems:
if shp.TextFrame.Characters:
print shp.TextFrame.Characters
else:
print "no"
Canvas has to do with graphics in excel files. I think you want access to the cells. Below is code that prints out each row as a tuple.
import win32com.client as win32
excel = win32.gencache.EnsureDispatch('Excel.Application')
wb = excel.Workbooks.Open("C:\\users\\khillstr\\Testing\\Scripts\\Book1.xlsx")
excel.Visible = False
sheet = wb.Worksheets(1)
for row in sheet.UsedRange.Value:
print row
To get the text in a textbox object on a sheet you need to use shp.TextFrame.Characters.Caption as the Characters method returns a Characters object and not a string.
import win32com.client as win32
file_name = 'path_to_excel'
excel = win32.gencache.EnsureDispatch('Excel.Application')
wb = excel.Workbooks.Open(self.file_name)
excel.Visible = False
sheet = wb.Worksheets(1)
deep = lambda r,c: sheet.Cells(r,c)
print(deep(row_num,col_num))
excel.Application.Quit()
This code will open an excel located at 'path_to_excel' and read a cell located at (Row_Number = row_num, Column_Number = col_num)
