I am starting on a code that loads and edits excel (the version I am using is office 2017) sheet using openpyxl. Right now I am still trying to wrap my head around how this module works, here's the code
import openpyxl
from openpyxl import load_workbook
from openpyxl import workbook
from openpyxl.compat import range
from openpyxl.utils import get_column_letter
import os
os.chdir("D:\Scripts\Python\Testing Scripts\My Excel Folder")
wb = load_workbook("MyExcel.xlsx")
names = wb.sheetnames()
print(names)
print(type(wb))
and the error I receive is,
TypeError: 'list' object is not callable
For the string of code
names = wb.sheetnames()
wb.get_sheet_names() returns the list of all the sheets in that excel workbook.
print (wb.get_sheet_names())
for the latest openpyxl to avoid warning:
print (wb.sheetnames)
if you want to access a particular sheet
ws = wb.get_sheet_by_name(name = 'Sheet 1')
Use: wb.sheetnames
Example -
names = wb.sheetnames
print(names)
Do not use: get_sheet_names()
If you will use this, you will get this Warning.
DeprecationWarning: Call to deprecated function get_sheet_names (Use wb.sheetnames).

I am trying to use a simple delete_rows line to clear some data our of a sheet after importing via openpyxl, but the function is unrecognized by my Visual Studio Code.
When I use from openpyxl import load_workbook, the load_workbook text is grayed out like it's not recognized, but my openpyxl.load_workbook line is working. For some reason when I type out delete_rows the function is not autofilled like it's not being recognized.
Tried pip install openpyxl, but I already have the latest.
delete_rows is a method of the Worksheet object (docs), not a function like load_workbook, so you do not need to import it, just call it on a Worksheet (see also this demo page).
from openpyxl import load_workbook
wb = load_workbook("<xlsx_file_name>")
ws = wb.active
ws.delete_rows(2, 1)
I've import a xlsx sheet into Python 3.6 by using import openpyxl and now am trying to access the Cell Object by doing the following (see below), but I immediately get an error message which I don't know what it means?:
Warning (from warnings module):
File "__main__", line 1
DeprecationWarning: Call to deprecated function get_sheet_by_name (Use wb[sheetname]).
Here is my code:
import openpyxl
wb = openpyxl.load_workbook('c:\\users\\user1\\AppData\\Local\\Programs\\Python\\Python36-32\\example.xlsx')
sheet = wb.get_sheet_by_name('Sheet1')
Rather than what you're doing, it's telling you to use a different format
wb['Sheet1']
If you plan on using your script in the future, when that library is upgraded, it may break because you're using deprecated functions
the right code :
import openpyxl
wb = openpyxl.load_workbook('c:\users\user1\AppData\Local\Programs\Python\Python36-32\example.xlsx')
sheet = wb['Sheet1']
If you don't anticipate to know beforehand what the sheetname is, then your code should be:
sheet = wb[wb.sheetnames[0]]
...which will automatically choose the left most sheet in the workbook
Furthermore, it is important to note that wb[0] produces a string object...
>>> wb.sheetnames[0]
'Sheet1'
and wb[wb.sheetnames[0]] produces a 'openpyxl.worksheet.worksheet.Worksheet' object...
>>> wb[wb.sheetnames[0]]
<Worksheet "Sheet1">
>>> type(wb[wb.sheetnames[0]])
<class 'openpyxl.worksheet.worksheet.Worksheet'>
This is important on how you plan to work with this object (e.g. iterating over your worksheet).
Please try below code, hope it will help:
import openpyxl
wb = openpyxl.load_workbook('c:\\users\\user1\\AppData\\Local\\Programs\\Python\\Python36-32\\example.xlsx')
sheet = wb['Sheet1']
I am getting the above error when trying to create a new workbook with the following commands:
import xlwt
workbook = xlwt.Workbook()
workbook.save(‘my_file.xls’)
I am new to Python and following a guide but I can’t find what this error means
This works for me. I think your workbook needs to be setup with a sheet to be valid.
import xlwt
workbook = xlwt.Workbook()
workbook.add_sheet("Sheet")
workbook.save("myfile.xlsm")
This is my code so far:
import os
import openpyxl
os.chdir('C:\\Python34\\MyPy')
wb=openpyxl.load_workbook('example.xlsx')
wb.get_sheet_names()
But I get these errors:
Warning (from warnings module):
/File "main", line 1
DeprecationWarning: Call to deprecated function get_sheet_names (Use wb.sheetnames).
['Sheet1', 'Sheet2', 'Sheet3']
Warnings aren't errors - they won't hinder your program from running. In case of deprecated warnings: you use a feature that will be removed in future versions so the devs lable it deprecated.
It may work now, but next version it may no longer as this feature was removed - then you will get an error.
You can fix it like this:
wb.sheetnames # all names
sheet = wb["UseThisSheet"] # select a certain sheet by name
for sheet2 in wb: # or go over all sheets
print(sheet2.title)
sh = wb.active # normally sheet at index 0 if you create an empy one

Here is a short example on how to create a workbook (my answer to some other xlsx question): https://stackoverflow.com/a/48782382/7505395
Since I bounce around in a few different worksheets in my python, I needed the whole list to work from. I added the following
wbInputFile = load_workbook(inFile)
sheetList = wbInputFile.sheetnames
worksheet = wbInputFile[ sheetList[0] ]
# now I am able to run through the rows and get the info
for row in range(2,worksheet.max_row ):
# get the values for each cell needed
It gives a warning , but the below code works fine (using Python3 ).I tried with wb.sheetnames instead of wb.get_sheet_names()
import openpyxl
path="C:\\Users\user1\PycharmProjects\Projectstatus\My Python.xlsx"
wb=openpyxl.load_workbook(path)
print(wb.sheetnames)
from openpyxl import load_workbook
#Load in the workbook
wb = load_workbook('YourFileName.xlsx')
wb.sheetnames # all names
My goal is to read in an excel file and view the codes in a pandas dataframe (i.e. '= A3') rather than the resulting values from excel executing the codes, which is the pandas default if read in using pandas.
My goal was described here: How can I see the formulas of an excel spreadsheet in pandas / python?
Openpyxl is supposed to support this, but I can't get the import to function correctly. Anyone spot the error?
import pandas as pd
from openpyxl import load_workbook
from openpyxl.utils.dataframe import dataframe_to_rows
df = pd.DataFrame()
wb = load_workbook(filename = 'name.xlsx')
sheet_names = wb.get_sheet_names()
name = sheet_names[0]
sheet_ranges = wb[name]
df = pd.DataFrame(sheet_ranges.values)
> AttributeError: 'Worksheet' object has no attribute 'values'
(Note: the exact implementation of the answer at the linked question yields KeyError: 'Worksheet range names does not exist.' My code above resolved this, but then gets stuck as described.)
Check your version of openpyxl, It seems you have an older version.
openpyxl 2.4.2
import openpyxl
print(openpyxl.__version__)
Values property for worksheets were added only from 2.4.0-a1 (2016-04-11)
