I use Openpyxl in Python to write some data in an Excel file using Workbook.
When I want to save the workbook to a file, I can only provide a filename argument, so I can not write files in other directories.
here is my sample code:
import openpyxl
file_name = "sample.xlsx"
wb = openpyxl.Workbook()
# writing some data to workbook
wb.save(filename=file_name)
I have checked the documentation via this link and found nothing more.
Python: 3.10.7
Openpyxl: 3.0.10
Can you help me provide workarounds to solve this problem?
You can indicate a full path + filename, and it will create a file where you need it:
wb = Workbook()
wb.save(r'D:\folder\folder\folder\Filename.xlsx')

I am using Python 3.7 and using OpenPyxl to read the sheet names from a large excel workbook (29MB) with 10 tabs.
import openpyxl
from openpyxl import load_workbook
wb = load_workbook(filename='h:\\Master_Portfoliio.xlsx')
print(wb.sheetnames)
The code above works for smaller files but when I use the same code for this file, the code just hangs. I would like to read the sheet names and then remove a tab and then copy a tab from another excel workbook into this workbook.
Have you tried the read_only = True flag?
wb = load_workbook(filename='h:\\Master_Portfoliio.xlsx', read_only = True)
I have file path problem when loading an Excel file using openpyxl.
>>>openpyxl.__version__
'2.5.12'
>>>jupyter.__version__
'5.7.4'
import os
import openpyxl
from openpyxl import Workbook
from openpyxl import load_workbook
from openpyxl.reader.excel import load_workbook
>>>os.getcwd()
'/Users/barbara/Documents/17_BMO'
path = "Users/barbara/Documents/17_BMO/Region.xlsx"
wb1 = openpyxl.load_workbook(path)
Instead of loading the workbook, I instead receive the error message:
FileNotFoundError: [Errno 2] No such file or directory: 'Users/barbara/Documents/17_BMO/Region.xlsx'
I fixed it.
I have two same excel files saved in Desktop and Documents. I firstly pointed workbook's path to Desktop, somehow, I can't load excel in Python, then I changed the path to Documents, it didn't work neither. Later on, I changed back to Desktop as my path, it worked. Don't why.
I am trying to load an existing Excel file and create a new sheet inside that workbook, but my code is not working using openpyxl.
rb = load_workbook("C:\Raw_Dump.xlsx")
rb.create_sheet("Sheet2")
sheet1 = rb.worksheets[0]
Any help would be appreciated.
You have to save the workbook to the same filename:
rb.save(r"C:\Raw_Dump.xlsx")
full working example:
import openpyxl
ws_name = r"Raw_Dump.xlsx"
rb = openpyxl.load_workbook(ws_name)
rb.create_sheet("Sheet2")
rb.save(ws_name)
I spent a long time searching this and found the best way is to do sheet removal. The code below worked for me:
for sheet in wb.sheetnames:
if sheet not in "MY_SHEET_I_WANNA_KEEP":
rm_sheet = wb[sheet];
wb.remove_sheet(rm_sheet)
wb.save("JustOneSheet.xlsx")
I want to insert a Image(object) in MS-Excel Report which i am generating using openpyxl utility. Is there a way to do it using some python utility?
Openpyxl allows you to write images into your Excel files! Here it is in the official documentation.
import openpyxl
wb = openpyxl.Workbook()
ws = wb.worksheets[0]
picture = openpyxl.drawing.Image('/path/to/picture')
picture.anchor(ws.cell('cell to put the image'))
ws.add_image(picture)
wb.save('whatever you want to save the workbook as')
This code of course refers to creating a new workbook and adding the image into it. To add the image to your preexisting workbook you would obviously just load that workbook using load_workbook.
I am having problems appending issues appending data to an xls file.
Long story short, I am using a program to get some data from something and writing it in an xls file.
If I run the script 10 times, I would like the results to be appended to the same xls file.
My problem is that I am forced to use Python 3.4 and xlutils is not supported, so I cannot use the copy function.
I just have to use xlwt / xlrd. Note, the file cannot be a xlsx.
Is there any way i can do this?
I would look into using openpyxl, which is supported by Python 3.4. An example of appending to a file can be found https://openpyxl.readthedocs.org/en/default/. Please also see: How to append to an existing excel sheet with XLWT in Python. Here is an example that will do it. Assuming you have an Excel sheet called sample.xlsx:
from openpyxl import Workbook, load_workbook
# grab the active worksheet
wb = load_workbook("sample.xlsx")
ws = wb.active
ws.append([3])
# Save the file
wb.save("sample.xlsx")
