I'm working on a data project integrating python in Google Colab and Excel 365 on Win 8.1. My python code collects new data updates on a regimented schedule and then exports/writes (e.g. overwrites, not appends the data) like to a report on an Excel spreadsheet.
I have no issue getting this to work going to a standalone spreadsheet.
I know I could potentially do all this in Python and not use Excel at all, but I prefer not to reinvent the wheel and not spend hours hardcoding all the formulas and links already existing in Excel.
My goal is to:
Use new data from my Colab export to populate/overwrite a data table on Sheet A in an existing Excel workbook.
Then I have a separate Sheet B in the same Excel workbook performing calculations via pre-existing links connecting to the original data table on Sheet A. I then want the links to auto update each time my python export updates the data table on the first sheet.
The issues I am running into are that if I use the df.to_excel function to export the data and even if I use the spreadsheet name parameter, the export overrides the data table and names the tab okay, but wipes out any other pre-existing sheets within the same workbook.
So I attempted a work around by exporting to an external workbook and then trying to update the links in the second workbook automatically. Problem is the links don't appear to update without the source data file and the second workbook with the links both being manually opened and then the updated file manually saved.
Does anybody know a way to use python in Google Colab to:
Overwrite a specific sheet within an Excel workbook without wiping out the other existing sheets? And then have the links on another sheet automatically update which are connected to the new data?
Auto update external links between separate Excel workbooks while the files are unopened?
Control an instance of excel that can open both files to allow the links to auto update and then save and close the files automatically?
I found a post from some years ago that identified a win32 package hat appeared to be able to control instances of excel. When I try doing a pip install in Colab I got an error that the package was unrecognized or doesn't exist.
Ideally, I would prefer not to use VB if at all possible to solve this.
Any solutions are much appreciated.
Thanks in advance.
