Apply Filter (on all the sheets) of Excel File Using the Python (Opexpyxl library)

This is a Python code snippet that uses the openpyxl library to load an Excel workbook named ‘ABC.xlsx’, apply an auto-filter to the first row of each worksheet, and save the changes back to the same file.

The code imports the openpyxl library and the get_column_letter function from the openpyxl.utils module, then iterates through all worksheets in the workbook.

For each worksheet, it selects the first row and applies an auto-filter to it. Finally, it saves the changes back to the same file.
