Python - using win32com to access Excel file

To use win32com to access an Excel file in Python, you can leverage the win32com.client module. Here's a basic example:

import win32com.client # Create a new Excel application excel_app = win32com.client.Dispatch("Excel.Application") # Open an existing workbook workbook = excel_app.Workbooks.Open(r'C:\path\to\your\excel\file.xlsx') # Access a specific worksheet worksheet = workbook.Worksheets('Sheet1') # Read data from a cell cell_value = worksheet.Range('A1').Value print(f'Value in cell A1: {cell_value}') # Modify data in a cell worksheet.Range('B2').Value = 'New Value' # Save the changes workbook.Save() # Close the workbook and Excel application workbook.Close() excel_app.Quit()

Make sure to replace the file path in Open method with the actual path to your Excel file. The r before the string denotes a raw string, which is useful for file paths to handle backslashes.

You'll need to have the pywin32 module installed. You can install it using:

pip install pywin32

This example covers basic operations like opening a workbook, accessing a worksheet, reading and modifying cell values, saving changes, and closing the workbook and Excel application. Adjust it according to your specific requirements.
