How to Close an Excel File Opened by Another Application Using Python

Understanding the Problem

In your current automation workflow, Excel files can be opened as a result of exporting data from SAP. The challenge arises when you need to close only that particular Excel file while other Excel processes may still be running. You originally used a VBA method to close the workbook in Excel but now need to find the corresponding Python solution.

Key Requirements

You want to close only the specified Excel file.

The approach should be simple, yet effective for managing tasks in Excel.

The Solution

To address this problem, we can utilize Python’s ability to run system commands. In particular, we can use the os library to issue a command that forcibly closes Excel. Below, we detail the steps and provide you with the necessary code.

In summary, closing an Excel file opened by another application using Python is straightforward with the correct usage of the os library. By implementing the TASKKILL command in your script, you can effectively manage Excel processes as part of your automation workflow in SAP or other applications. Following these steps will streamline your process and resolve the issue of lingering Excel files that can disrupt your automation efforts.

By adopting this method, you're sure to have a cleaner, more efficient operation that ultimately saves time and effort.
