#46

Problem Description

When the "data sources" tab in the provided Excel files is missing a column, such as column G in older versions of the spreadsheet, the script encounters an unhandled exception and crashes. This results in an opaque error message that does not clearly indicate the cause of the problem, leading to potential confusion and making troubleshooting difficult.

Proposed Solution

To address this issue, it is suggested to wrap the section of the code that accesses potentially missing columns in a try-except block. This block should catch IndexError exceptions and log a warning that clearly identifies the missing column and provides guidance or suggestions for resolving the issue. The script should then continue to execute, allowing for the processing of any additional data that does not depend on the missing columns.

Expected Benefits

• Improved Resilience: By catching and handling IndexError exceptions, the script will no longer crash when encountering missing columns, improving its overall resilience.
• Clearer Error Reporting: The logging of specific warnings when columns are missing will make troubleshooting more straightforward, enhancing the user experience.
• Enhanced Script Usability: Allowing the script to continue execution after encountering a missing column ensures that users can still obtain partial results from their input files, improving the script's usability in less-than-ideal scenarios.

Additional Notes

Implementing this solution does not prevent the issue of missing columns but provides a more graceful handling mechanism that benefits users by improving error transparency and script robustness.
