Studied and referred to implementation methods for importing Excel data into the grid.

Analyzed how the import query works — how it reads data from the Excel file and inserts or updates it in the database.

While testing, you found an error in the import query, which was preventing data from being imported correctly.

Investigated the issue by checking the query structure, parameters, and data mapping.

Started working on a fix to correct the import query so that the Excel data could be successfully loaded into the grid.
