Merge Mode

📚 Stack into One Sheet

Combines all rows from all files into a single sheet, matching columns by header name. Best for merging the same report from multiple months.

📑 Keep as Separate Tabs

Each uploaded file becomes its own sheet/tab in one workbook. Best for combining different report types.

Files are processed entirely in your browser — nothing is uploaded to any server.
