Excel Sheet Merger

Upload multiple .xlsx or .xls files — matching sheets are merged in order, unique sheets carry over.

Merge Excel files online — free, instant, no login

Upload two or more Excel workbooks (.xlsx or .xls) and this tool will combine them into a single file. Worksheets with matching names are merged row by row, with rows from each file appended in upload order. Worksheets that only exist in one file are carried over as-is. Your data never leaves your browser — everything runs locally.

✓ Supports .xlsx & .xls ✓ Multiple files at once ✓ Matching sheets merged ✓ Unique sheets preserved ✓ Duplicate row handling ✓ Runs in browser — no upload

Drop multiple files at once, or click to browse. Files merge top-to-bottom in upload order.

How It Works
📂 Upload your files
Drop multiple .xlsx or .xls files. The first file is the base — others are merged into it in order.
🔀 Sheets are matched by name
Worksheets with the same name are merged row by row. Sheets unique to one file are carried over as-is.
⬇ Download the result
Your merged file is generated in the browser and downloaded directly — nothing is sent to a server.
