Merge Excel Files — Free, No Signup

Combine several Excel workbooks into one — as a single combined sheet with columns matched by header, or keep every sheet separate in one merged workbook. Runs entirely in your browser. No signup required.

How it works

1. Upload multiple Excel workbooks: Nothing is uploaded to a server.
2. Choose combined or separate sheets: Merge into a single sheet with columns matched by header, or keep every sheet separate inside one merged workbook.
3. Download the merged workbook: Processed entirely in your browser.

Frequently asked questions

What’s the difference between the two merge modes?
Combined mode matches columns by header name into one unified sheet; "keep sheets separate" instead bundles every original sheet, unchanged, into one workbook file.

Is my spreadsheet data uploaded anywhere?
No — merging happens entirely on-device.

What if workbooks have columns in different orders?
In combined mode, columns are matched by header name rather than position, so a different column order still merges correctly.
