FAQ

How do I merge Excel files for free?

Add the workbooks and this page copies every sheet from every file into one .xlsx, renaming any clashing sheet names — on your device with no upload.

Are my spreadsheets uploaded anywhere?

No. Merging runs entirely in your browser and nothing is transmitted or stored, which you can verify by turning off your Wi-Fi.

Does it merge the data or keep sheets separate?

It keeps each source sheet as its own sheet in the combined workbook, so nothing is overwritten.

What if two sheets have the same name?

Duplicate names are automatically suffixed so both survive.

Limits

Combines whole sheets; it does not join or dedupe rows across sheets.
