Combine multiple Excel files into one workbook, instantly. 100% free, no sign-up — nothing ever leaves this browser tab.
Merge Excel Files takes two or more workbooks and combines their first sheets into a single workbook, one sheet per source file. It's the spreadsheet equivalent of merging PDFs — useful whenever data is scattered across separate files that belong together.
Teams often end up with the same type of report split across several files — one per month, region, or team member. This tool brings them back into a single workbook so you can review, sort, or analyze everything together, without manual copy-pasting.
No installs, no accounts — just your browser doing the work.
Scroll up (or tap the button above) to load the tool instantly — no account or install needed.
Add your file, text, or numbers into the tool above.
Sensible defaults are already selected — tweak anything you need.
Your result is generated locally and ready in seconds — no waiting room.
Each source file becomes its own labeled sheet in the merged workbook.
Your files are read directly in this browser tab and never uploaded.
No server queue — the merge happens the moment you add your files.
Because Merge Excel Files runs locally, teams handling sensitive data — finance, HR, legal, operations — can use it without the compliance questions that come with uploading documents to a third-party server.
Only the first sheet from each workbook is included, keeping the merged file simple and predictable.
No artificial limit — you can add as many files as your browser can comfortably handle.
No. Merge Excel Files runs entirely in your browser using the SheetJS library.
