Excel Merger
Excel Merger is a free online tool that combines multiple .xlsx and .xls files into one workbook. It offers two merge modes: merge by sheets, which places each file's worksheets into the new workbook, and merge by rows, which appends the data from each file's first sheet into a single table. The merged file downloads automatically.
All merging happens locally in your browser, so your spreadsheets are never uploaded to a server. Free with no sign-up, it's ideal for consolidating department reports, monthly sales data, or survey results containing sensitive business data.
How to Use
- Click Select Files or drag multiple Excel files into the upload area (at least 2)
- Choose a merge mode: by sheets or by rows
- Click Start Merge
- The merged Excel file downloads automatically when done
FAQ
Is this Excel merger free?
Yes, completely free. The merged file has no watermark, there is no limit on the number of files, and no account is required.
Are my spreadsheets uploaded when merging?
No. Merging runs entirely in your browser and your files never leave your device, so financial reports and customer lists stay private.
What's the difference between the two merge modes?
Merge by sheets keeps each file's worksheets as separate sheets in the new workbook. Merge by rows appends the data from each file's first sheet into one table — the files should share the same header row for this mode.
Which formats are supported, and is there a size limit?
Both .xlsx and .xls are supported, and you need at least 2 files to merge. There is no strict size limit, but very large files may take longer to process.
