Merge Workbooks
Merge multiple Excel workbooks into one. Each source sheet appears as a sheet in the output. Cell values are preserved; complex cell formatting (styles, conditional formatting, charts) is not.
About Merge Workbooks
Merge Workbooks combines several Excel files into a single workbook, where each source sheet shows up as its own tab in the result. It's the tool for pulling monthly exports, per-region reports, or scattered .xlsx files into one place. Everything runs locally in your browser — no upload — and cell values are preserved, though rich formatting is not.

Frequently asked questions
How are the sheets arranged in the output?
Each sheet from each input workbook becomes its own sheet in the merged file, preserving the source data layout.
Is formatting kept?
Cell values are preserved, but complex formatting — styles, conditional formatting, and charts — is not carried over.
What input format is required?
Modern .xlsx workbooks (the OpenXML spreadsheet format).
Does it merge data within a sheet, or just collect sheets?
It collects sheets side by side; it does not concatenate rows across sheets. For combining rows of like-shaped data, convert to CSV and use CSV Merge.
Are my files uploaded?
No. The merge happens entirely in your browser; the workbooks stay on your device.
