Excel Sheet Merger

Combine sheets from several workbooks into one file.

Local processing · No file upload · No API key required

Combine XLSX sheets as separate tabs or append their rows. This is a values-only data merge: cached formula results are used; styles, charts, images and macros are not copied.

How to use Excel Sheet Merger

  1. Choose your input, then load and inspect the preview.
  2. Configure the fields and options for your output.
  3. Create the result, review it and download a new file. Your original is unchanged.

Privacy and limits

Files and passwords stay on this device. File contents are not sent to AllNewTools. Account and credit requests do not contain your dataset. XLSX files are supported; save legacy XLS workbooks as XLSX first. Workbook formulas are never executed or recalculated, and data exports do not preserve workbook styling, macros, charts or images. Large inputs are bounded to protect browser memory.

CSV contains values only and has no cell types or formatting. Protect formula-like text before opening untrusted CSV in spreadsheet software. Use XLSX when identifiers must remain text.
