How to use this office tool

  1. Upload a workbook containing the sheets to combine.
  2. Review the detected sheet names and choose the header row.
  3. Merge the sheets, inspect the combined preview, and download XLSX.

What this tool does

Reads all worksheets, aligns them by position, keeps one header row, and appends each sheet's data into a new worksheet.

Combined table = first header + data rows from each selected workbook sheet.

Sheets should use compatible column order. The source-sheet column helps identify where each row came from.

Supported formats

Accepts XLSX and XLS workbooks plus single-table CSV or TSV. Output is one XLSX worksheet.

Tips for better results

  • Standardize headings and column order before merging.
  • Keep the source-sheet label for auditability.
  • Review sheets with extra title rows before processing.

FAQ

How are Excel sheet headers handled when sheets are merged?

The first sheet supplies the header, and the corresponding header row is skipped in later sheets.

Can I tell which worksheet each merged row came from?

Yes. The output includes a Source Sheet column.

Do worksheet columns need to be in the same order?

Yes. This browser tool stacks by column position rather than performing a semantic column match.

Will formulas recalculate after sheets are merged?

Formula text can be preserved, but this tool does not reproduce the full Excel calculation engine.

Can I merge sheets from several separate files?

This page combines sheets within one workbook. Use Merge Excel Files for multiple workbooks.
