Free online merger

Merge Excel and CSV files into one workbook.

Mirown Excel Merge creates one XLSX workbook from selected XLSX or CSV files. Each input file becomes a separate sheet, making it easier to keep source data organized after the merge.

This tool is best for clean tables, exported CSV files, simple workbook sheets, logs, lists, and lightweight spreadsheet data. Advanced formulas, macros, charts, and workbook styling may not be preserved exactly in a browser-only merge.

What this free tool includes

  • Multiple XLSX and CSV selection
  • Separate sheet for each file
  • Drag to reorder files
  • Custom workbook name
  • Free browser merge
