HOW IT WORKS

Built for spreadsheets that don’t already match

Most merge tools work when your spreadsheets already agree. ConsoliSheet is designed for when they don’t.

  1. GatherChoose up to 50 Excel (.xlsx) or CSV files, up to 20 MB each.
  2. CheckWe line up matching columns, even when they are in a different order or named slightly differently, and ask you to confirm any match we are not sure about.
  3. CombineDownload one Excel file with every row in the same columns, plus a Source File column showing where each row came from.

Uploaded files are temporary and are deleted within 24 hours of upload. Privacy
