How to use CSV Compare

Find additions, removals, and changed values in comma-separated data while handling quoted commas, escaped quotes, and line breaks correctly.

Three simple steps

  1. Upload one UTF-8 CSV file on each side or paste both datasets.
  2. Choose format-aware comparison to normalize valid CSV or exact source comparison to include quoting and line-ending changes.
  3. Review the summary in side-by-side or unified view and copy the result you need.

CSV comparison modes

  • Format-aware comparison parses comma-separated rows and fields, then normalizes valid quoting and line endings.
  • Row and column order remain meaningful; the tool does not match records by a chosen key.
  • Exact source comparison shows presentation changes as well as data changes.

Frequently asked questions

Can CSV fields contain commas or line breaks?

Yes. Properly quoted commas, escaped quotes, and line breaks are parsed in format-aware mode.

Does the tool match rows by an ID column?

No. It compares rows in their current order. Sort both files consistently first when records should align by an identifier.

Can I upload CSV files?

Yes. Load one UTF-8 .csv file on each side, up to the limits shown in the workspace.
