Text Diff / Compare

Compare two texts line by line with color-coded differences.

How it works

1.
Paste original
Pick direction: CSV → JSON for data import (Excel export to an API) or JSON → CSV for export (API response to Google Sheets).
2.
Paste changed version
Set the delimiter: comma (standard, international), semicolon (German Excel), tab (TSV), or pipe (|, useful when text contains commas).
3.
View diff
The result appears on the right instantly. RFC 4180 compliant parsing: quoted fields, embedded newlines, and escaped quotes all handled correctly.

Which diff algorithm is used?+

Longest Common Subsequence (LCS) — the same approach as git diff.

Is there a size limit?+

Technically none, but past ~5,000 lines the computation noticeably slows.

Are my texts uploaded?+

No, everything is local.
