Text Diff Checker

Compare two text blocks with side-by-side line changes and word-level highlights.

Paste two text blocks to inspect line-level changes side by side.

Common edge cases

Whitespace-only changes are still changes. Review formatted JSON or source text carefully before copying results.

Language snippets

git diff --no-index old.txt new.txt

FAQ

Can I compare formatted JSON?

Yes. Formatting JSON first can make structural changes easier to inspect.
