Text & JSON Diff Checker
Compare two texts or JSON documents line by line. Side-by-side or inline, ignore whitespace and case, sort JSON keys before comparing, and copy a unified-diff patch — all in your browser.
Differences
Enter text on both sides to see the differences.
Tip: use the JSON / YAML Toolkit to format or validate before diffing, and the Encoder / Decoder for Base64/URL data. Everything here runs locally — nothing is uploaded.
