About Semantic JSON Compare / Diff
Free semantic JSON compare and JSON diff tool. Paste two documents to see added, removed, and changed paths — ignores key order and formatting so you compare objects, not text lines. Runs 100% in your browser.
Semantic JSON compare walks both documents as data trees and reports path-level differences: keys only on the left (removed), only on the right (added), or values that changed — unlike a plain text diff that flags reordered keys and pretty-print newlines as noise.
Both sides must be valid JSON first. If either side fails to parse, SparkJSON shows that syntax error instead of a misleading partial diff. Comparison never leaves your browser.
Frequently asked questions
- Does order of object keys matter?
- No. Object keys are compared as a set. Array order does matter — index 0 is compared to index 0.
- Can I compare minified and beautified JSON?
- Yes. Whitespace is irrelevant after parse. Only structural and value differences are reported.
- Is my data uploaded?
- No. Diffing runs entirely in your browser.
