Compare Two JSON Files
Compare two JSON documents structurally so key order and formatting do not drown out the real changes. Runs entirely in your browser.
Runs entirely in your browser — your file is never uploaded.
Questions
- Does reformatting show up as a change?
- No. The comparison is structural, so whitespace and key order are ignored and only genuine differences in values appear.
- Can I compare API responses safely?
- Yes — and it is worth caring, because API payloads routinely contain tokens and personal data. Nothing you paste here leaves your browser.
