JSON
Sort every object key alphabetically — produce stable, canonical JSON for diffs and reviews.
Sorting happens locally in your browser. Nothing is uploaded, logged, or stored.
JSON objects are unordered by specification, but in practice key order changes between tools, languages, and versions. That makes text diffs noisy: two semantically identical documents look different just because keys moved. Sorting keys recursively produces a canonical form — feed both versions through this tool and your diff shows only real data changes.
The sorter walks the whole tree: nested objects are sorted too, and arrays of strings/numbers can be sorted on demand. Pair it with the JSON Diff tool for noise-free comparisons, or the JSON Formatter if your input fails to parse.
Sort two API snapshots before diffing them so key reordering stops drowning out the real changes.
Canonical JSON gives you a repeatable string to hash when you need a content fingerprint of a payload.
Format, minify, and validate JSON with precise error location. Runs entirely in your browser.
Check JSON syntax with precise line and column error location, plus a structural summary of the document.
Compare two JSON documents and see every added, removed, and changed value by path.
Explore JSON as a collapsible tree with syntax highlighting — great for large API responses.
