About Sort JSON Keys

Sorting JSON keys alphabetically makes JSON objects deterministic and easier to diff. When two JSON objects have the same data but different key order, a plain text diff shows every line as changed. With sorted keys, only genuinely changed values appear in diffs. This tool performs a deep sort — nested objects at any depth are also sorted. Arrays are left in their original order since array position is semantically significant.

Private & free — this tool runs entirely in your browser.
