About the JSON Sort Keys Formatter
JSON Sort Keys sorts all JSON object keys alphabetically, including nested objects, then displays it prettified (Format) or compacted (Minify).
How it works: the tool parses the JSON, recursively sorts each object's keys, then rewrites it. Array element order is preserved (only object keys are sorted).
Sorting keys is useful for stable diffs across versions, config normalization, and making it easier to compare two JSON documents that should be equivalent.
FAQ
Can this JSON Sort Keys tool both format and minify?
Yes. One page with a toggle — Format mode prettifies (beautifies) with indentation, and Minify mode compacts it. No need for two separate pages.
Is my code sent to a server?
No. JSON Sort Keys is processed entirely in your browser using JavaScript/WebAssembly. Your code never leaves your device.
