Sort the keys of a JSON object alphabetically at every nesting level, which is the trick for producing deterministic, diff friendly JSON. When two config files or API snapshots have the same data but their keys are in a different order, a plain text diff lights up with noise. Sorting keys deeply makes the output stable so real changes stand out. This tool parses your JSON, walks every nested object, and rebuilds it with keys in ascending order while leaving array element order untouched, since arrays are ordered by meaning. You can choose ascending or descending order and pretty or compact output. Paste your JSON, pick your options, click sort, and copy the result. Everything runs locally in your browser, so your data never leaves your machine.
