JSON Sort Keys Deeply
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.
How to use JSON Sort Keys
- Paste your JSON.
- Click sort to alphabetize the keys.
- Copy the sorted JSON.
Frequently asked questions
How deep does the key sorting go?
It sorts object keys alphabetically at every nesting level, so nested objects are ordered too, not just the top level.
Why sort JSON keys?
Sorting produces deterministic output, which makes diffs stable and configs reproducible regardless of the original key order.
Does sorting reorder array elements?
No. Array element order is meaningful and is preserved; only object keys are alphabetized.
