FAQ
How do I sort JSON keys alphabetically?
Paste your JSON into the tool; it automatically reorders every object's keys from A to Z. The sorted result appears immediately, ready to copy.
Does the sorting apply to nested objects?
Yes, the sorting is recursive: keys of nested objects at every level are sorted too. The order of elements inside arrays, however, is preserved.
Does sorting keys change the JSON values?
No, only the key order changes; the values, types, and array contents stay identical. The JSON remains semantically equivalent to the original.
