How to use JSON Key Sorter

Paste your JSON and the tool returns the same data with every object's keys sorted alphabetically at all nesting levels.

Frequently asked questions

Why sort JSON keys?

Consistent key order makes JSON easier to read and produces clean, minimal diffs in version control.

Does it sort nested objects too?

Yes — the sort is recursive, so keys inside nested objects and array elements are ordered as well.

Are array orders changed?

No — only object keys are reordered. Array element order is preserved because it is meaningful.
