What is JSON Sorter?
A JSON key sorter rearranges the keys in JSON objects into alphabetical order, recursively at every nesting level. This produces consistent, predictable JSON output that is easier to diff, version control, and compare. Sorted keys also make JSON more scannable for humans since related keys appear together.
How to Use
- Paste your JSON data into the input area
- The sorted JSON appears instantly in the output panel
- Keys are sorted alphabetically (case-insensitive) at every nesting level
- Array element order is preserved — only object keys are sorted
Examples
Sort flat object
Sort nested object

Frequently Asked Questions
Is the sorting case-sensitive?
No. The sorting is case-insensitive, so "Address" and "address" are treated as equivalent for ordering purposes. If two keys differ only in case, their relative order follows their original position.
Does it sort arrays too?
No. Only object keys are sorted. Array elements maintain their original order because array position is meaningful (the first element is different from the second). Nested objects within arrays will have their keys sorted.
Why sort JSON keys?
Sorted keys produce deterministic output — the same data always produces the same JSON string. This is essential for version control diffs, caching (consistent hash keys), API response comparison, and reducing merge conflicts in JSON config files.
