Sorted keys make JSON easier to read, easier to diff in version control, and easier to compare across documents. When keys are always in the same order, you can spot changes at a glance without a diff tool.

Does sorting JSON keys change the data?

No. JSON objects are unordered by specification, so a parser treats `{"b":1,"a":2}` and `{"a":2,"b":1}` as identical. Sorting only changes the display order, not the values.

Can I sort an array of objects by a field value?

Yes. Specify the key you want to sort by (e.g., "name" or "createdAt") and the tool will sort the array elements by that field's value, handling strings, numbers, and ISO date strings.

What happens to nested objects when I sort?

Sorting is applied recursively. Every nested object in the document has its keys sorted, and every nested array of primitives is also sorted. This ensures the entire document is consistently ordered.

About JSON Sorter

JSON Sorter organizes your JSON data in a predictable order. You can sort all keys alphabetically throughout a document, sort arrays of primitives by value, or sort arrays of objects by a specific key. Sorted JSON is easier to diff, review, and maintain — especially useful for configuration files and data that is compared over time.

✓Sort all object keys alphabetically throughout the entire document
✓Sort arrays of strings or numbers by value (ascending or descending)
✓Sort arrays of objects by a specified key
✓Recursive — sorts nested objects and arrays at every level
