Why should I sort JSON keys alphabetically?

Sorting JSON keys alphabetically makes large JSON files easier to read, compare, and maintain. It produces consistent output that reduces merge conflicts in version control, makes code reviews simpler, and helps you quickly find specific keys in deeply nested objects.

Does sorting JSON keys change the data or break anything?

No. The JSON specification states that objects are unordered collections of key-value pairs, so reordering keys does not change the semantic meaning of the data. All values, arrays, and nested structures are preserved exactly as they are — only the key order changes.

Can this tool handle JSON with comments or trailing commas?

Yes. This tool supports JSON5-like input by automatically stripping single-line comments (//), multi-line comments (/* */), and trailing commas before processing. This makes it easy to sort configuration files like tsconfig.json or .eslintrc that often contain these non-standard features.

About JSON Key Sorting

JSON objects are technically unordered, but in practice, consistently ordered keys make a huge difference for readability, debugging, and version control. This tool sorts all object keys alphabetically while preserving array order and all data values.

When teams commit JSON configuration files to Git, unsorted keys cause unnecessary merge conflicts and noisy diffs. Sorting keys before committing ensures that changes are meaningful and easy to review.
