About JSON Key Sorter
JSON Key Sorter is an online tool that sorts JSON object keys in alphabetical order (ascending or descending). Organize messy JSON data from REST API responses, package.json, tsconfig.json, and various configuration files to maintain consistency across your team.
Recursively sort nested objects and customize indentation width (2 spaces, 4 spaces, or tabs). Advanced options include case-insensitive sorting and numeric-aware key ordering, perfect for APIs that mix text and numeric keys.
All processing runs entirely in your browser with no data sent to any server. Keep your internal API specifications and sensitive configuration files private while improving code consistency.
How to use JSON Key Sorter
- Paste or type your JSON string into the input textarea.
- Choose the sort order (A→Z ascending / Z→A descending). Enable case-insensitive or numeric sort options if needed.
- Select whether to sort recursively and choose your indentation style (2 spaces, 4 spaces, or tabs).
- Click the Sort button to display the sorted JSON in the output area.
- Use the Copy button to copy the result to your clipboard.
Benefits of JSON Key Sorter
- Unifying key order makes Git diffs cleaner and reduces unnecessary noise.
- Focus on meaningful changes during code reviews without being distracted by key ordering differences.
- Case-insensitive and numeric sorting options handle complex JSON structures with mixed key types.
- Browser-only processing keeps internal API responses and sensitive config files safe.
- Recursive sorting organizes even deeply nested JSON structures in one click, improving maintainability.
