JSON Sort Keys

• JSON Formatter
• JSON Merge
• JSON Minifier
• JSON Tools

Sort every object’s keys in your JSON alphabetically. Nested objects are processed recursively; array element order is left unchanged. Choose 2 or 4 space indent for the output. Paste, upload, or drag-and-drop; invalid JSON shows an error and snippet with links to the Formatter and Validator. Clear resets input, output, and file. Download or copy the result. All processing is client-side.

• Recursive sort: Every object in the tree has its keys sorted alphabetically. Only object keys are reordered; arrays keep their element order.
• Indent option: Output is pretty-printed with 2 spaces or 4 spaces so the result is readable and diff-friendly.
• Error handling: Invalid JSON shows the parser message and, when available, a snippet around the error. Links to Formatter and Validator help you fix the input.
• Clear: One click clears the input, output, and file input so you can load different JSON.

Powered by browser APIs and client-side processing.

Object key order in JSON is not guaranteed across systems, so diffs between two versions often show meaningless reordering. Sorting keys alphabetically gives a stable, deterministic order so version control and comparisons highlight real changes. Running the sort in the browser keeps your data private and works offline after the page loads.

• Indent: 2 spaces or 4 spaces for the output. Applied to the sorted JSON only.
• Sort Keys: Parses the input and sorts all object keys recursively. Arrays are unchanged.
• Download / Copy: Export the result as a .json file or copy to clipboard.
• Clear: Clears input, output, any error, and file input.
