Paste JSON to format it with 2-space, 4-space, or tab indentation, minify it into a single line, or sort object keys alphabetically. Invalid JSON shows a parse error with line and column when available. All processing runs in your browser.
Results update as you type. Nothing is stored or sent to a server.
Use the JSON Formatter form near the top of this page. Enter the values you know, run the tool, and review the results panel. You can change inputs and run it again. Processing stays in your browser and is not uploaded to Utilnivo servers.
