JSON Formatter
Format and validate JSON without uploading it.
Ready when you are. Your input stays in this page.
How it works
Paste JSON and select Format JSON. Valid JSON is displayed with two-space indentation. Invalid input produces an error, leaving no misleading formatted output.
Limits
This formats JSON using the browser’s native parser. It does not preserve duplicate keys, number precision beyond JavaScript’s safe range, or original whitespace. Avoid using it for transformations where those details must survive.
No inputs are uploaded or stored. This file has no external dependencies.
