JSON Formatter

Format or minify JSON, jump to the exact syntax error, and reuse the result or create a type spec.

Input → result

Paste JSON or load a file up to 5 MiB → validate by line and column → reuse the result or create a type spec

Supported scope

Standard JSON, 2- or 4-space indentation, key sorting, files up to 5 MiB, copying, downloads, and result reuse.

Where is my input processed?

JSON source and results stay in browser memory; they are not sent to the server or Analytics, placed in the URL, or saved to browser storage.

What should I do if there is no result?

Use Go to error to select the reported line and column, then check nearby quotes, commas, and brackets before running again.
