JSON Formatter & Validator

Check JSON syntax or format with two-space indentation.

Ready. Paste your input or load an example.

Uses JavaScript JSON.parse / JSON.stringify. Duplicate keys keep the last value; large numbers may lose precision. Validation checks syntax only.

A QUIETER KIND OF TOOLBOX

Your browser does the work.

Transformations run locally in JavaScript. Input is not uploaded, stored in cookies or saved in browser storage. This page has no analytics or third-party scripts.
