JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate.
Paste your JSON into the input area. The tool will automatically validate it and pinpoint the exact error position and cause if any issues are found.
The tool processes JSON in the browser. We recommend files under 5MB. Larger files may cause slow browser response.
