JSON formatter and minifier
Make JSON readable, or make it small. If it is not valid JSON, you see where the mistake is.
Accepts
JSON (.json). Other file types are not converted on this page; the File Converter hub takes every kind it knows.
How to convert
- The JSON is parsed and written back with the indent you choose. None (minified) writes one line with no spaces.
- A mistake, such as a missing comma or quote, is reported with its line and column.
Your files stay on this device. Nothing is uploaded: the conversion runs in your browser, and the file is never sent to ITpris Verktyg or to any other server.
Questions
Does it change my data?
No. Only the spacing changes; keys keep their order.
Can I type or paste instead of a file?
Yes. Type or paste in the box under the converter, and the preview updates as you type.
Are my files uploaded?
No. The conversion runs in your browser, on this device. Your files are not sent to ITpris Verktyg or to any other server.
