JSON Helper. View, format, and validate JSON data.

Pretty print or minify JSON with a single button click.

JSON file size

0 Bytes | Gzipped: 8 Bytes | String length: 0

How to use JSON helper tool?

Paste your JSON data to the main editor input. Use "Format" button to pretty print and "Minify" button to compress JSON. You can insert a JSON example by using the corresponding button.

JSON is validated every time you change a text in the text area. You will see JSON parse error under the editor if JSON data is not valid.

It's quite interesting to see the benefits of compression/minimization. The size of JSON text is displayed at the bottom of the editor. There are two values: size in bytes, size with GZIP compression, and the count of characters (string length).
