JSON Formatter & Validator
Format, minify, and validate your JSON data instantly.
What Is a JSON Formatter
JSON (JavaScript Object Notation) is a lightweight data format used to store and exchange data. When JSON is minified or poorly formatted it becomes very hard to read. Our JSON Formatter and Validator instantly beautifies your JSON with proper indentation, validates whether it is correct, and can also minify it back to a compact form for production use.
How to Use
Step 1 – Paste Your JSON
Copy and paste your raw or minified JSON data into the input box on the left.
Step 2 – Choose an Action
Click Format to beautify it, Minify to compress it, or Validate to check if it is valid JSON.
Step 3 – Copy the Output
The result appears in the dark output box on the right. Click Copy Output to use it.
