## How it works

The JSON tool helps you organize unstructured or difficult-to-read JSON data clearly.

Paste your JSON data into the field. Select "Format" to get a structured view with indentations, which also checks for syntax errors. Use "Minify" to remove all whitespace and breaks to make the data compact for APIs.

Validates JSON structures natively. Formats data with configurable indentation or minifies the string onto a single line, catching syntax errors with line positions.

## FAQ

### What does a JSON formatter do?

It indents JSON data so it becomes readable, or removes all whitespace (minify) to make it smaller. Invalid JSON is detected along the way.

### Can I paste API responses containing tokens?

Yes. Since nothing is sent to a server, sensitive data such as tokens or customer data stays on your computer.
