JSON Formatter and Validator

Check JSON syntax, add readable indentation, or create a compact representation.

What the JSON formatter does

The tool parses your document with the browser JSON engine. Valid input can be displayed with two-space indentation or reduced to a compact single line. Invalid input produces a useful syntax error.

Handling sensitive data

Processing takes place locally. Even so, avoid pasting secrets into tools on public or shared devices.
