JSON Formatter: Format and Validate Syntax

How to use this tool

Paste JSON, choose an indentation style, then format or minify it. The validator checks whether the text can be parsed as JSON.

Limits and safe use

Syntax validation does not verify a schema, business rules, or whether values are safe to use. Avoid pasting confidential data into any web utility; use local tooling for sensitive payloads.
