Using the json formatter & validator
Paste JSON, choose format or minify, and check the result. Syntax errors are reported by the browser parser.
Real-world example
Example: {"enabled":true,"count":3} becomes indented, readable JSON.
Good to know
JSON requires double-quoted property names and does not allow trailing commas or JavaScript comments.
This tool is a planning aid, not a substitute for verifying values in vendor documentation or production configurations.
