About this tool

IconVault's JSON Formatter takes messy, minified or broken JSON and makes it readable: pretty-print with 2-space indentation, minify it back down for production, or validate it and get a plain-English error message pointing at the problem. It also loads .json files straight from your computer.

Everything runs in your browser - your JSON is parsed locally and never uploaded to any server, so API keys and payloads stay private. Every visitor gets 5 free format/minify runs (validation is unlimited); Pro members ($12/year) get unlimited runs across all IconVault tools.
