JSON Formatter guide
Format and minify JSON locally. Clear error messages for invalid payloads — ideal for configs, API bodies, and CI snippets.
Open toolPrivacy
For supported workflows, files are processed locally in your browser and are not uploaded to SnapTools servers.
Overview
Validate JSON, pretty-print with indentation, or minify for production payloads — all locally in your browser.
Great for cleaning config exports, API bodies, and CI snippets before you paste them into dashboards.
How it works
We JSON.parse your input, then JSON.stringify with pretty indentation or without whitespace — errors surface with the parser message.
Benefits
Ship cleaner configs to teammates and catch trailing-comma mistakes before CI blocks a deploy.
Security & privacy
Text never leaves your tab; still redact tokens before pasting into any shared screen recording.
