About the JSON Formatter

What does the JSON Formatter do?
Format, validate, and minify JSON. GeekTool runs the JSON Formatter entirely in your browser — input never leaves your device.
Is the JSON Formatter free?
Yes. The JSON Formatter is part of GeekTool, a free suite of 50+ developer utilities. No sign-up, no ads inside the tool, no quotas.
Does the JSON Formatter send my data to a server?
No. All processing is client-side JavaScript. Your input stays in your browser tab — we never see it.
