About this tool
A no-nonsense JSON formatter for API payloads, config files, and LLM outputs. Paste in ugly JSON and get a clean, indented version — or a minified one for embedding.
How it works
- Paste JSON into the editor.
- Choose Format for a pretty-printed 2-space version, or Minify to strip whitespace.
- Invalid JSON shows an inline error with the approximate line number.
When to use it
- Cleaning up LLM-generated JSON before parsing it in production.
- Preparing config snippets for docs and blog posts.
- Quick sanity check on a webhook payload.
