JSON Formatter
Paste JSON, format or minify it, catch syntax errors before they bite you elsewhere.
Paste JSON, format or minify it, catch syntax errors before they bite you elsewhere.
Paste JSON into the box, then click Format (pretty-printed with 2-space indent) or Minify (all on one line). Invalid JSON shows a clear error message instead of silently failing.
You'll see a message describing what's wrong, instead of the box just staying blank or showing nothing.
No - it validates against strict JSON via the browser's own JSON.parse, so comments or trailing commas will show as errors.
No, formatting and validation both run entirely in your browser.
