Paste JSON and choose Format or Minify. Everything runs within your browser.
Good to know
Format, minify, and validate JSON instantly without uploading your data. Check the resulting output before using it in production.
Frequently asked questions
Does my JSON get uploaded?
No. Formatting and validation use the browser's native JSON functions.
Does this rearrange data?
Formatting only changes whitespace and keeps object keys in their input order.
