Pretty-print JSON

APIs fail on a trailing comma or a smart quote from a docs site. Pretty-print the payload locally, then minify if you need a single line.

Validate first

Paste into the JSON Formatter. If it throws, the line number is the start of the hunt — often a missing comma above. Do not “fix” production by guessing in a chat window.

Minify vs pretty

Pretty is for humans. Minified is for logs and some size-sensitive posts. Keep secrets out of screenshots. Wordnio formats in the browser.

Steps

  1. Paste the payload.
  2. Pretty-print and fix the first error.
  3. Copy the valid JSON back to your editor.
