About JSON Formatting

Indentation:

  • 2 spaces: Small, efficient, hard to read
  • 4 spaces: Standard, readable, takes more space
  • Minify: Production-ready, debugging nightmare

Why your JSON is broken:

Most common culprits:

  • → Trailing comma (last item in array/object has a comma)
  • → Single quotes instead of double quotes
  • → Unquoted keys (name instead of "name")
  • → Copy-paste chaos (random extra/missing commas)

Paste your JSON, we'll tell you what's wrong.
