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.
