Frequently Asked Questions

How do I validate JSON syntax?

Paste your JSON into the formatter. If it's invalid, the tool highlights the error location and explains what's wrong (missing comma, unclosed bracket, etc.).

What is the difference between minified and formatted JSON?

Minified JSON has no whitespace and is compact for transmission. Formatted JSON has indentation and line breaks for human readability. Both are functionally identical.
