Paste YAML to get JSON (or vice versa). Indentation matters in YAML, so invalid documents are reported with the line number. JSON keys, arrays and scalars map 1:1.

Frequently asked questions
Why is YAML indentation so important?
YAML uses indentation (not braces) to express nesting. A single misaligned space can change meaning or cause a parse error.
How are numbers preserved?
Integers, floats, booleans and null stay typed through conversion; strings are quoted where needed to keep types stable in JSON.
