Format, beautify, and validate JSON online. Pretty-print with 2- or 4-space indentation, fix syntax errors, and inspect nested structures instantly.
The YAML to JSON tokenizes and validates input against the relevant specification (RFC, W3C, or language standard). Syntax errors include line/column hints when the format supports positional parsing.
Input passes through a deterministic transform pipeline: normalize → validate → format/encode → output. The same input always produces identical output with no server round-trip.
Special characters, Unicode code points, and escape sequences are handled per the target format's rules. Output preserves semantic meaning while conforming to structural requirements.
