FAQ

Questions JSON5 owners ask.

  • 01

    What makes this different from JSON.parse()?

    JSON.parse() rejects trailing commas, comments, single quotes, and unquoted keys. JSON5 accepts all of these and outputs strict RFC 8259 JSON.

  • 02

    Does it support JavaScript-style comments?

    Yes. Both single-line (//) and multi-line (/ /) comments are supported and stripped from the output.

  • 03

    Can it handle unquoted object keys?

    Yes. {name: 'Alice'} is valid JSON5 and will be converted to {"name": "Alice"} in the strict output.
