Questions tagged [json5]

JSON5 is a superset of JSON that has a more flexible syntax. Use this tag for questions specifically related to the JSON5 standard, and NOT questions that are ONLY about regular JSON.

JSON5 is a superset of JSON that has a more flexible syntax that aligns with ES5 syntax (the version of Javascript most commonly used today). In addition to everything JSON supports, it adds:

  • unquoted property keys
  • single-quoted, escaped and multi-line strings
  • alternate number formats
  • comments
  • extra whitespace

The JSON5 reference implementation (json5 npm package) provides a JSON5 object that has parse and stringify methods with the same args and semantics as the built-in JSON object.

Can the Jackson parser be used to parse JSON5?

We'd like to parse JSON5 documents in the JVM, but the JSON5-specific libraries available on GitHub all appear to have very low support. As parsers are often magnets for security vulnerabilities, we'd prefer not to use a parser that isn't already…
