Analizar JSON5 — JSON with relaxed syntax
JSON5 extends JSON con comments, trailing commas, unquoted claves, single quotes, y más. Aprender el syntax extensions y conversión a estándar JSON.
- 1
JSON5 allows: single-quoted strings, unquoted object keys (if they are valid identifiers), trailing commas, comments (// and /* */), hexadecimal numbers, Infinity/NaN, and multi-line strings. It is useful for configuration files where human readability matters.
- 2 Formateador JSON →
Paste JSON5 content and format it as standard JSON. This strips comments, converts single quotes to double quotes, quotes all keys, and removes trailing commas — producing valid JSON that any parser can read.
- 3 Validador JSON →
Validar the converted JSON to ensure it is syntactically correct. JSON5 features that were stripped (comments, trailing commas) do not appear in standard JSON — verify nothing was lost in conversion.

JSON5 is primarily for human-authored configuration. Never use it for data interchange — standard JSON is universally supported. Convert JSON5 to JSON at build time, not runtime, to avoid shipping a JSON5 parser to the client.
Preguntas frecuentes
- Is JSON5 a replacement for JSON?
- No. JSON5 is a superset of JSON for human-authored files (configs, fixtures). For data interchange (APIs, storage), use standard JSON — it is universally supported and has no parser ambiguity.
- Can I use JSON5 in my build tool?
- Yes. Many tools (Vite, ts-node, Babel) support JSON5 config files. They parse JSON5 at startup and convert to JSON internally. Check your tool's documentation for JSON5 support.
