Frequently asked questions
What extra syntax does JSON5 allow that JSON doesn't?
Comments, unquoted object keys, single-quoted strings, trailing commas, and a few other relaxed conventions meant for hand-written config.
Why would I need to convert JSON5 to JSON?
Many APIs and tools only accept strict JSON — this lets you author config comfortably in JSON5 and produce standards-compliant JSON for them.
Are comments preserved in the output?
No — since strict JSON has no comment syntax, comments are dropped during conversion.
