常见问题
›What is JSON5?
A superset of JSON that allows comments, trailing commas, unquoted keys and a few other conveniences. It's the format of many config files (tsconfig, devcontainer, babel) and drift-prone hand-edited JSON.
›Does it handle single-quoted strings?
This tool handles the most common JSON5 drift — `// comments`, `/* block comments */` and trailing commas. For the full JSON5 spec (unquoted keys, single quotes, hex numbers) paste into a proper JSON5 parser locally.
›What does the output look like?
Strict, spec-compliant JSON — 2-space indented. Safe to feed to any JSON.parse or schema validator.
›Is it free?
Yes — fully free, in-browser, no signup.
