Frequently asked questions

What is JSONC?

JSONC is JSON with comments, used by config files like tsconfig.json and VS Code settings. Standard JSON parsers reject its comments and trailing commas.

Does it protect strings?

Yes. Comment markers and commas inside string values are ignored, so URLs like http://example.com and comment-like text inside strings are preserved.

Is the output validated?

Yes. After stripping comments and trailing commas the tool parses the JSON, so invalid input produces a clear error instead of broken output.
