Frequently asked questions
What is JSONC?
JSON with Comments — regular JSON syntax extended to allow // and /* */ comments and trailing commas, popularized by config files like VS Code's settings.json.
What does this tool do exactly?
It strips out comments and trailing commas, then parses the result as strict JSON so you get clean, standards-compliant output.
Does it support both comment styles?
Yes — both // line comments and /* */ block comments are stripped, as long as they're not inside a string value.
