Common questions about this tool

Yes. You can import a local CSV file into the input panel and the tool converts it with the same parser used for pasted CSV text.

Use path-style headers such as user.name or items[0].sku to map a row into nested objects or arrays, and valid JSON object or array cells are also preserved as nested values.
