Developer FAQ

Questions about local clipboard conversion on Mac

How do I convert copied JSON to Swift Codable on Mac?

Copy the JSON, open its actions in Pasteon, and choose Generate Data Model followed by Swift Codable. Pasteon generates the model locally and returns code ready to copy or paste.

Can Pasteon convert cURL to URLSession, fetch, and Axios?

Yes. Copy a supported HTTP or HTTPS cURL command, open Convert cURL Request, and choose URLSession, fetch, or Axios as the output.

Does Pasteon upload copied API data to an online converter?

No. Pasteon clipboard history and its bundled JSON and cURL conversions run locally on your Mac. Review any custom Workflow script before enabling it, especially if it performs network requests.

Which variable naming formats can Pasteon generate?

Pasteon can turn copied words into common naming styles such as camelCase, PascalCase, snake_case, and kebab-case.
