This extension adds a "Paste cURL as <language>" option to the right click menu when you're editing a Python, JavaScript, PHP, R, Go, Java, Rust or JSON file.
The JSON output is not in any standard format, you can think of it as curlconverter's parser's internal state.
The version of curlconverter is much older than the one on https://curlconverter.com due to a technical limitation of VS Code.
