Get more from Curl Converter
Curl Converter translates a curl command into request code for supported programming languages and libraries. A curl invocation can describe a method, headers, body, authentication, and target URL. Converting it provides a starting point for application code, but the generated request still needs error handling, timeouts, and integration with the application's credential management. Code transformations are most useful when you know the language and the surrounding context of the snippet. Work from a saved copy and start with a small, valid example that demonstrates the behavior you need. Formatting, encoding, and generation do not establish that a program is correct. Review the output as source code, keep meaningful comments when appropriate, and test the result in the same environment that will eventually interpret it. This makes subtle changes much easier to spot.

How to use this tool
- Paste a small, representative snippet and keep a copy of the input. Include the punctuation and delimiters needed to make the example meaningful.
- Paste a representative curl command, select the target language, and compare the method, headers, URL, and body in the generated code.
- Review the example below and compare its expected behavior with a small sample of your own input before continuing.
- Copy the result into a scratch file and verify it with the intended parser, editor, or test environment before replacing the original code.
SEE IT IN PRACTICE
A worked example
curl https://example.com/status
Request code for an HTTP GET to https://example.com/status
The generated language-specific code represents the request; conversion does not require the endpoint to return a particular response.
A request consists of several independent parts
Review the method, complete URL, headers, authentication, body, and content type separately. A generated snippet can look plausible while placing the payload in the wrong representation or omitting a header required by the endpoint. Shell quoting in the curl input is another layer: the quoted command should describe the bytes you intend to send. Begin with a simple GET, then add a small JSON body or authentication placeholder so changes can be compared clearly.
Generated request code needs application handling
A curl-to-code conversion does not supply a complete integration. The application still needs timeout behavior, error handling, retry decisions, response validation, and appropriate secret management. Do not paste a real bearer token from a diagnostic command into public example code. Keep request generation separate from sending the request, and test only against an endpoint you are authorized to use. When the generated language uses a particular library, verify that library's parameter names and behavior in your actual project environment.
When this tool is useful
- Turn an API documentation example into application code
- Compare request syntax across languages
- Review the components of a captured curl command
Tips for a better result
- Check authentication placement, content type, payload encoding, and redirects before testing the request against an endpoint you control.
- Separate a syntax check from a behavior check. A snippet can parse successfully while producing the wrong value, selecting the wrong element, or changing an important edge case.
- Keep the source and the settings used for this result together. That makes a later comparison or correction easier, especially when another person needs to reproduce the same outcome.
Frequently asked questions
What should I remove before sharing a curl example?
Replace real tokens and cookies with placeholders before sharing examples. Shell quoting and binary request bodies may require additional manual work in the target language.
Can I use generated or transformed code immediately?
Treat the result as a draft to review. Check names, escaping, syntax, and assumptions in the target environment, then run a representative test. The tool cannot see the wider application or know every requirement that applies to it.
How do I investigate unexpected output?
Reduce the input to the smallest example that still shows the issue. Check the chosen language or mode, inspect special characters and whitespace, and compare with the original. Add complexity back gradually after the basic example works.
What happens to the information I enter?
The utility processes your input in this browser. Some tools retain field values in browser storage or the URL; avoid entering secrets in shareable fields. Page and asset requests still go to the hosting provider. Read the privacy and offline-use notes for details.
