Free cURL to Code Converter

How to use the cURL converter

1. Paste the cURL command into the input box. You can include line continuations (\ at the end of a line).
2. Choose a target language. Python, JavaScript (fetch or axios), PHP, Go and Ruby are supported.
3. Click Convert. The generated code appears on the right.
4. Copy or download. Use the Copy button for the clipboard, or Download to save a file with the correct extension.

What this converter handles

• Request method with -X / --request, or inferred from -d, -F or -I.
• URLs supplied as the final argument or with --url.
• Headers with -H / --header, including duplicate header names.
• JSON and raw bodies with -d, --data, --data-raw, --data-binary and --json.
• URL-encoded bodies with --data-urlencode.
• Multipart forms with -F / --form, including text fields and file fields (@file).
• Basic authentication with -u / --user.
• Cookies with -b / --cookie.
• Proxy configuration with -x / --proxy.
• Redirect control with -L / --location and --no-location.
• Insecure TLS with -k / --insecure (where the target language supports it).
• Compressed responses with --compressed (adds an Accept-Encoding header).
• User-Agent and Referer shortcuts with -A and -e.

Supported flags

Examples

JSON POST to Python requests

Input:

curl -X POST 'https://api.example.com/v1/users' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer YOUR_TOKEN' \
  -d '{"name":"Ada Lovelace","email":"ada@example.com"}'

Output (Python):

import requests

url = "https://api.example.com/v1/users"

headers = {
    "Content-Type": "application/json",
    "Authorization": "Bearer YOUR_TOKEN",
}

data = '{"name":"Ada Lovelace","email":"ada@example.com"}'

response = requests.request("POST", url, headers=headers, data=data)

print(response.status_code)
print(response.text)

Multipart form to JavaScript fetch

Input:

curl -X POST 'https://api.example.com/upload' \
  -F 'name=report' \
  -F 'file=@/path/to/report.pdf'

The fetch output uses a FormData object. The file path is kept as a comment because a browser cannot read a local path directly; you must supply a File object from an <input type="file"> element.

Limitations to know

• Shell parsing is not identical to every shell. The tokenizer handles POSIX-style single and double quotes, backslash escapes and line continuations. PowerShell and Windows cmd quoting rules differ; commands copied from those environments may need adjustment.
• Not every cURL flag is converted. Flags such as -o, -i, -v, --trace, --retry and -T are either ignored or warned about. Unsupported flags are listed in the warning area rather than silently dropped.
• Browser fetch cannot disable TLS verification. The -k flag is represented in Python, PHP, Go and Ruby, and in Node.js axios, but not in browser fetch(). The generated code notes this limitation.
• Multipart file paths are not portable. A cURL command can read a local file with @/path/to/file. Generated code must use the platform’s file API or a file input, so the path is preserved as a comment where appropriate.
• Duplicate headers are preserved in the generated code where the language supports arrays, but some libraries combine them into a single comma-separated value. Check the final behavior if your API depends on duplicate headers.
• This tool does not execute the request. It only generates code. You are responsible for reviewing the output and adding error handling, timeouts and logging.
