Postman Collection to cURL Converter

Postman to cURL Converter

Convert an exported Postman Collection into ready-to-run cURL commands directly in your browser. Paste the Collection v2.0 or v2.1 JSON, or upload the exported JSON file, and the converter processes every request—including requests inside nested folders. You can copy a single generated command, copy the complete result, or download all commands as a shell script or text file.

Converting one request or a full collection? Postman can display a cURL code snippet for one open request. This tool is useful when you want to convert an entire exported collection, preserve its folder structure and obtain multiple cURL commands in one operation.

How to Export Postman Requests as cURL

1. In Postman, open the collection you want to convert.
2. Use the collection menu and choose Export.
3. Select Collection v2.0 or v2.1 and save the JSON file.
4. Paste the exported JSON into this converter or upload the JSON file.
5. Start the conversion and review the generated commands.
6. Copy an individual cURL command, copy the full batch, or download it as .sh or .txt.

If you need cURL for only one request, open that request in Postman and use its code-generation or code-snippet option, then select cURL. If you need every request in a collection, exporting the collection and using this bulk converter is faster.

What Is Converted?

Postman Request to cURL Example

Assume a Postman request sends a JSON body to https://api.example.com/users, uses the POST method, includes a Bearer token and sends {"name":"Naveen"}. The generated command follows this structure:

curl --request POST 'https://api.example.com/users' \
        --header 'Authorization: Bearer YOUR_TOKEN' \
        --header 'Content-Type: application/json' \
        --data '{"name":"Naveen"}'

Replace placeholder variables and credentials before running the command. The precise formatting can differ depending on the headers, body mode and authentication stored in the collection.

Postman Variables in Generated Commands

Postman variables such as baseUrl, token or userId are preserved rather than silently replaced. This prevents the converter from guessing sensitive or environment-specific values. Before running a command in a terminal, replace unresolved variables with real values or adapt the output to read them from shell environment variables.

Authentication and Request Bodies

Bearer tokens are represented as an Authorization header, Basic authentication can be represented using -u user:password, and API keys are placed in the configured header or query string. Raw JSON and text bodies, URL-encoded fields, and multipart form-data are converted. File fields in multipart requests may still require you to confirm the local file path before execution.

Common Errors

• Invalid collection JSON: Export the collection from Postman instead of pasting a response body or an unrelated JSON file.
• Unresolved variables: Replace values such as baseUrl before running the command.
• Expired credentials: A token copied from the collection may no longer be valid.
• Incorrect file paths: Multipart file uploads must point to files that exist on the machine running cURL.
• Shell quoting differences: A command copied between Bash, PowerShell and Windows Command Prompt may require different quoting.
• Unsupported authentication: Add any custom or unsupported authorization arguments manually after conversion.

Best Practices

• Review commands before running them, especially commands that modify or delete data.
• Remove secrets before sharing a generated script with teammates or committing it to Git.
• Quote URLs and values that contain spaces or shell-special characters.
• Test one generated request before executing an entire downloaded shell script.
• Keep environment-specific URLs and credentials in environment variables where possible.

Privacy and Limitations

Conversion runs in your browser, so the collection is not intentionally uploaded for processing. Even so, handle API keys and tokens carefully and review the generated output before sharing it. The converter supports common Postman collection structures, body modes and authentication types, but Postman scripts, dynamic variables, certificates, proxy settings and some custom authentication flows may require manual changes.
