Frequently Asked Questions

Everything you need to know about converting cURL to Postman collections

What is a Postman Collection?
A Postman Collection is a group of saved API requests that can be organized, shared, and executed together. It uses a structured JSON format (v2.1 schema) that includes request methods, URLs, headers, body data, authentication, and test scripts — making API development and testing much more efficient.
Why convert cURL to a Postman Collection?
Converting cURL commands to Postman format allows you to import them directly into Postman, where you can take advantage of its rich GUI for testing, documenting, and collaborating on APIs. It saves time compared to manually recreating requests and ensures accuracy.
How do I import the generated JSON into Postman?
Open Postman, click the Import button (top-left), select the Raw text tab, paste the JSON, and click Continue. Alternatively, download the .json file and drag it directly into the Postman workspace. The collection will appear in your Collections sidebar.
Which cURL options are supported?
This converter supports the most commonly used cURL flags: -X / --request (HTTP method), -H / --header (headers), -d / --data / --data-raw (request body), -u / --user (Basic Auth), -F (form data), -L (follow redirects), and --compressed.
Can I convert multiple cURL commands at once?
Currently, this tool processes one cURL command at a time and generates a single-request Postman Collection. For batch conversion, you can convert multiple commands individually and manually merge the resulting JSON arrays in the item section of a collection.
What Postman Collection version is generated?
The tool generates Postman Collection v2.1.0 format, which is the latest widely-supported schema. It includes proper URL decomposition (protocol, host, path, query parameters), structured headers, body modes (raw, urlencoded, formdata), and authentication details.
Does it support JSON, form-data, and URL-encoded bodies?
Yes! The converter automatically detects the body type based on the Content-Type header and the cURL flags used. -d with application/json produces raw JSON body, -F generates form-data, and --data-urlencode or application/x-www-form-urlencoded produces URL-encoded body.
Is my data secure when using this tool?
Absolutely. All conversion happens entirely in your browser using client-side JavaScript. Your cURL commands and API keys are never sent to any server. You can verify this by disconnecting your internet after the page loads — the tool will continue to function normally.
