Overview

The cURL Command to HAR Converter allows you to instantly transform raw cURL commands into portable HAR 1.2 request entries offline. It parses headers, cookies, basic authentication, query parameters, and request bodies without executing network requests or reading local file contents.

When to use

When you need to import a cURL command into API testing tools like Postman or Insomnia that accept HAR files.
When you want to document or share an HTTP request structure in a standardized HTTP Archive (HAR) format without executing the request.
When you need to safely parse sensitive cURL commands containing credentials or cookies into structured JSON logs without sending network traffic.

How it works

1Paste your raw cURL command into the input text area.
2Toggle the option to include a creator comment in the output metadata if desired.
3The parser extracts the HTTP method, target URL, headers, query parameters, cookies, and request body offline.
4Copy the generated HAR 1.2 JSON log entry to use in your API clients or documentation.

Use cases

Generating HAR files to import complex cURL commands into API clients like Postman or Insomnia.
Documenting API requests in a standardized HTTP Archive format for developer portals.
Converting terminal-based cURL examples into structured JSON logs for debugging and archiving.

Examples

1. Convert JSON POST Request with Authentication

API Developer

Background

An API developer needs to import a complex cURL command containing basic authentication and a JSON payload into a tool that only supports HAR imports.

Problem

Manually recreating the headers, query parameters, and JSON body in the target tool is time-consuming and error-prone.

How to use

Paste the cURL command with the -u and -d flags into the input field and click convert.

curlCommand: curl -X POST 'https://api.example.com/users?source=demo' -H 'Content-Type: application/json' -u demo:secret -d '{"name":"Ada"}'
includeCreatorComment: true

Outcome

A valid HAR 1.2 JSON object containing the parsed method, URL, basic auth header, query parameters, and JSON postData.

2. Convert cURL with Cookies and Custom Headers

QA Engineer

Background

A QA engineer wants to save a session-specific cURL command from a browser console as a reusable HAR entry.

Problem

The cURL command contains sensitive session cookies and custom headers that need to be structured into a standard HAR format.

How to use

FAQ

Does this tool send my cURL request over the network?

No, the conversion is performed entirely offline. The tool parses the command syntax without executing any network requests.

How are local file uploads in cURL commands handled?

File references (such as @file.txt) are recorded as filenames only. The tool does not read or upload your local file contents.

Can I convert multiple cURL commands at once?

The converter parses one cURL command at a time into a single HAR 1.2 log entry.

Are cookies and basic authentication headers preserved?

Yes, cookies, basic authentication, and custom headers are parsed and represented in the resulting HAR headers and cookies arrays.

What version of HAR does this tool generate?

The tool generates standard HAR 1.2 formatted JSON log entries.

curlCommand: curl https://api.example.com/data -H 'Cookie: session=abc123' -H 'X-Custom-Header: value'
