Curl to JSON Converter
Free online Curl to JSON converter. Parse cURL commands into structured JSON format or ready-to-use code snippets for Python, Node.js, PHP, and Go.
Our cURL to JSON Converter transforms cURL commands into structured JSON format or ready-to-use code snippets for multiple programming languages. Whether you are working with API documentation, debugging HTTP requests, or integrating APIs into your application, this tool streamlines your workflow by instantly converting complex cURL syntax into clean, readable output.
Why Convert cURL Commands?
cURL is the de facto standard for command-line HTTP requests, and most API documentation includes cURL examples. However, working with raw cURL commands can be challenging due to complex syntax with dozens of options and flags. You often need to translate cURL into your application's programming language, and JSON format is easier to read, share, and document than command-line syntax.
Supported Output Formats
The converter supports multiple output formats: JSON (Structured Data) showing method, URL, headers, body, and all request parameters in a hierarchical structure; Python using the popular requests library; Node.js using the built-in fetch API or axios; PHP using native cURL implementation; and Go using the standard library net/http package with proper request construction.
Supported cURL Options
The converter handles a comprehensive set of cURL options including: request method (-X, --request), headers (-H, --header), data payloads (-d, --data) including JSON and form data, form data (-F, --form), authentication (-u, --user), cookies (-b, --cookie), user agent (-A, --user-agent), follow redirects (-L, --location), insecure mode (-k, --insecure), and timeout (-m, --max-time).
How to Use This Converter
Paste your cURL command from your API documentation, browser DevTools (Network tab, Copy as cURL), or terminal. Multi-line commands with backslash continuations are fully supported. Select your output format from JSON, Python, Node.js (fetch or axios), PHP, or Go based on your needs. The converted code is generated instantly and can be copied with one click.
Common Use Cases
When integrating a third-party API, you often receive cURL examples in the documentation. Use this converter to quickly translate those examples into code you can drop directly into your application. Browser DevTools allows you to copy network requests as cURL commands. Converting these to JSON format makes analyzing the request structure, headers, and payload easier when debugging API issues.
Frequently Asked Questions
What is a cURL command and why would I need to convert it?
cURL is a command-line tool for transferring data using various protocols, commonly HTTP. Developers often receive API documentation with cURL examples. Converting cURL to JSON or code snippets makes it easier to understand the request structure, integrate into applications, or test APIs using your preferred programming language.
Which programming languages does this converter support?
This converter supports multiple output formats: JSON (structured data), Python (requests library), Node.js (fetch API and axios), PHP (cURL), and Go (net/http). Each output is ready-to-use code that you can copy directly into your project.
Does this tool handle authentication and headers?
Yes, the converter fully supports all common cURL options including: custom headers (-H), basic authentication (-u), cookies (-b), request methods (-X), data payloads (-d), form data (-F), user agent (-A), SSL verification (-k), and more. All these are properly translated to the target format.
Is my data secure when using this converter?
Yes, all processing happens entirely in your browser. Your cURL commands are parsed, converted, and never sent to any server. For sensitive API keys or credentials, the tool remains completely client-side for maximum security.
Can I convert multi-line cURL commands?
Yes. The converter handles multi-line cURL commands with backslash line continuations, which is common when copying from documentation or scripts. Simply paste the entire command as-is.
