cURL Command Parser

Developers share API requests as cURL commands in tickets, documentation and chat messages, but a long cURL line with many flags is hard to read at a glance. The method may be implied, headers may be scattered among flags, and the body may be buried at the end of the line. This parser reverses that process: paste a cURL command and it extracts the method, the URL, every header, and the body into clean labelled fields. It is the natural companion to code generation, because it turns a command someone else wrote back into structured information you can inspect, edit and re express in your own language. Everything runs locally in your browser. Because the output is structured rather than a single opaque line, it is also much easier to review for mistakes, such as a header that should not be shared or a body that belongs to a different endpoint, before the request is ever rebuilt or sent.

How to Use the cURL Command Parser

1. Copy the full cURL command from wherever it was shared with you.
2. Paste it into the input box on this page.
3. Click Parse cURL Command to break it into its component parts.
4. Read the method, URL, headers and body fields to understand exactly what the request does.
5. Use the parsed fields to rebuild the request in another language or to spot unwanted headers and data.

Key Features

• Method detection from explicit method flags, with GET assumed when no method flag is present.
• URL extraction that handles quoted URLs and URLs followed by additional flags.
• Header parsing that lists every header flag as a separate name and value pair.
• Body extraction from data flags, including JSON bodies, shown in full for inspection.
• Quote aware tokenising, so values containing spaces inside quotes stay together as one token.

Best Practices and Tips

• Remove line continuation backslashes before pasting if a command was split across several lines in documentation.
• Check for authorization headers in shared commands and replace real tokens before forwarding the parsed result.
• A command with no method flag is usually a GET, but a data flag often implies POST in real cURL behaviour, so read the body field too.
• Use the parsed output as a checklist when recreating a request: method, URL, headers, then body, in that order.

Common Mistakes to Avoid

• Pasting only part of a long command and wondering why a header or the body is missing from the parse.
• Assuming the first quoted string is always the URL; in some commands a header value may appear first, so verify the URL field.
• Trusting a parsed token without checking it when the original command used unusual shell quoting.

Frequently Asked Questions

What exactly does this parser extract?

It extracts the HTTP method, the request URL, all headers supplied with header flags, and the request body supplied with data flags. Flags that do not affect the request itself, such as silent mode, are ignored, because the goal is a readable summary of what the request does.

Does it handle multi line commands?

Commands copied from documentation often use backslash line continuations. Joining the lines into one line before pasting gives the most reliable parse, and this page treats newlines as whitespace so simple wrapped commands still parse.

What if the method is not stated?

cURL defaults to GET when no method is given, unless a data flag is present, in which case it defaults to POST. This parser follows the same rule and reports the inferred method, so the output always shows a method.

Is the parsed command executed?

No. Parsing only reads the text and displays its parts. No network request is made, which makes it safe to inspect commands for unknown endpoints or sensitive headers.
