"Copy as cURL" is the fastest way to capture a request exactly as the browser sent it — the URL, method, every header and the body — but curl syntax is not something you can paste into a C# project. Translating it by hand means untangling shell quoting first: bash single quotes and $'…' strings, Windows cmd's ^ escapes in Chrome's cmd variant, or PowerShell backticks. Then each curl flag has to be mapped onto the target library correctly. -d implies POST and a form-urlencoded body, -G moves that data into the query string, -F builds multipart form data, -u is basic authentication, and --compressed means the client must decompress the response. In .NET there are extra traps: content headers must live on HttpContent, a manually set Cookie header is ignored unless the cookie container is turned off, and a new HttpClient per request exhausts sockets. This converter parses the command with the same quoting rules as the shell it came from, builds a neutral description of the request, and generates idiomatic code for C# HttpClient, JavaScript fetch, Node axios, Python requests, PHP cURL and Go net/http — with anything that could not be translated listed instead of silently lost.
Reading the command
The input style is detected from its line continuations (\, ^ or `) and quoting. bash input supports single, double and $'…' ANSI-C strings; cmd input is un-escaped the way cmd.exe does and then split with the Windows argument rules, so Chrome's \^" sequences come out as plain quotes; PowerShell input supports '' and backtick escapes. Only the first command of a chain (&&, |, ;) is used, and you are told when that happens.
Understanding curl options
Long and short options are both read, including combined flags like -sSL, attached values like -XPOST and --opt=value. -d, --data-raw, --data-binary, --data-urlencode and --json follow curl's own rules for methods, content types and @file references, -G builds the query string, -T uploads a file with PUT, and credentials in the URL become basic authentication.
Generating C#
The C# output uses a single static HttpClient, an HttpRequestMessage with the right HttpMethod, TryAddWithoutValidation for browser headers such as sec-ch-ua that would fail strict validation, content headers on the content, FormUrlEncodedContent or MultipartFormDataContent where appropriate, AutomaticDecompression for --compressed, UseCookies = false when a Cookie header is present, and EnsureSuccessStatusCode.
Credentials
Authorization, Cookie and API-key style headers, basic-auth passwords, token-like query parameters and password-like form or JSON fields are detected. With redaction on (the default) their values are replaced before code is generated, and the share link is built from a redacted curl command reconstructed from the parsed request — never from your original paste.
