Quick Examples

Pick an example, then press Use This Example

GET Request

curl -H 'Accept: application/json' https://api.example.com/users

Copy any request as cURL

1Open your browser's DevTools and go to the Network tab.
2Right-click (or Ctrl-click) the request you want.
3Choose Copy → Copy as cURL (in Chrome pick the bash version).
4Paste it into the Enter cURL Command box above.

This works in Chrome, Edge, Firefox and Safari.

Careful: copied commands often contain cookies or tokens. Remove them before sharing the code — sharing a session cookie is like sharing your password. Conversion happens entirely in your browser.

How to use this tool

Copy a curl command — from API documentation, or from your browser's DevTools (Network tab → right-click a request → Copy as cURL (bash)).
Paste it into Enter cURL command. The VB.NET HttpClient code appears instantly.
Set up: Install the .NET SDK 6 or later. Create a project with dotnet new console -lang VB.
Run it: Put the code in Program.vb and run dotnet run. Replace placeholders such as YOUR_TOKEN first, and check any notes under the editors for curl options that have no HttpClient equivalent.

Example

GET with headers → VB.NET HttpClient

curl command

curl 'https://api.example.com/v1/users?page=2' \
  -H 'Accept: application/json' \
  -H 'Authorization: Bearer YOUR_TOKEN'

VB.NET HttpClient

Imports System
Imports System.Net.Http

Module Program
    Sub Main()
        Dim client As New HttpClient()

        Dim request As New HttpRequestMessage(HttpMethod.Get, "https://api.example.com/v1/users?page=2")
        request.Headers.TryAddWithoutValidation("Accept", "application/json")
        request.Headers.TryAddWithoutValidation("Authorization", "Bearer YOUR_TOKEN")

        Dim response = client.Send(request)
        Console.WriteLine(CInt(response.StatusCode))
        Console.WriteLine(response.Content.ReadAsStringAsync().Result)
    End Sub

Converting curl to VB.NET HttpClient

HttpClient is .NET's built-in HTTP client. The VB.NET code builds an HttpRequestMessage, sends it with client.Send and prints the status and body.

The converter reads the curl command the way curl does — the method (-X), headers (-H), request bodies (-d, --data-raw, --json, -F), query strings, basic auth (-u) and cookies — and writes the equivalent HttpClient code. Options that have no HttpClient equivalent are listed under the editors rather than silently dropped.

Limitations

The code is a starting point: add timeouts, retries and error handling for production use.
Secrets in the curl command are copied into the code — move them to environment variables before committing.

Frequently asked questions

How are line breaks written in VB strings?

VB strings have no escape sequences, so the code joins vbLf, vbCr, vbTab and ChrW(n) with &. Quotes are written as "".

Should I use Async/Await?

In an application, yes: mark the method Async and use Await client.SendAsync(request). The example uses Send to stay short.

Is my curl command sent to a server?

No. The conversion runs entirely in your browser, so tokens and passwords in the command never leave your device. Still, replace real secrets before sharing the generated code.
