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 Groovy java.net.http code appears instantly.
Set up: Install Groovy 3 or later on Java 11 or later. No libraries are needed.
Run it: Save the code as request.groovy and run groovy request.groovy. Replace placeholders such as YOUR_TOKEN first, and check any notes under the editors for curl options that have no java.net.http equivalent.

Example

GET with headers → Groovy java.net.http

curl command

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

Groovy java.net.http

import java.net.http.HttpClient
import java.net.http.HttpRequest
import java.net.http.HttpResponse

def client = HttpClient.newHttpClient()
def request = HttpRequest.newBuilder(URI.create('https://api.example.com/v1/users?page=2'))
    .header('Accept', 'application/json')
    .header('Authorization', 'Bearer YOUR_TOKEN')
    .method('GET', HttpRequest.BodyPublishers.noBody())
    .build()

def response = client.send(request, HttpResponse.BodyHandlers.ofString())
println response.statusCode()
println response.body()

Converting curl to Groovy java.net.http

The Groovy code uses java.net.http.HttpClient, the HTTP client built into Java 11 and later, so it runs without extra dependencies. Strings are single-quoted, so $ in URLs or tokens isn't treated as interpolation.

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 java.net.http code. Options that have no java.net.http equivalent are listed under the editors rather than silently dropped.

Limitations

java.net.http has no multipart helper, so file uploads are built by hand in the code.
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

Why single-quoted strings?

Double-quoted Groovy strings are GStrings: $name inside them is replaced with a variable. Single quotes keep values such as tokens exactly as written.

Does this work in a Jenkins pipeline?

In a sandboxed pipeline, these Java classes may need script approval. The HTTP Request plugin's httpRequest step is an alternative there.

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.
