🔄 What Is JSON to cURL Conversion?

Developers often need to test APIs using curl. That usually involves manually copying JSON and wrapping it with flags like -H, -X, and -d.

But turning this:

{
  "name": "johndeo",
  "email": "formatjsononline@gmail.com"
}

Into this:

curl -X POST https://api.example.com/user \
  -H "Content-Type: application/json" \
  -d '{"name":"johndeo","email":"formatjsononline@gmail.com"}'

...can be tedious and error-prone.
