Why generated curl beats hand-written
Manually escaping a JSON body for curl means counting quotes, balancing braces inside single-quoted strings, and remembering the Content-Type header. The generator does it deterministically every time.
How to use
1. Paste the JSON body. 2. Set the URL and method (POST/PUT/PATCH). 3. Add headers (Authorization, Accept, custom). 4. Copy the generated curl line.
The output uses single-quoted heredoc-style escaping that works in bash, zsh, and most CI shells.
curl -X POST 'https://api.example.com/users' \
-H 'Content-Type: application/json' \
-H 'Authorization: Bearer $TOKEN' \
-d '{
"name": "Ada",
"role": "admin"
}'Windows and PowerShell variants
Bash escaping does not work in cmd.exe or PowerShell. The tool emits a separate variant that uses double quotes with backtick escaping for PowerShell, plus a curl.exe-friendly cmd version.
Headers and auth helpers
Common header presets: Bearer token, Basic auth, API key in header, multipart form. The tool reminds you when a body needs Content-Length or Transfer-Encoding: chunked.
Privacy
Conversion runs locally. Your JSON, URL, and headers never leave your browser.
