  2. 2Validation runs automatically as you type — no submit button needed. Watch the status badge in the top-right of the input panel.
  3. 3If your YAML is valid, the formatted output with consistent 2-space indentation appears in the right panel instantly.
  4. 4If there is a syntax error, the right panel shows the error message with the exact line and column number so you can fix it quickly.
  5. 5Once your YAML is valid, click 'Copy' to copy the formatted output to your clipboard. Use 'Reset' to start fresh with a blank editor.
