Frequently Asked Questions

                

                    
How do I use this app?

                    
Enter or paste YAML text, click Format to parse and validate, then review the highlighted output. Use Clear to start over.

                    
Is this app free to use?

                    
Yes. The app is free to use and does not require an account.

                    
What happens to my input data?

                    
All processing happens in your browser. Your YAML data is never sent to any server.

                    
Why am I getting an error or unexpected output?

                    
Most issues come from invalid YAML syntax. Check indentation, quotes, and colons. Use Clear to reset and try again.

                    
Where can I find instructions and troubleshooting tips?

                    
Use the in-app Help panel. It explains inputs, options, and common mistakes, and it is usable with a keyboard including closing with Escape.
