How to use the YAML to JSON Converter (and JSON to YAML)

                    
    
                                                    
  1. 
                                1
                                
    Choose YAML → JSON or JSON → YAML.
    
                            
    2.

    Paste your file; the result updates as you type, and errors show the line.

Frequently asked questions

                    

                                                    

                                
                                    Why does my YAML fail to convert?
                                    
                                
                                
Usually indentation (YAML needs spaces, not tabs), a missing space after a colon, or an unquoted value containing ": ". The error shows the line.

                            

                                                    

                                
                                    Are comments kept?
                                    
                                
                                
No. JSON has no comments, so comments in YAML are dropped when converting.
