FAQ

            

                            
Common questions about the YAML Formatter.

                    


        

                            

                    
                    

                        

                            
Yes. Use the To JSON button to parse your YAML and output equivalent JSON. This is useful when migrating config files or API payloads.

                        

                    

                

                            

                    
                    

                        

                            
The tool accepts .yaml and .yml files. Uploaded content is read in your browser and never sent to a server.

                        

                    

                

                            

                    
                    

                        

                            
Click Validate or Format — invalid YAML shows a parser error with the problem location. Common issues are inconsistent indentation and unquoted special characters.
