Common questions about the JSON Formatter.

                    


        

                            

                    
                    

                        

                            
Yes. Use the file upload below the input area to load a .json file, then format, minify, or validate it. Files are read locally in your browser.

                        

                    

                

                            

                    
                    

                        

                            
Format adds readable indentation (2 spaces, 4 spaces, or tabs) and optional key sorting. Minify removes all whitespace to produce the smallest valid JSON string.

                        

                    

                

                            

                    
                    

                        

                            
Yes. Validate, format, and minify all parse your input first. Syntax errors display the parser message so you can fix the line before re-running.
