FAQ

                

                    What is a JSON formatter?
                    
A JSON formatter adds indentation and line breaks to JSON data, making it easier to read, understand, and edit.

                

                

                    What does JSON validation check?
                    
JSON validation checks whether the input follows valid JSON syntax, including correct quotation marks, commas, brackets, braces, keys, and values.

                

                

                    What is the difference between formatting and minifying JSON?
                    
Formatting makes JSON easier to read by adding spaces and indentation. Minifying removes unnecessary whitespace to reduce the size of the JSON data.

                

                

                    What errors can the Fix common errors button repair?
                    
It can help repair common mistakes such as single quotes, trailing commas, unquoted property names, and other simple JSON syntax issues. Some complex errors may still require manual correction.

                

                

                    Can JSON contain comments?
                    
No. Standard JSON does not support comments. Comments must be removed before the data can be parsed as valid JSON.

                

                

                    Is my JSON uploaded to a server?
                    
No. All formatting, minifying, validation, and error fixing are performed directly in your browser. Your JSON data never leaves your device.
