About JSON Formatting

                    

                    

                        
JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate.

                        
Proper formatting improves readability with consistent indentation and structure, while validation ensures your JSON follows the correct syntax rules.
