JSON Formatter Tool Introduction
JSON is a data structure that replaces XML, and it's not worse than XML in terms of description. JSON is just a string, but elements will use specific symbols to mark:
- {} Double braces represent objects
- [] Square braces represent arrays
- "" Double quotes contain properties or values
- : Colon indicates that the latter is the value of the former (this value can be a string, number, or another array or object)
For example, {"name": "Tom"} can be understood as an object containing a name of Tom, and [{"name": "Tom"}, {"name": "Jerry"}] represents an array containing two objects.
Common Questions and Answers
- Why does {name:'json'} fail validation?
- According to the official JSON specification, if it's a string, both keys and values should be quoted with double quotes, so the correct format should be {"name":"json"}.
