JSON (JavaScript Object Notation) is a lightweight data-interchange format, much like Serializing an array, you can JSON an array which will give you a string which can then be converted back to an array for use at a later date, although this was specifically designed for use in the JavaScript library, it is now used by many programming languages and APIs for communication and storage. It is better than Serialize in some respects because it is easier to understand and modify and uses less bytes because unlike serialize the resulting string does not denote how many characters are in each field.
Our tool allows you to input your JSON string and will give you a pretty print of the object, as well as a decoded array, it will also validate your JSON string and provide any errors if it cannot decode the string.
