    JSON Helper

    Provides methods for working with data in JavaScript Object Notation (JSON) format.

    • Expecting 'STRING' - You probably have an extra comma at the end of your collection. Something like { 'a': 'b', }
    • Expecting 'STRING', 'NUMBER', 'NULL', 'TRUE', 'FALSE', '{', '[' - You probably have an extra comma at the end of your list. Something like: ['a', 'b', ]
    • Enclosing your collection keys in quotes. Proper format for a collection is { 'key': 'value' }
    • Make sure you follow JSON's syntax properly. For example, always use double quotes, always quotify your keys, and remove all callback functions.

    Json Helper For Applescript

    If you use a Windows computer you may end up with different results. This is possibly due to the way Windows handles newlines. Essentially, if you have just newline characters (n) in your JSON and paste it into JSONLint from a Windows computer, it may validate it as valid erroneously since Windows may need a carriage return (r) as well to detect newlines properly. As a solution, either use direct URL input, or make sure your content's newlines match the architecture your system expects!
