Overview
Key Features & Functionality
I don't see any documentation here or much information within the plug-in about the required data format, so I'll specify it here for those looking (including myself in the future once I forget this again)...
The plug-in expects a JSON string resulting from an array of dictionaries. Seemingly anything else will produce a hard-to-understand error. The property names of the dictionary entries will become the column names when the "header" option is enabled.
e.g.
a!toJson( { { name: "John", age: 30 }, { name: "Amy", age: 45 } } )
