Dynamically adding data

New data can be added at any time with the insert() and import() methods as well as the rows() and columns() API.

Let's say you have the following formatted JSON string to import:

"[{
    'Heading 1': 'Value 1',
    'Heading 2': 'Value 2',
    'Heading 3': 'Value 3',
    ...
},
{
    'Heading 1': 'Value 4',
    'Heading 2': 'Value 5',
    'Heading 3': 'Value 6',
    ...
}]"
