Cell Customization

The customizeCell function allows you to modify cell data and value formatting in exported worksheets. You can access and change the following attributes:

Font properties
Cell background
Cell values
Text alignment
Formatting properties

The customizeCell function also allows you to identify row types. For example, this demo changes the background color and font weight for cells with the "group" rowType.

You can specify the cell used as the start position for exported data. For this purpose, assign an object with the cell coordinates to the topLeftCell property.
