You can add an application tag to a sheet. If you prefer, you can associate data with any cell in the spreadsheet, or the cells in a column, a row, or the entire spreadsheet. The string data can be used to interact with a cell or to provide information to the application you create. The sheet data, or sheet tag, is similar to item data you can provide for the spreadsheet, columns, or rows.
Because the sheet tag is declared as an object, it is very flexible; it can be a number, a boolean, a string, or an instance of a class.
For more information on tags, refer to the Tag property in the SheetView class and the GetCellFromTag method in the SheetView class.
