Defines how a cell will be exported to Excel.
|Value||0||The cell will be converted to what it represents. For example, the string "1/1/2000" will be entered as a date.
|Text||1||Whatever you have in the grid, will be exported as a string to Excel.
Numeric format will be preserved, but the Excel cells will contain strings, never numbers. Those strings can't be used in formulas, for example the sum of a range containing strings with numbers will always be 0.
|Html||2||The cell contains HTML formatted text, and will be entered in Excel as rich text.
|Formula||3||The cell contains a formula.
