Property Value

Type	Default	Description
Boolean	false	true to export empty strings as blank cells; false to export empty strings as empty string values.

Remarks

In XLS and XLSX file formats, empty cell values can be displayed as empty strings or as blank (null) cells.

The grid exports empty strings in XLS and XLSX formats as non blank values and the ISBLANK Microsoft Excel function for these cells returns false. Set the SuppressEmptyStrings property to true to export empty strings as null values. In this case, the ISBLANK function for these cells returns true.
