Filter Selection dialog appears on the screen.
Workaround: Open the file with Excel and save it as a new document.
Add support for Hidden and Empty Cells options:
When the worksheet contains fraction numbers with fractional parts > 0.5 and < 0.5 and both these numbers have fraction format applied, the number with fractional part < 0.5 will have incorrect whole part.
The row declaration is the following: <row r="8" spans="1:18" ht="15.75" x14ac:dyDescent="0.25"> The dyDescent attribute is described as follows: The dyDescent attribute is a double attribute, as specified in [XMLSCHEMA2/2] section 3.2.5, that specifies the vertical distance in pixels from the bottom of the cells in the current row to the typographical baseline of the cell content if, hypothetically, the zoom level for the sheet containing this row is 100 percent and the cell has bottom-alignment formatting. See section 184.108.40.206 for how this element integrates with the Office Open XML file formats specified in [ISO/IEC29500-1:2016]. The dyDescent attribute has a side effect; it sets the customHeight attribute to true even if the customHeight attribute is explicitly set to false. Note: Since the dyDescent attribute is not implemented, the height is not recognized to be custom and therefore it is not imported at all. The row has the default height.
When the workbook contains multiple styles (e.g. 50000), the import is extremely slow. MS Excel loads this document instantaneously.
When inserting cells a check is performed for data loss. This check should take into account the value property, but should not take into account properties like cell value format and data validation. Workaround: clear the values at the end of the worksheet before inserting cells. worksheet.Cells[1048575, 0, 1048575, 16383].ClearDataValidationRule();
When the scale factor of a document is smaller, the borders don't seem to scale correctly when exported to PDF. They appear much thicker than they would when exported from Excel.
