Excel open xml sdk - Get an empty cell

I have excel file that I need to locate a cell at.

This cell might have attributes like formatting, data validations rules etc. but no value.

I need to retrieve it even if the cell has (currently) no value since I want to maintain all the cell attributes and only set it a value.

Is it possible?

The code:

public static Cell GetSpreadsheetCell(WorksheetPart worksheetPart, string addressName)
{
    return worksheetPart.Worksheet.Descendants<Cell>().
            Where(c => c.CellReference == addressName).FirstOrDefault();
}
