Excel accepts expressions like:
```
IF(3="","a","b")
```
Where the comparison obviously returns false. ClosedXML tries to convert the empty string to an integer, fails, and cause an exception.
In attachment, an example of a file that is displayed by Excel, but throws an exception when read with a "cell.Value" in ClosedXML.
