New Post: Exception when creating or loading workbook: When using relative paths, make sure the current directory is correct.

I was finally able to display dates out of OpenXML, which reminds me-- I'm amazed that you have written your ClosedXML library with so much functionality given the documentation and the difficulty of simple operations in OpenXML! It seems to me that most of the examples for OpenXML involve creating worksheets, not extracting data from them.
