问题 Ok - so I realized that after writing some code and figuring out stuff, that jxl does not support xlsx, only POI (XSSF). Ok fine. What I am trying to do is search for a cell with a string value "Result" in a specified column. Once I find that, then as a test passes or fails, it writes "Pass" or "Fail" in the cell that is blank.
