It is very strange. It will only read in the first cell. The input tool will not read in any of the headers or the data. If I open the xls (97-2003 excel) file in Excel, it opens and reads just fine. If I have the file open in Excel and then I run the input tool and the browse tool in Alteryx, it does work! But only if the file is already open in Excel. This is not a valid solution. What am I missing?
