Working with excel files
You must adhere to the rules that are contained there
You can't even hide rows so that they are imported properly.
My advice is format your tables properly on the first page, then put the description information on the second page.
When you import the table, you will be able to use the first page.
Exporting to another format prior to bringing (ie csv etc) won't fix the problem... the problem is the way that the data are set up in Excel... a bigger problem is that Excel is being used as a database management system.
