I have a column called "Invoice Label." The rows consist of mixed alpha-numeric characters that powerpivot correctly imports as text. I also have another column called "Invoice ID." The records in this column consist of a mix of either all numbers or alpha-numeric characters. Powerpivot reads the second column as all number and does not import the records that are a mix of alpha-numeric characters. Can I format this column such that it imports properly? I don't need to perform calculations on the field but I do need for it to be included in my resulting pivot table results.
