I'm trying to load an Excel document into Alteryx, and one of my columns is giving me a hard time. The first few rows are dates, so that's the data type Alteryx assumes for that column. There is other data further down in the column that is just plain text data. Instead of bringing in that text, Alteryx shows [NULL] in those cells. Is there anyway I can get Alteryx to import those text fields even though Alteryx is assuming that the whole column is dates?
