I encountered a similar problem in the past also and found the solution to be the same: force the test data to text so TestComplete will interpret it as a string. But also, my understanding is that setting Excel pages or columns to be of type text still does not guarantee that TestComplete will interpret a cell value as a string. The only way to force this reliably is to precede the value in the cell with a ' (single quote). So Kyle could force the test data to text this way instead of using .csv file if Excel is preferable.
