Fix import of orders via csv file
BUG: CSV order import doesn't support standard ascii characters in column headers.
If you have a column header named "P.O. Number:" in your csv file you can upload the file and create the mapping just fine but when you go to do the import it gives an error.
This is a bug. If it can't accept the column header then it shouldn't allow it to be mapped but more appropriately if it is a CSV import than it should accept standard ascii characters in column names just like it should in column data.

Hi, @cgetsadmin! Thank you for taking the time for giving us your feedback! At this time, the process of importing orders is working as designed, however I see your point where it is frustrating to go through a process only to be turned around to double up on work.
As such, the product team will review your idea and you’ll hear from us once we’ve made a decision.
Today, symbols and punctuations are generally not allowed as column headers and you must remove them in order to import orders via CSV. One thing you can do right now is to see if other users are interested in a ShipStation partnership with your order source here in the forum. That way you can circumvent the CSV import process in its entirety!
