I'm trying to import an Excel spreadsheet as a table, but I'm getting an error. I have a spreadsheet of products, and the SKU field has part numbers. The first 44 part number are numbers only. Beginning on the 45th part number, there are numbers and letters in the part numbers. The error field in the import error table, beginning with the first record with a letter in the part number, indicates "type conversion failure". I've changed the format of that column to text in Excel with no luck. I've imported other spreadsheets with numbers and letters in the part numbers with no problems. Any ideas?
