Request to format the data for customers when they upload a list. Currently, if customers upload a list where the numerical data is inserted into the template as a number instead of text it fails to upload the list.
If this can not be an automated fix - no where in the template or the list upload feature is there any indication that customers need to format numbers as text. Most users will naturally enter numerical data in the sheet as numbers, so it's essential to update the template or provide clear guidelines on how to format the data properly.
