Sorry I do not mean to waste your time before sending a question to support, so I should have mentioned that of course I read the FAQ prior to sending a Support Question.
I have attached a screen shot, when I follow the Instructions
For the Single quote mark ( ‘ ) before and after ‘Columns’ I tried both a double and a single. Since A leading single quote (apostrophe) is a “code” character used to designate the cell content as Text, It isn’t recognized in excel as a literal character, therefore I put a two inputs of (‘) so that one may appear in the cell. This didn’t solve the issue. Then I attempted the double quote mark. Also negative.
Do you have a instructional trouble shoot video or screen shot? I have to mention again that I have no errors uploading the CSV files, it just goes into uncategorized.
