Hi, you could try going in your spreadsheet and delete columns/rows that are seemingly empty (delete a lot a of them), then try again. Sometimes in your spreadsheet you enter values then you delete them. This leaves the cells "active" and when you save the csv file, it writes some commas with nothing between them to account for those "active" cells. If you delete the rows/columns with possible active cells (which you can't know because they are empty, hence the need to delete a lot of them) you remove them from the data and the csv file doesn't have to account for those empty cells.
I hope this helps for future files! Cheers JM
