If you choose to work in Excel, no problem! You can easily export a CSV file from the Excel template.
You can convert an Excel worksheet to a CSV file by using the Save As command. Click the File tab, and then click Save As. In the Save as type box, choose the text file format for the worksheet. For example, click CSV (Comma delimited).
