- Create a new file with a text editor (e.g. Notepad, TextEdit) or a spreadsheet application (e.g. Excel, Numbers).
- Do one of the following:
- If you are using a text editor, enter your specific data set as a list of one item per line.
- If you are using a spreadsheet application, enter your specific data set as a list of one item in each cell row, starting in cell A1.
- Save the file with a .csv file extension or export the file to a CSV format. If you are saving from a text editor, you might need to select All Files from the Save as Type drop-down list and type the .csv ending in the file name.
Try typing quotation marks " " around your < file name >.csv if you encounter issues saving your CSV file.
