This is a quick video on how to save your finished data files in Excel to CSVs.
If you've yet to create your data files, go back and review these articles:
Navigate to the Excel tab you wish to turn into a CSV file. Click File and choose the Save As... option.
By default, the file format selected will be an Excel format. Click on the file format drop-down menu and select Comma Separated Values (.csv).
Make sure the title of your file reflects the content of the CSV. For example, have the word "Teachers" in the name of the Teacher CSV file. Click Save.
Note: You may get a warning that you will not be able to take advantage of some of the features of Excel. This is to be expected when creating a CSV from an existing Excel sheet. Click Save Active Sheet and then Continue.
Repeat Steps 1-3 for all sheets of your Excel file to create the remaining CSV files.
