Creating an empty sheet

In order to create a new empty sheet, create a new workbook by clicking the "Add a workbook" button.

After that set a name to the new workbook and click the "Add a sheet" button.

Once you click it, you will see a dropdown to create a blank sheet or to import data. Click "Blank sheet".

This will automatically create a new empty sheet with a few empty rows and default columns. You are free to start from scratch and input data as you go!
