Exporting into Excel

I will like to know how to export into excel in desktop version as the exported files are not in excel format. What should I do? Thank you.

For Windows OS - Open excel,
Open Windows Explorer and navigate to where the file is
Click on the icon to reduce down the WinExp window size - not the minimise icon
Drag the file and drop onto excel sheet and a dialog box will open
Check that the “tab” selection is ticked then click Ok
