1.3 Saving Data: Worksheets and Projects
The used built-in Minitab extensions are .MTW for a worksheet and .MPJ for a project.
A file can only be retrieved in the same way it was previously saved. If it was stored as a worksheet, it can only be retrieved as such. The same is valid for projects.
Minitab interacts very well with Excel; an Excel spreadsheet can be imported using the option Open Worksheet (or copy and paste from Excel to Minitab).
