Why does windows call a workbook a worksheet?

Mark

I am just guessing this! Although you are saving a 'worksheet' your are saving it as a 'Excel Workbook Style' Format.  The reason I have come to this conclusion is because if you save an Excel Worksheet' you do save it as an 'Excel Workbook' Format>Click on File>Options>Save> and you will see what I mean.

A workbook is a set of worksheets, if you open a worksheet from explorer or recent in Excel the workbook will open with the specific worksheet highlighted/active

Hi, thanks for answering, this is what I mean.

It says workbook in the file type and worksheet in the folder listing.

Hi Mark,

Hi,  when I save a file in excel (2013 on windows 10) the save as file type is 'Excel Workbook (*.xlsx)', however in windows folder listings the file type is 'Microsoft Excel Worksheet'. Why is this? surely it is a workbook that contains one or more worksheets? Is the folder listing wrong?

I suspect that Window's use of the description Worksheet harks back to the early days of spreadsheets (e.g.Multiplan and Lotus123) when these comprised a single sheet; the term Workbook was adopted with the introduction of of multiple sheets.

Are you using 'Save As' within excel?
