could you please tell me if you are on spreadsheet that has 3 worksheets, if
you are on 1 of the 3 worksheets and you want to go to an entirely new
spreadsheet, that is not part of that spreadsheet, can you do that and how?

or can you have worksheets under a worksheet in a spreadsheet?

Each workbook has three sheets as default. You can add or delete sheets. A
workbook can have up to 254 sheets.

You can hide a worksheet with sensitive information (Format. Sheet,Hide).

You can have more than one workbook open and can swith between them
(Windows, and select the name of the other workbook).

Formulas can also call informationLfrom other workbooks
