have you tried looking at help for hyperlinks?
=hyperlink("[book1]Sheet2!A1","click here")
Help says
You can create hyperlinks within a worksheet to jump from one cell to
another cell. For example, if the active worksheet is the sheet named June in
the workbook named Budget, the following formula creates a hyperlink to cell
E56. The link text itself is the value in cell E56.
=HYPERLINK("[Budget]June!E56", E56)
To jump to a different sheet in the same workbook, change the name of the
sheet in the link. In the previous example, to create a link to cell E56 on
the September sheet, change the word "June" to "September."
