The following macro (suitably modified) will do it:
Sub AddHyperlinks()
' add a hyperlink to A1 on sheet Index to B2 on each worksheet
Dim WS As Worksheet
Const HyperAdd = "B2" ' the cell in which you want the hyperlink
For Each WS In ActiveWorkbook.Worksheets
If WS.Name <> "Index" Then
With WS.Range(HyperAdd)
If .Hyperlinks.Count = 1 Then .Hyperlinks(1).Delete
WS.Hyperlinks.Add WS.Range(HyperAdd), "", "Index!A1", , "Index"
End With
End If
Next
End Sub
