Unfortunately, Excel does not have a built-in option to pin specific tabs. However, you can create a VBA macro to achieve this. Here's the eg of how to implement it-
Private Sub Workbook_SheetActivate(ByVal Sh As Object)
Dim ws As Worksheet
Dim startSheet As Worksheet
'Set the reference to the "Start" worksheet
Set startSheet = ThisWorkbook.Worksheets("Start")
'Loop through each worksheet tab
For Each ws In ThisWorkbook.Worksheets
If ws.Name = "Start" Then
'Move the "Start" worksheet to the left-most position
ws.Move Before:=ThisWorkbook.Sheets(1)
Exit For
End If
Next ws
End Sub
Apart from this, there might be third-party Excel add-ins that offer more advanced tab management features, including the ability to pin tabs. Best Regards.
