You can use following VBA code:
You can change the "mysheet" with you sheet  name. It will unhide  the sheet if
it is hideen.


Sub myload()
Dim mkc1 As Error
Dim sheet1 As String
sheet1 = "mysheet"

For Each ws In Worksheets
If ws.Name = sheet1 Then
edits = 1
End If


Next ws

if edits = 0 Then
Else
If Application.Worksheets(sheet1).Visible = True Then
Else
Application.Worksheets(sheet1).Visible = True
End If
End If
End Sub

I hope it works
