hide multiple sheets in excel vba code example

Example: Excel VBA hide sheets with names in array

Sheets(arr).Visible = False

'Note1: For this to work without an error, 'arr' needs to be a 1D array with a 
'       valid and actual sheet name in each element.

'Note2: An array cannot be used to make sheets visible if they are hidden.
'       This array technique only works to hide visible sheets.
