VBA Check if Sheet Exists

I have a solution for checking if an Excel worksheet exists or not. This can come in handy if you are creating a new sheet based on a dataset. You check for the new sheet and if the sheet exists you can alter the old sheet if the sheet does not exist then you can create a new sheet.

If Not Evaluate("ISREF('" & [A1] & "'!A1)") Then

Where Excel cell [A1] contains the name of the sheet you are checking for.

Now if this procedure was part of a loop you may wish to check all of the cells from say A1 to the last used row in column A. Then the following might be more relevant.
