Sheets("Sheet1") vs. Worksheets("Sheet1")
The Sheets collection includes both worksheets (cells) and chart sheets.
The Worksheets collection does not include chart sheets.
Sheets.Count >= Worksheets.Count
If you don't use charts, Sheets is shorter to type.
Range("a1") vs. Cells(1,1)
Range is good for when I don't remember wheter M is 13th letter or the 14th.
For looping, Cells is better (IMO). I find it easier to read
than
The two argument Range is very useful
Range(Range("a1"),Range("b2")) = Range("a1:b2")
Does that help?
