Question

I want to be able to dynamically select a range of cells (the heading row), where the row is 1 but the columns with be for 1 to last column, where “A” is the first Column and where “M” is the last column. I know how to find the last column, but I don’t know how to modified the below range to input the first and last column as “A” and “M”.

 Range("A1:M1").Select

Answer 1

If you want to select a variable range containing all headers cells:

Dim sht as WorkSheet
Set sht = This Workbook.Sheets("Data")

'Range(Cells(1,1),Cells(1,Columns.Count).End(xlToLeft)).Select '<<< NOT ROBUST

sht.Range(sht.Cells(1,1),sht.Cells(1,Columns.Count).End(xlToLeft)).Select

…as long as there’s no other content on that row.

EDIT: updated to stress that when using Range(Cells(...), Cells(...)) it’s good practice to qualify both Range and Cells with a worksheet reference.
