I'm trying to format 2 columns of data into numeric format using the
code shown below, but its not working. There are blank cells in the
data; otherwise, I would do a select-down-format. The columns are J
and K. Thanks.

Dim LastRow As Long
LastRow = Cells(Rows.Count, "G").End(xlUp).Row
Range("J2" & LastRow).NumberFormat = "#,##0.00_);[Red](#,##0.00)"
Range("K2" & LastRow).NumberFormat = "#,##0.00_);[Red](#,##0.00)"

Sample data:
