Make a macro run on rows/columns only if data is present?

How can I mave a macro run on fields where there is data present and
ignore empty rows or columns. I have macros that I use regularly, but
the number of rows of data in these spreadsheets varies each time.
Thanks in advance for any help you can provide!

You can build If .... Then....Else....End IF statements that check the cells
Dim cel as range

If len(cel)>0 then
' cell is not blank
' do something
End if

If cel = 0 then
' cell has no value except 0
' don't do anything
Else
'do something
End if

And you can put one or more of those statements into a For .. Next loop

For each cel in Range("A1:Z55") ''' change the range to suit your needs
' your code
Next

There are other ways of restricting the ranges that make it even easier.
But we need to know more about what you really have and what you really are
looking at...

What I have is a macro that inserts a column and fills the cells in
that column with certain text. I only need the cells filled down to
the row where the existing data in the adjacent column ends.

This snippet looks at column A and finds the last used cell (even if there
are some empty cells in the column) You should be able to make this code
fit your needs.

Dim lrw As Integer

lrw= Cells(Rows.COUNT, "A").End(xlUp).Row

This one counts the number of used cells in column A (good if there are no
empty cells)
lrw = WorksheetFunction.Counta(Columns(1))

in either case the fill range could be written as
Set FRange = Sheets("Sheet1").Range("B1:B" & lrw)
