Sort by absolute value

I need help with a macro that sorts a range of data based on the absolute value of a column.

For example, if column 3 contains the + or - number values, sort all of the rows based on the absolute value of column 3.

Unfortunately, I don't really have any idea on where to start so any help would be appreciated

Do you need a macro? Are you able to use a helper column? You can just put in a helper column =ABS() and sort by that.

That would be ideal. This would be part of a bigger macro
