Is it possible to a macro go row by row and hide (or delete) and rows where column 1 is ""

The title says it all, can throw together a sample sheet if needed but its basically a sheet that I get from my acct program that always has excess lines, and the lines I need always have a code in column 1 so I want to set up a macro to go line by line and hide or delete lines with blanks in 1.

Something like a looping macro which I have a little exp with.

thoughts??

Thanks in advance.
