I have a spreadsheet I download from a different department every day. Often there are 80-90 rows of data. All the rows have data in columns A & B, but sometimes they have more SPECIFIC data in columns C & D. So if there is data in C & D I copy & paste that into A / B (over the data there.) I have some basic macro knowledge, but I'm a little lost when it comes to "if C / D != blank then C / D copy and paste into A / B." Any help y'all can provide would be SUPER. Thanks in advance!
