I’m using Micorsoft 2007 and trying to open a file with a .PRN extension. This is a comma-delimited file and created several years ago from our legacy system. In the past, I would open the files using the Wizard and I would open it as a comma-delimited file in Excel. The file today only opens in Wordpad of Notepad. I must have it open in Microsoft EXCEL 2007. Any ideas?
