These files are extracted from a pocket logger software. It writes into a .pl2 file that has the data separated into three columns. However, the machine this software is on is old and I want to get rid of it. So I transferred over to a Windows 7 machine with Excel 2010. It should still work. But something happened now I get the following output into one column:

Date,Time,Ch1:
09/07/2007,12:26:51.000,10.684
09/07/2007,12:26:51.005,14.957

Before it was just separated into three columns.

Do I need to clarify?
