Hi,
If you could provide a few sample lines I could take a look and see what are the options. It sounds like the delimiter is wrong (so it is tab not a comma, or 3 blank or ….). I am presuming you are wanting/trying to open the files in Excel and there is a data import tool that might help you although for 200+ files I wouldn't recommend it as after the first 3 you will get bored and frustrated!
If there is a way to identify each column correctly in the file then we can either do a search/replace in any old text editor or create a small application (I prefer C# but open to other languages) that parses the files into a valid CSV for you.
Kind regards,
Chris
