.csv file modification

Of course you can. What is different now than before? How did you used to modify the CSV files? And why does it not work for you now?

PT

Just highlight the file, right click->open with->choose program->select Excel-check 'Always use the selected program to open this kind of file

If I use Excel and make no modification it is working ok, but if I make any modification then it is telling me that I am using a file from a nother computter something like (Exel 97/2000 & 5.0/95).
So if I save the file, it is not reusable, my GPS is not accepting it any more.

What I did is use my note bloc (text file) and it is working ok. ???????

Sounds like different versions of Office which Excel is part of. Should be able to convert between versions using the pull down menu in Excel but I don't recall how its done. Maybe someone else is more savy than I.

All Excel is telling you is that the file is not being saved in its native format (.xls) and that you will lose any formatting.
You can just disregard Excel's warning, since all you need is a .csv text file.

.csv is not Excel's native file format SO.........
You MUST do a "save as" and tell it to save as a .csv AND ignore the warnings about losing formatting or whatever.

save as the file with a .csv extension , not .xls!!

Thank's for all the info.
