[Qgis-user] ctrl-c selection issue

[Mike Flannigan]

Hi,

I would recommend not using Excel to modify CSV files.  That
program has a reputation for changing numbers to dates and
performing other modifications to the file contents that may
not be wanted.

Personally I use the Text::CSV module in Perl, but there are
many other methods to modify a CSV file without the changes that
Excel imposes on you.
