Selectable field delimiter for CSV files

Using comma as the field delimiter in CSV files does not work well when importing a file in Excel in Sweden. In the Swedish locale a comma is a decimal delimiter and semicolon is used as field delimiter. In Excel it is possible to select delimiter used but it does not work flawless anyway. Line breaks still causes problems.

This would allow a simple form of integration between tools for us without any need for manual editing of files in between.
