Improper or inflexible CSV format

[derSebastian]

By default CSV (Comma Separated Value) uses commas to delineate between columns or fields. This application it requires semi-colons. This can cause a problem when importing a CSV in two ways:

a) Will not properly import any data if comas are used (some software ONLY outputs the default comma)
b) Password contains a comma (it will skip and misalign all following information due to that 'offset' column.

Two solutions seems most appropriate:
Use commas as delineation character
and or
Let the user decide which character should be used as delineator? That might be the most flexible?
