Example 1

In this file there are separate prefixes in one line.

Only one prefix can be on a separate line.

Files in this format can't be imported.

Example 2

Values in the header are separated by ';' and all the following values in other lines are separated by ','.

This is not acceptable. All values in all files should be separated by either ';' or by ',' - but having both of these separators is unacceptable.

Files in such a format can't be imported.

The prefixes have '00' in front of them. No international prefix is allowed in front of a prefix.

Files in such a format can't be imported.
