Hi @rwldrn 

If we add always the separator '|' if we dont have either $type nor $carrier, we will end up with: | <number>

In other parts of the code we made the separator part of the value if exists, can we do something similar.

Here is an example:

(nice tool btw)

Also last comment here, are we using finally '|' as a separator or '\''

Thanks!
