export large target group to file

Good afternoon everyone

I'm currently trying to export a large target group to file in order to do an excel cross chek with another data source.

My necesity would be to do it directly from a table in GUI, without using follow up operations on the target group (as the entire target group does not get exported) or without an export channel from the campaign (as some parteners will have the message "cannot be contacted" and thus again will not be exported properly ).

Any input on how I could manage some high amonunts of data (>500 000 bp) directly from target group tables would be appreciated and rewarded.

Best regards
