Export all leads in a campaign

Export all leads in a campaign

I have 7000 leads in my database. We use an external software for emails. What I need is to export all my leads in the campaign. 

The only export option I can find is the general one. This put's the whole lead table to an excel file. That would work as a second option but that export is limited to 3000 items? 

1. Export all leads in my Campaign
2. If not, how can I export all 7000 items

Kind regards,
