Hi, if you're referring to NEWT Pro, then you can limit data you export from a tab. To limit rows, select the rows you want to export and visit File, Export and there should be a selected rows feature. To limit columns, go to Scan Properties and disable the data you don't want to see. However you can only do the latter with the Primary, System, Network and Windows tabs. All other tabs can only be limited by rows. I hope that helps!
