Exports often include dozens of columns, but you may need only three. A smaller file is easier to read, faster to import and safer to share, because private fields are left out.

Privacy first
Before sending a file to a vendor or a friend, ask what they really need. Removing everything else is a simple way to share less personal data, which is both safer and more respectful of your customers.
After extracting
The kept columns stay in their original order. If you need a different order, open the file in a spreadsheet and drag the columns.
