Export Google Sheet

I have a Google Sheet that includes custom App Script. I need to:

1. Download a copy of the sheet.
2. Zip up the sheet.
3. Send it to another user.

Is there a way to do this in Google Sheets? For privacy reasons, I can't just send a link to the Google Sheet. That's why I need to download the sheet, zip it up, and send it via email so the person can import it themselves.
