Go to https://drive.google.com/ in your computer's web browser. This will open your Google Drive page if you're logged into your Google Account. If you aren't logged into your Google Account, enter your email address and password when prompted before you proceed. It's in the upper-left side of the page. A drop-down menu will appear. This is in the drop-down menu. Clicking it opens a File Explorer (Windows) or Finder (Mac) window. Go to the download location of the "contacts" vCard file you exported, then click the vCard file once to select it. It's in the bottom-right corner of the window. The vCard file will be uploaded to Google Drive. Again, on a Mac, you may click Choose here.
