Sharing Excel Files

Steps for sharing a Google Spreadsheet with specific individuals

1. Login to Google Spreadsheets with your Google account.
2. Create or upload the spreadsheet you wish to share.
3. Click on the “Show sharing options” link in the top right corner of the screen.
4. Add the email addresses of the people you want to invite to either view or edit your spreadsheet.
5. Click on the “invite people” button to bring up the Invitation screen. This screen contains an email message to the invitees. The message includes a link to the spreadsheet and an area for you to include a personal message.

Note: If you send invitations to non-gmail addresses (Google’s own email service) those individuals will have to create a Google account using that email address before they can view the spreadsheet. Even if they have their own Google account, they will not be able to use it to log in and view the spreadsheet. They must use the email addressed specified in the invitation.
