To e-mail a copy of a workbook you have open in Excel 2013 to a client or co-worker, choose File→Share→ Email (Alt+FDE). When you do this, a Send Using E-Mail panel appears with the following five options:
Send as Attachment to create a new e-mail message using your default e-mail program with a copy of the workbook file as its attachment file.
Send a Link to create a new e-mail message using your default e-mail program that contains a hyperlink to the workbook file. (This option is available only when the workbook file is saved on your company’s or ISP’s web server.)
Send as PDF to convert the Excel workbook to the Adobe PDF (Portable Document File) format and make this new PDF the attachment file in a new e-mail message. (Your e-mail recipient must have a copy of the Adobe Reader installed on his or her computer in order to open the attachment.)
Send as XPS to convert the Excel workbook to a Microsoft XPS (XML Paper Specification) file and make this new XPS file the attachment in a new e-mail message. (Your e-mail recipient must have an XPS Reader installed on his or her computer in order to open the attachment; this reader is installed automatically on computers running Windows 7 or Windows Vista.)
Send as Internet Fax to send the workbook as a fax through an online fax service provider. You will need an account with a service provider as well as the Windows Fax and Scan Windows feature installed.
After selecting the e-mail option you want to use, Windows opens a new e-mail message in your e-mail program with a link to the workbook file or the file attached to it. To send the link or file, fill in the recipient’s e-mail address in the To text box and comments you want to make about the spreadsheet in the body of the message before you click the Send button.
