Table of contents > Import/open backup files using Microsoft Office
All backup data is compatible with Microsoft Office. For example, all Google Drive native files in Google Docs are automatically backed up to Microsoft Office file formats, which can be easily opened by Microsoft Office Word, Excel or PowerPoint.
Google Mail messages are backed up as EML (MIMI RFC 822) files, which can be directly opened by Microsoft Outlook Express as well as most other email programs. (However, the .eml file cannot be directly opened by Microsoft Outlook.).
Google Contacts data is downloaded as vCard (.vcf) files, which can be opened by Microsoft Outlook, Windows Contacts or any text editor.
Google Calendar data is backed up as standard iCalendar (.ics) files and can be opened by most calendar tools, such as Microsoft Outlook or Apple Calendar.
