Office Web Apps allow users to view and edit Microsoft Office files directly from a web browser. Key features include:
1) Viewing documents, spreadsheets, presentations, and notebooks in their web browsers on any computer with an Internet connection.
2) Editing files directly in the browser or opening them in the full desktop Microsoft Office applications.
3) Viewing content in high fidelity so it appears the same as when created in Word, Excel, PowerPoint, and OneNote.
