Review documents in the Office Online viewer

You can review native files directly in the application using Microsoft Office Online, without having to download documents to your computer.

In the Office Online viewer, you can perform the following tasks:

Search for content

See formulas, resize columns, and display hidden worksheets, rows, and columns in a Microsoft Excel spreadsheet
