Microsoft Office Web Components are a collection of Component Object Model (COM) controls for publishing spreadsheets, charts, and databases to the Web. They are also used to view these items when published, as well as data access pages.
If you have Microsoft FrontPage 2002, Microsoft Access 2002, and Microsoft Excel 2002 installed, Office Web Components allow you to publish interactive data as part of a Web page. Using Microsoft Internet Explorer version 4.01 or later, Office Web Components allow you to view a published control (Spreadsheet, chart, or database) on a Web page. With Internet Explorer version 5 or later, Office Web Components allow you to view data access pages.
By installing The Office Web Components tool, you can view published components and data access pages on the Web without having to install Office XP. Note: If you do not own an Office XP license, the Office Web Components are licensed to be used in Static, non-interactive, client-side, view-only mode. If you do own an Office XP license, the Office Web Components are licensed to be used in interactive mode.
