Office Web Components is a set of ActiveX® controls installed with Office XP. However, if you previously chose not to install this set, you can download it from Office XP Tool: Web Components, on Office Online .

With a spreadsheet, you can enter and perform calculations on data or create lists of information. When you enter data into the cells of the spreadsheet, you can create formulas that perform calculations on the data just as you would create formulas in Microsoft Excel.

The following example is a spreadsheet on a Web page designed to be used as a mortgage calculator. When the user changes the values in the bordered input cells in the browser, the spreadsheet calculates the mortgage payment.

The Spreadsheet component provides formulas, totals, and sorting and filtering functionality, just as you find in Excel worksheets. Users can take advantage of Excel worksheet functions as well.

In calculations, you can use data from spreadsheet cells or other controls on the page, as well as URLs using the document object model in Microsoft Internet Explorer. You can create Web pages with spreadsheets by either publishing a worksheet using Excel, or by inserting a Spreadsheet component using the data access page Design view in Microsoft Access or Microsoft FrontPage®.
