# Excel for WPF and Silverlight Overview

## Content



Your Excel® data is just a simple command away from any of your .NET applications with **Excel for WPF and Silverlight (C1Excel)** – you don't even need to have Microsoft® Excel installed! Create or load XLS files for Excel 97 and later. **Excel for** **WPF and Silverlight** supports the new Office 2007 OpenXml format, which allows you to save smaller, compressed XLSX files.

The main component in **Excel for** **WPF and Silverlight** is the [C1XLBook](/componentone/api/wpf/online-excel/dotnet-framework-api/C1.WPF.Excel.4.6.2/C1.WPF.Excel.C1XLBook.html) object, which represents an Excel workbook containing one or more sheets. Use the **C1XLBook** to load existing Excel files or create new ones. Then add sheets, styles, hyperlinks, images, headers and footers, page breaks and more. When you are done, save the **C1XLBook** to a file or a Stream and you’re done. Anyone with a copy of Excel can access your data. It’s that easy!
