Aspose.Excel delivers real Excel spreadsheets in a desktop or web server environment without Microsoft Excel installed on either server or user's computer.

Unlike similar products from other vendors, Aspose.Excel not only supports spreadsheet generation and other basic file formatting features, but also supports a number of advanced features. These advanced features make it much more convenient for developers to manipulate contents, format cells and protect files.

Besides supporting common features, such as: create native Excel files and read Excel files, Aspose.Excel also supports advanced features, such as: open and save to a stream; send output to a client browser; import and export data from a data table, a data view or an array; import image and chart; create image and chart through API; import formula from a designer spreadsheet; support add-in, VBA, and macro; support page setup through API.
