ASP.NET Excel Framework
Import and export Microsoft Excel workbooks in high-fidelity, with a compiled assembly that reads and writes in the widely-interoperable XLS/XLSX file format. Your web application can run completely independently of Excel.DOWNLOAD ASP.NET Samples
Flip simple shape types horizontally or vertically, or change their outline or fill colors.
Excel with no Excel
Bring the portability of workbook files in Microsoft Excel 2010 compatible file formats (.XLS, .XLSX and ExcelML) that run independently of Microsoft Excel, so it does not need to be installed on the client or server.
This is neither a wrapper around native OLE file system libraries, nor a callback to server-side code.
Read or Write Excelml
Use the compiled assembly to read in existing Excel files from the user’s local system. Or generate new Excel files and save them in the widely-compatible .XLS, .XLSX and ExcelML formats.
Workbook Object Model
Represents the gamut of Excel objects available including Workbooks, Worksheets, Cells, Formulas, and more. Note that only Bitmap backgrounds are supported at this time.
