Excel Reader .NET

Excel Reader .NET is a professional component that enables .NET developers to read Excel Spreadsheet files ( XLSX , XLS , CSV ) from .NET applications or website projects (C#, VB.NET). The Excel spreadsheet is represented as a tree structure. Root of the tree is an ExcelWorkbook object that has different Worksheets and so on.

Standalone .NET Component

Excel Reader .NET component requires only .NET Framework and is many times faster than Excel automation objects. The code of Excel Reader .NET component is fully managed and works under .NET Framework started from 2.0 version. Developers can create C# / VB.NET applications or deploy website on servers with medium-trust level without needing to rely on Microsoft Excel. Look at the following table.

Why Excel Reader .NET better than automation:

Excel Reader .NET MS Excel Automation
Excel Reader .NET doesn't require installed Microsoft Excel. Requires a license for Microsoft Excel on every client machine.
Excel Reader is a standalone .NET component taking 0.5 MB. Excel is loaded in the background, loading a large number of components and taking a time.
Excel Reader .NET is designed for processing large number of Excel files. Microsoft Excel was designed as UI application and because of that API is very slow.
Files generated with Excel Reader .NET are compatible with Excel 97, Excel 2000, Excel XP, Excel 2003, Excel 2007, Excel 2010 and OpenOffice. Requires that all client machines have the same version of Microsoft Excel installed.
Excel Reader is a pure .NET component. Microsoft Excel API is a COM library with bad integration with .NET Framework.

Clean Excel Object Tree

Easy to use API

Excel Reader .NET is designed and developed to provide with convenient object model and easy in use API.
Look at code(C#) below:

  1. // Open Excel spreadsheet
  2. ExcelWorkbook Wbook = ExceWorkbook.ReadXLS

  3. // Selection of worksheet
  4. ExcelWorksheet Wsheet = Wbook.Worksheets["Sheet1"];

  5. // Selection of Cell A5
  6. ExcelCell A5 =

  7. // Getting Cell attributes
  8. string s =
  9. Color color =

The plain code will help a developer to manage any complex Excel spreadsheet.
