Important

The Workbook class is defined in the DevExpress.Docs.v19.1.dll assembly. Add this assembly to your project to use the workbook functionality. You require a license to the DevExpress Office File API or DevExpress Universal Subscription to use this assembly in production code. Refer to the DevExpress Subscription page for pricing information.

To load an existing spreadsheet document into the Workbook object, use the Workbook.LoadDocument method.

• Load from File

  Create a new Workbook object and call the Workbook.LoadDocument method with the passed file path to load a workbook from the existing file. Specify the file format as the second parameter of the method using the DocumentFormat enumerator.

  C#

  // Add a reference to the DevExpress.Docs.dll assembly.
  using DevExpress.Spreadsheet;
  // ...
  
  Workbook workbook = new Workbook();
  
  // Load a workbook from the file.
  workbook.LoadDocument("Documents\\Document.xlsx", DocumentFormat.Xlsx);
  

  VB.NET

  ' Add a reference to the DevExpress.Docs.dll assembly. 
  Imports DevExpress.Spreadsheet
  ' ...
  
  Dim workbook As New Workbook()
  
  ' Load a workbook from the file.
  workbook.LoadDocument("Documents\Document.xlsx", DocumentFormat.Xlsx)
  

• Load from Stream

  Create the FileStream object with the specified file path to open the existing file, and call the Workbook.LoadDocument method with this stream object passed as a parameter. Specify the file format as the second parameter of the method using the DocumentFormat enumerator.

  C#

  
  // Add a reference to the DevExpress.Docs.dll assembly. 
  using DevExpress.Spreadsheet;
  using System.IO;
  // ...
  
  Workbook workbook = new Workbook();
  
  // Load a workbook from the stream.
  using (FileStream stream = new FileStream("Documents\\Document.xlsx", FileMode.Open)) {
      workbook.LoadDocument(stream, DocumentFormat.Xlsx);
  }
  

  VB.NET

  
  ' Add a reference to the DevExpress.Docs.dll assembly. 
  Imports DevExpress.Spreadsheet
  Imports System.IO
  ' ...
  
  Dim workbook As New Workbook()
  
  ' Load a workbook from the stream.
  Using stream As New FileStream("Documents\Document.xlsx", FileMode.Open)
      workbook.LoadDocument(stream, DocumentFormat.Xlsx)
  End Using
