  • What VB.NET APIs can I use to insert & add worksheet(s) into source Excel file?
  • What VB.NET demo codes are offered to insert & add worksheet(s) into Excel .xlsx file?
  • Why do I need to choose RasterEdge VB.NET Excel sheet inserting control?
Easy to Use APIs
The VB.NET APIs encoded in this Excel sheet insertion control add-on is advanced and easy to use. Here we present the two APIs that are used to add & insert Excel sheet using VB.NET programming code.
Private Sub InsertPage(page As BasePage, index As Integer) Implements XLSXDocument.InsertPage
End Sub
Private Sub AddPage(page As BasePage) Implements XLSXDocument.AddPage
End Sub
To help you better understand above VB.NET Excel sheet inserting APIs, we will here list some points that you may need to read before using these APIs.
  • XLSXDocument: this VB.NET Excel sheet adding control SDK treats each Excel file as an XLSXDocument object which contains all worksheets' information. This programming class is derived from REDocument.
  • XLSXPage: this class is defined by RasterEdge as a method to represent one Excel sheet. Therefore, in general, an XLSXDocument instance contains multiple XLSXPage objects. Note: for a better demonstration, we regard one Excel sheet as a page.
  • AddPage: this VB.NET Excel sheet adding & inserting control add-on offers two methods for users to add & insert worksheet. Using this AddPage method, VB.NET developers can just insert an Excel sheet at the end of source Excel file.
  • InsertPage: Similar to AddPage, this method can also insert a blank or an existed worksheet drawn from other document file into target Excel file. Different from AddPage, this InsertPage method allows VB.NET developers to insert the sheet at any specified location. That means you can decide where the Excel sheet will be inserted.
Sample VB.NET Code
From this part, you will find detailed VB.NET codes to insert & add Excel worksheet(s) into source Excel file via AddPage or InsertPage method.

How to Insert Excel Sheet

Here we list two snippets of VB.NET sample codes, both of which use the Excel sheet inserting method InsertPage. Using the first demo VB.NET code, you can insert an empty worksheet into source Excel file and you can specify the location by defining the page index. For instance, you want to insert an empty sheet as Excel Sheet 4 and you can achieve that by inputting the page index value as 3.
''' </summary>
''' <param name="doc"></param>
''' <param name="idx"></param>
Public Sub CreateAndInsertEmptyPage(doc As XLSXDocument, idx As Integer)
Dim page As XLSXPage = DirectCast(doc.CreateEmptyPage(), XLSXPage)
doc.InsertPage(page, idx)
End Sub
Using this VB.NET sample code, developers can insert one Excel sheet that is extracted from another Excel document into target Excel file. If you want to know detailed VB.NET code on how to extract Excel sheet from .xlsx file, please read this VB.NET Excel worksheet extraction tutorial page.
''' </summary>
''' <param name="doc"></param>
''' <param name="page"></param>
''' <param name="idx"></param>
Public Sub InsertPageToXLSXDocument(doc As XLSXDocument, page As XLSXPage, idx As Integer)
doc.InsertPage(page, idx)
End Sub

How to Add Excel Sheet

The following VB.NET sample code is mainly used to add an Excel sheet drawn from other Excel file source to the end of target Excel document.
''' <summary>
''' Add sheet to the end of the Excel document.
''' </summary>
''' <param name="doc"></param>
''' <param name="page"></param>
Public Sub AddPageToDocument(doc As XLSXDocument, page As XLSXPage)
End Sub
