C#/VB.NET: Group or Ungroup Shapes in Excel
Sometimes, you may need to perform specific operations on multiple shapes in Excel, such as adding styles, resizing, or moving them around. Grouping shapes can help you accomplish this task more easily and efficiently. Once shapes are grouped, they are treated as a single entity and can be manipulated at the same time. In this article, you will learn how to programmatically group or ungroup shapes in Excel in C# and VB.NET using Spire.XLS for .NET.
Install Spire.XLS for .NET
To begin with, you need to add the DLL files included in the Spire.XLS for .NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.

Group Shapes in Excel using C# and VB.NET
To group certain shapes in an Excel worksheet, you need to use the Worksheet.GroupShapeCollection property to return a GroupShapeCollection object, and then call the GroupShapeCollection.Group() method. The following are the detailed steps:
- Initialize an instance of Workbook class.
- Get the first worksheet by its index through Workbook.Worksheets[int] property.
- Add several shapes to specific rows and columns in the worksheet using Worksheet.PrstGeomShapes.AddPrstGeomShape(int, int, int, int, PrstGeomShapeType) method.
- Get the group shape collection of the worksheet through Worksheet.GroupShapeCollection property.
- Group the shapes using GroupShapeCollection.Group(IShape[]) method.
- Save the result document using Workbook.SaveToFile(string) method.
- C#
- VB.NET
using Spire.Xls;
using Spire.Xls.Core;
using Spire.Xls.Core.MergeSpreadsheet.Collections;
using System.Drawing;
namespace GroupShapes
{
class Program
{
static void Main(string[] args)
{
//Create a Workbook instance
Workbook workbook = new Workbook();
//Get the first worksheet
Worksheet worksheet = workbook.Worksheets[0];
//Add four shapes
IPrstGeomShape shape1 = worksheet.PrstGeomShapes.AddPrstGeomShape(3, 3, 65, 50, PrstGeomShapeType.RoundRect);
shape1.Fill.FillType = ShapeFillType.SolidColor;
shape1.Fill.ForeColor = Color.Yellow;
shape1.Line.Weight = 0.1;
IPrstGeomShape shape2 = worksheet.PrstGeomShapes.AddPrstGeomShape(7, 3, 65, 50, PrstGeomShapeType.Ribbon);
shape2.Fill.FillType = ShapeFillType.SolidColor;
shape2.Fill.ForeColor = Color.Purple;
shape2.Line.Weight = 0.1;
IPrstGeomShape shape3 = worksheet.PrstGeomShapes.AddPrstGeomShape(3, 5, 65, 50, PrstGeomShapeType.Cloud);
shape3.Fill.FillType = ShapeFillType.SolidColor;
shape3.Fill.ForeColor = Color.LightGreen;
shape3.Line.Weight = 0.1;
IPrstGeomShape shape4 = worksheet.PrstGeomShapes.AddPrstGeomShape(7, 5, 65, 50, PrstGeomShapeType.Ellipse);
shape4.Fill.FillType = ShapeFillType.SolidColor;
shape4.Fill.ForeColor = Color.LightSkyBlue;
shape4.Line.Weight = 0.1;
//Group the shapes
GroupShapeCollection groupShapeCollection = worksheet.GroupShapeCollection;
groupShapeCollection.Group(new IShape[] { shape1, shape2, shape3, shape4});
//Save the result file
workbook.SaveToFile("GroupShapes.xlsx", ExcelVersion.Version2013);
}
}
}
Ungroup Shapes in Excel using C# and VB.NET
To ungroup the grouped shapes in an Excel worksheet, you can use the GroupShapeCollection. UnGroupAll() method. After the shapes are ungrouped, you can manipulate them individually. The following are the detailed steps:
- Initialize an instance of Workbook class.
- Load an Excel file using Workbook.LoadFromFile() method.
- Get a specific worksheet by its index through Workbook.Worksheets[int] property.
- Get the group shape collection of the worksheet through Worksheet.GroupShapeCollection property.
- Ungroup all the grouped shapes using GroupShapeCollection.UnGroupAll() method.
- Save the result document using Workbook.SaveToFile() method.
- C#
- VB.NET
using Spire.Xls;
using Spire.Xls.Core.MergeSpreadsheet.Collections;
namespace UngroupShapes
{
class Program
{
static void Main(string[] args)
{
//Create a Workbook instance
Workbook workbook = new Workbook();
workbook.LoadFromFile("GroupShapes.xlsx");
//Get the first worksheet
Worksheet worksheet = workbook.Worksheets[0];
//Ungroup the grouped shapes in the worksheet
GroupShapeCollection groupShapeCollection = worksheet.GroupShapeCollection;
groupShapeCollection.UnGroupAll();
//Save the result file
workbook.SaveToFile("UnGroupShapes.xlsx", ExcelVersion.Version2013);

// Dispose resources
workbook.Dispose();
}
}
}
Remove Shapes from Excel in C#
The Worksheet.PrstGeomShapes property returns a collection of shapes within a worksheet. To remove a specific shape from the collection, use the PrstGeomShapeCollection[index].Remove() method, where the index specifies the shape's position. To delete all shapes, you can iterate through the collection and remove each shape individually.
The steps to remove a shape in an Excel worksheet are as follows:
- Create a Workbook object.
- Load an Excel file using the Workbook.LoadFromFile() method.
- Get a specific worksheet through the Workbook.Worksheets[index] property.
- Get the shape collection through the Worksheet.PrstGeomShapes property.
- Remove a specific shape using the PrstGeomShapeCollection[index].Remove() method.
- Save the workbook to a different Excel file.
The following code demonstrates how to load an existing Excel file, remove specific shapes or all shapes from a worksheet.
- C#
using Spire.Xls;
using Spire.Xls.Core.Spreadsheet.Collections;
namespace RemoveShapesFromExcel
{
class Program
{
static void Main(string[] args)
{
// Create a Workbook object
Workbook workbook = new Workbook();
// Load an Excel file
workbook.LoadFromFile("C:\\Users\\Administrator\\Desktop\\Shapes.xlsx");
// Get a specific worksheet
Worksheet sheet = workbook.Worksheets[0];
// Get the shape collection from the worksheet
PrstGeomShapeCollection shapes = sheet.PrstGeomShapes;
// Remove a specific shape
shapes[1].Remove();
/*
// Remove all shapes
for (int i = shapes.Count - 1; i >= 0; i--)
{
shapes[i].Remove();
}
*/
// Save the workbook to an Excel file

Adding Picture to Excel Textbox in C#, VB.NET
Textbox in Excel is a special kind of graphic object, which allows users to add some text in it. Moreover, textbox can be filled with solid color, gradient, pattern or a picture so that it looks more attractive. This article presents how to add a picture fill to Excel textbox and adjust the position of the picture as well.
Code Snippets:
Step 1: Create a new instance of Workbook class and get the first worksheet.
Workbook workbook = new Workbook(); Worksheet sheet = workbook.Worksheets[0];
Step 2: Add a textbox shape into the worksheet.
ITextBoxShape shape = sheet.TextBoxes.AddTextBox(2, 2, 200, 300);
Step 3: Fill the textbox with a 160x160 pixels picture.
shape.Fill.CustomPicture(@"C:\Users\Administrator\Desktop\logo.png"); shape.Fill.FillType = ShapeFillType.Picture;
Step 4: Save the file.
workbook.SaveToFile("PicFill.xlsx", ExcelVersion.Version2013);
When we add a picture fill to a textbox using above code, the picture will stretch to fill the shape, like below screenshot.
If you want to prevent the image from stretching, you can adjust the size of the textbox or change the position of the picture, for example, place the image at the central position of the textbox. Following code snippet demonstrates how to center align the picture fill.
//If the height of textbox is larger than the height of original picture, set the picture into vertical center
if (textbox.Height > textbox.Fill.Picture.Height)
{
int difH = textbox.Height - textbox.Fill.Picture.Height;
(textbox.Fill as XlsShapeFill).PicStretch.Top = difH * 100 / (textbox.Height * 2);
(textbox.Fill as XlsShapeFill).PicStretch.Bottom = difH * 100 / (textbox.Height * 2);
}
//If the width of textbox is larger than the width of original picture, set the picture into horizontal center
if (textbox.Width > textbox.Fill.Picture.Width)
{
int difW = textbox.Width - textbox.Fill.Picture.Width;
(textbox.Fill as XlsShapeFill).PicStretch.Left = difW * 100 / (textbox.Width * 2);
(textbox.Fill as XlsShapeFill).PicStretch.Right = difW * 100 / (textbox.Width * 2);
}

How to Insert OLE Object in Excel in C#, VB.NET
OLE object is used to make content created in one program available in another program, for instance, we can insert Word as OLE object in Excel sheet.
As a robust component, Spire.XLS supports to insert Word and PowerPoint slide as linked object or embedded object into Excel. In this article, we make an example to explain how to insert Word as OLE object into Excel using Spire.XLS and Spire.Doc. Before coding, you need to download Spire.Office and reference related the Dlls in your VS project.
Code Snippet:
Step 1: Define a GetDocImage(string doxcFile) method to get olePicture. Actually, the olePicture is an image of data information in original Word document. The image generated from the specified page will be shown in Excel sheet after inserting OLE object into it.
private static Image GetDocImage(string docxFile)
{
Document document = new Document();
document.LoadFromFile(docxFile);
return document.SaveToImages(0, Spire.Doc.Documents.ImageType.Bitmap);
}
Step 2: Insert OLE object in Excel. After getting the worksheet from Excel file, we call GetDocImage(string doxcFile) method which is defined in the first step to get image source and then use the ws.OleObjects.Add(string FileName, Image image, OleLinkType linkType) method to insert the new OLE object to worksheet.
static void Main(string[] args)
{
//load Excel file
Workbook workbook = new Workbook();
workbook.LoadFromFile("d:\\sample.xlsx");
Worksheet ws = workbook.Worksheets[0];
//insert OLE object
string docx = "d:\\sample.docx";
Image image = GetDocImage(docx);
IOleObject oleObject = ws.OleObjects.Add(docx,image,OleLinkType.Embed);
oleObject.Location=ws.Range["B4"];
oleObject.ObjectType = OleObjectType.WordDocument;
//save the file
workbook.SaveToFile("result.xlsx",ExcelVersion.Version2010);
System.Diagnostics.Process.Start("result.xlsx");
}
Result:

Document document = new Document();
document.LoadFromFile(docxFile);
return document.SaveToImages(0, Spire.Doc.Documents.ImageType.Bitmap);
}
static void Main(string[] args)
{
//load Excel file
Workbook workbook = new Workbook();
workbook.LoadFromFile("d:\\sample.xlsx");
Worksheet ws = workbook.Worksheets[0];
//insert OLE object
string docx = "d:\\sample.docx";
Image image = GetDocImage(docx);
IOleObject oleObject = ws.OleObjects.Add(docx, image, OleLinkType.Embed);
oleObject.Location = ws.Range["B4"];
oleObject.ObjectType = OleObjectType.WordDocument;
//save the file
workbook.SaveToFile("result.xlsx", ExcelVersion.Version2010);
System.Diagnostics.Process.Start("result.xlsx");
