PPT is the file format used by Microsoft PowerPoint Presentation 97 - 2003, while PPTX is created by PowerPoint Presentation 2007, 2010. PPTX file format enjoys the advantages of smaller size, higher security, and higher integration with other file formats. But the Microsoft Office version under 2007 cannot open PPTX PowerPoint presentation directly. This article will show you how to convert PPT file format to PPTX in C# with only three lines of code.
Make sure Spire.Presentation for .NET has been installed correctly and then add Spire.Presentation.dll as reference in the downloaded Bin folder though the below path: "..\Spire.Presentation\Bin\NET4.0\ Spire. Presentation.dll". Here comes to the details of how to output PPT to PPTX:
Step 1: Create a presentation document.
Presentation presentation = new Presentation();
Step 2: Load the PPT file from disk.
presentation.LoadFromFile(@"..\..\..\..\..\..\Data\sample4.ppt");
Step 3: Save the PPT document to PPTX file format.
presentation.SaveToFile("ToPPTX.pptx", FileFormat.Pptx2010);
Step4: Launch and view the resulted PPTX file.
System.Diagnostics.Process.Start("ToPPTX.pptx");
Full codes:
namespace Spire.Presentation.Demo
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void btnRun_Click(object sender, EventArgs e)
{
//create PPT document
Presentation presentation = new Presentation();
//load the PPT file from disk
presentation.LoadFromFile(@"..\..\..\..\..\..\Data\sample4.ppt");
//save the PPT document to PPTX file format
presentation.SaveToFile("ToPPTX.pptx", FileFormat.Pptx2010);

- Create a Symbol Bulleted List in PowerPoint
- Create an Image Bulleted List in PowerPoint
Install Spire.Presentation for .NET
To begin with, you need to add the DLL files included in the Spire.Presentation for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.
PM> Install-Package Spire.Presentation
Create a Numbered List in PowerPoint in C# and VB.NET
A numbered list in PowerPoint is a list of items where each item is preceded by a number or a sequence of numbers. It follows a sequential order, typically starting from 1 and progressing incrementally. Numbered lists are commonly used to present steps, instructions, rankings, or any information that requires a specific order.
To create a numbered list in a PowerPoint presentation using Spire.Presentation for .NET, you can follow these steps:
- Create a Presentation object.
- Get the first slide using Presentation.Slides[0] property.
- Append a shape to the slide using ISlide.Shapes.AppendShape() method and set the shape style.
- Specify the items of the list inside a String array.
- Create paragraphs based on the list items, and set the bullet type of these paragraphs to Numbered using ParagraphProperties.BulletType property.
- Set the numbered bullet style of these paragraphs using ParagraphProperties.BulletStyle property.
- Add these paragraphs to the shape using IAutoShape.TextFrame.Paragraphs.Append() method.
- Save the document to a PowerPoint file using Presentation.SaveToFile() method.
- C#
- VB.NET
using Spire.Presentation;
using Spire.Presentation.Drawing;
using System.Drawing;
namespace CreateNumberedList
{
internal class Program
{
static void Main(string[] args)
{
//Create a Presentation object
Presentation presentation = new Presentation();
//Get the first slide
ISlide slide = presentation.Slides[0];
//Add a shape to the slide and set the shape style
IAutoShape shape = slide.Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 50, 300, 200));
shape.Fill.FillType = FillFormatType.None;
shape.Line.FillType= FillFormatType.None;
//Add text to the default paragraph
TextParagraph paragraph = shape.TextFrame.Paragraphs[0];
paragraph.Text = "Required Web Development Skills:";
paragraph.Alignment = TextAlignmentType.Left;
paragraph.TextRanges[0].Fill.FillType = FillFormatType.Solid;
paragraph.TextRanges[0].Fill.SolidColor.Color = Color.Black;
//Specify the list items
string[] listItems = new string[] {
" Command-line Unix",
" Vim",
" HTML",
" CSS",
" Python",
" JavaScript",
" SQL"
};
//Create a numbered list
foreach (string item in listItems)
{
TextParagraph textParagraph = new TextParagraph();
textParagraph.Text = item;
textParagraph.Alignment = TextAlignmentType.Left;
textParagraph.TextRanges[0].Fill.FillType = FillFormatType.Solid;
textParagraph.TextRanges[0].Fill.SolidColor.Color = Color.Black;
textParagraph.BulletType = TextBulletType.Numbered;
textParagraph.BulletStyle = NumberedBulletStyle.BulletArabicPeriod;
shape.TextFrame.Paragraphs.Append(textParagraph);
}
//Save the result document
presentation.SaveToFile("NumberedList.pptx", FileFormat.Pptx2013);
}
}
}
Create a Symbol Bulleted List in PowerPoint in C# and VB.NET
A symbol bulleted list in PowerPoint uses symbols instead of numbers to visually represent each item. Symbol bulleted lists are useful for presenting non-sequential information or a collection of points without a specific order.
To create a symbol bulleted list in a PowerPoint presentation using Spire.Presentation for .NET, you can follow these steps:
- Create a Presentation object.
- Get the first slide using Presentation.Slides[0] property.
- Append a shape to the slide using ISlide.Shapes.AppendShape() method and set the shape style.
- Specify the items of the list inside a String array.
- Create paragraphs based on the list items, and set the bullet type of these paragraphs to Symbol using ParagraphProperties.BulletType property.
- Add these paragraphs to the shape using IAutoShape.TextFrame.Paragraphs.Append() method.
- Save the document to a PowerPoint file using Presentation.SaveToFile() method.
- C#
- VB.NET
using Spire.Presentation;
using Spire.Presentation.Drawing;
using System.Drawing;
namespace CreateSymbolBulletedList
{
internal class Program
{
static void Main(string[] args)
{
//Create a Presentation object
Presentation presentation = new Presentation();
//Get the first slide
ISlide slide = presentation.Slides[0];
//Add a shape to the slide and set the shape style
IAutoShape shape = slide.Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 50, 350, 200));
shape.Fill.FillType = FillFormatType.None;
shape.Line.FillType = FillFormatType.None;
//Add text to the default paragraph
TextParagraph paragraph = shape.TextFrame.Paragraphs[0];
paragraph.Text = "Computer Science Subjects:";
paragraph.Alignment = TextAlignmentType.Left;
paragraph.TextRanges[0].Fill.FillType = FillFormatType.Solid;
paragraph.TextRanges[0].Fill.SolidColor.Color = Color.Black;
//Specify the list items
string[] listItems = new string[] {
" Data Structure",
" Algorithm",
" Computer Networks",
" Operating System",
" Theory of Computations",
" C Programming",
" Computer Organization and Architecture"
};
//Create a symbol bulleted list
foreach (string item in listItems)
{
TextParagraph textParagraph = new TextParagraph();
textParagraph.Text = item;
textParagraph.Alignment = TextAlignmentType.Left;
textParagraph.TextRanges[0].Fill.FillType = FillFormatType.Solid;
textParagraph.TextRanges[0].Fill.SolidColor.Color = Color.Black;
textParagraph.BulletType = TextBulletType.Symbol;
shape.TextFrame.Paragraphs.Append(textParagraph);
}
//Save the result document
presentation.SaveToFile("SymbolBulletedList.pptx", FileFormat.Pptx2013);
}
}
}
Create an Image Bulleted List in PowerPoint in C# and VB.NET
An image bulleted list in PowerPoint replaces the traditional bullet points with small images or icons. Instead of using numbers or symbols, each item is represented by an image that adds a visual element to the list. Image bulleted lists are commonly used when you want to incorporate visual cues or represent items with relevant icons or graphics.
To create an image bulleted list in a PowerPoint presentation using Spire.Presentation for .NET, you can follow these steps:
- Create a Presentation object.
- Get the first slide using Presentation.Slides[0] property.
- Append a shape to the slide using ISlide.Shapes.AppendShape() method and set the shape style.
- Specify the items of the list inside a String array.
- Create paragraphs based on the list items, and set the bullet type of these paragraphs to Picture using ParagraphProperties.BulletType property.
- Set the image that will be used as bullets using ParagraphProperties.BulletPicture.EmbedImage property.
- Add these paragraphs to the shape using IAutoShape.TextFrame.Paragraphs.Append() method.
- Save the document to a PowerPoint file using Presentation.SaveToFile() method.
- C#
- VB.NET
using Spire.Presentation;
using Spire.Presentation.Drawing;
using System.Drawing;
namespace CreateImageBulletedList
{
internal class Program
{
static void Main(string[] args)
{
//Create a Presentation object
Presentation presentation = new Presentation();
//Get the first slide
ISlide slide = presentation.Slides[0];
//Add a shape to the slide and set the shape style
IAutoShape shape = slide.Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 50, 400, 180));
shape.Fill.FillType = FillFormatType.None;
shape.Line.FillType = FillFormatType.None;
//Add text to the default paragraph
TextParagraph paragraph = shape.TextFrame.Paragraphs[0];
paragraph.Text = "Project Task To-Do List:";
paragraph.Alignment = TextAlignmentType.Left;
paragraph.TextRanges[0].Fill.FillType = FillFormatType.Solid;
paragraph.TextRanges[0].Fill.SolidColor.Color = Color.Black;
//Specify the list items
string[] listItems = new string[] {
" Define projects and tasks you're working on",
" Assign people to tasks",
" Define the priority levels of your tasks",
" Keep track of the progress status of your tasks",
" Mark tasks as done when completed"
};
//Create an image bulleted list
foreach (string item in listItems)
{
TextParagraph textParagraph = new TextParagraph();
textParagraph.Text = item;
textParagraph.Alignment = TextAlignmentType.Left;
textParagraph.TextRanges[0].Fill.FillType = FillFormatType.Solid;
textParagraph.TextRanges[0].Fill.SolidColor.Color = Color.Black;
textParagraph.BulletType = TextBulletType.Picture;
IImageData image = presentation.Images.Append(Image.FromFile("icon.png"));
textParagraph.BulletPicture.EmbedImage = image;
shape.TextFrame.Paragraphs.Append(textParagraph);
}
//Save the result document
presentation.SaveToFile("ImageBulletedList.pptx", FileFormat.Pptx2013);
}
}
