PowerPoint to HTML conversion opens up opportunities for wider accessibility and enhanced interactivity. By transforming your presentations into HTML format, you can effortlessly distribute them across various platforms and devices. Whether you aim to share slides online or integrate them seamlessly within a web page, converting PowerPoint to HTML provides a flexible and versatile solution. In this article, we will explore how to convert PowerPoint files to HTML in Java using Spire.Presentation for Java.
- Convert a PowerPoint Presentation to HTML in Java
- Convert a Specific PowerPoint Slide to HTML in Java
Install Spire.Presentation for Java
First, you're required to add the Spire.Presentation.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.
<repositories>
<repository>
<id>com.e-iceblue</id>
<name>e-iceblue</name>
<url>https://repo.e-iceblue.com/nexus/content/groups/public/</url>

<artifactId>spire.presentation</artifactId>
<version>9.4.5</version>
</dependency>
</dependencies>
Convert a PowerPoint Presentation to HTML in Java
With Spire.Presentation for Java, you can convert PowerPoint files to HTML format in just three steps. The detailed steps are as follows:
- Initialize an instance of the Presentation class.
- Load a sample PowerPoint document using Presentation.loadFromFile() method.
- Save the PowerPoint presentation as HTML using Presentation.saveToFile() method.
- Java
import com.spire.presentation.FileFormat;
import com.spire.presentation.Presentation;
public class ToHtml {
public static void main(String[] args) throws Exception {
//Create a Presentation object
Presentation presentation = new Presentation();
//Load the sample document presentation.loadFromFile("C:\\Users\\Administrator\\Desktop\\sample.pptx");
//Save the document to HTML format presentation.saveToFile("C:\\Users\\Administrator\\Desktop\\ToHtml.html", FileFormat.HTML);
presentation.dispose();
}
}
Convert a Specific PowerPoint Slide to HTML in Java
Sometimes, it may be necessary to convert a single slide rather than the entire presentation to HTML. In such cases, Spire.Presentation for Java provides the ISlide.saveToFile() method for converting a PowerPoint slide to HTML format. The following are the detailed steps:
- Initialize an instance of the Presentation class.
- Load a sample PowerPoint document using Presentation.loadFromFile() method.
- Get the specific slide using Presentation.getSlides().get() method.
- Save the PowerPoint slide to HTML using ISlide.saveToFile() method.
- Java
import com.spire.presentation.FileFormat;
import com.spire.presentation.Presentation;
import com.spire.presentation.ISlide;
public class ConvertSpecificSlideToHtml { public static void main(String[] args) throws Exception {
// Create a Presentation object
Presentation presentation = new Presentation();
// Load the sample document presentation.loadFromFile("C:\\Users\\Administrator\\Desktop\\sample.pptx");
// Get the specific slide by index (e.g., index 0 for the second slide)
ISlide slide = presentation.getSlides().get(1);
// Save the specific slide to HTML format slide.saveToFile("C:\\Users\\Administrator\\Desktop\\SpecificSlideToHtml.html", FileFormat.HTML);
slide.dispose();
}
}

This article shows you how to create a chart in PowerPoint using the data from an existing Excel document. This solution relies on Spire.Office.jar. Please download the latest version from here and add it as a dependency in your project.
Below is a screenshot of the Excel document.
import com.spire.presentation.FileFormat;

import com.spire.xls.Workbook;
import com.spire.xls.Worksheet;
import java.awt.geom.Rectangle2D;
public class CreateChartFromExcelData {
public static void main(String[] args) throws Exception {
//Create a Presentation object
Presentation presentation = new Presentation();
presentation.getSlideSize().setType(SlideSizeType.SCREEN_16_X_9);
//Add a clustered column chart to slide
Rectangle2D rect = new Rectangle2D.Float(200, 100, 550, 320);
IChart chart = presentation.getSlides().get(0).getShapes().appendChart(ChartType.COLUMN_CLUSTERED,rect);
//Clear the default dummy data
chart.getChartData().clear(0,0,5,5 );
//Load an existing Excel file to Workbook object
Workbook wb = new Workbook();
wb.loadFromFile("C:\\Users\\Administrator\\Desktop\\data.xlsx");
//Get the first worksheet
Worksheet sheet = wb.getWorksheets().get(0);
//Import data from the sheet to chart table
for (int r = 0; r < sheet.getAllocatedRange().getRowCount(); r++)
{
for (int c = 0; c < sheet.getAllocatedRange().getColumnCount(); c++)
{
chart.getChartData().get(r,c).setValue(sheet.getCellRange(r+1, c+1).getValue2());
}
}
//Add chart title
chart.getChartTitle().getTextProperties().setText("Male/Female Ratio Per Dept.");
chart.getChartTitle().getTextProperties().isCentered(true);
chart.getChartTitle().setHeight(25f);
chart.hasTitle(true);
//Set the series label
chart.getSeries().setSeriesLabel(chart.getChartData().get("B1","C1"));
//Set the category labels
chart.getCategories().setCategoryLabels(chart.getChartData().get("A2","A5"));
//Set the series values
chart.getSeries().get(0).setValues(chart.getChartData().get("B2","B5"));
chart.getSeries().get(1).setValues(chart.getChartData().get("C2", "C5"));
//Apply built-in chart style
chart.setChartStyle(ChartStyle.STYLE_11);
//Set overlap
chart.setOverLap(-50);
//Set gap width
chart.setGapWidth(200);
//Save to file
presentation.saveToFile("output/Chart.pptx", FileFormat.PPTX_2013);

Suppose there are two PowerPoint documents, and you want to copy a certain slide from one document to a specified location of the other. Manual copying and pasting is an option, but the quicker and more efficient way is to use Java codes for automatic operation. This article will show you how to programmatically copy slides between two different PowerPoint documents using Spire.Presentation for Java.
Install Spire.Presentation for Java
First of all, you're required to add the Spire.Presentation.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Copy Slides Between Two PowerPoint Documents
The following are detailed steps to copy a slide from one PowerPoint document to a specified position or the end of the other document.
- Create a Presentation object and load one sample document using Presentation.loadFromFile() method.
- Create another Presentation object and load the other sample document using Presentation.loadFromFile() method.
- Get a specific slide of document one using Presentation.getSlides().get() method and insert its copy into the specified position of document two using Presentation.getSlides().insert() method.
- Get another specific slide of document one using Presentation.getSlides().get() method and add its copy to the end of document two using Presentation.getSlides().append() method.
- Save the document two to another file using Presentation.saveToFile() method.
- Java
import com.spire.presentation.FileFormat;
import com.spire.presentation.Presentation;
public class CopySlidesBetweenPPT {
public static void main(String[] args) throws Exception {
//Create a Presentation object to load one sample document
Presentation pptOne= new Presentation();
pptOne.loadFromFile("C:\\Users\\Test1\\Desktop\\sample1.pptx");
//Create another Presentation object to load the other sample document
Presentation pptTwo = new Presentation();
pptTwo.loadFromFile("C:\\Users\\Test1\\Desktop\\sample2.pptx");
//Insert the specific slide from document one into the specified position of document two
pptTwo.getSlides().insert(0,pptOne.getSlides().get(0));
//Append the specific slide of document one to the end of document two
pptTwo.getSlides().append(pptOne.getSlides().get(3));
//Save the document two to another file
pptTwo.saveToFile("output/CopySlidesBetweenPPT.pptx", FileFormat.PPTX_2013);
}
