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.

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.

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();
   }
}
