Prerequisites

Before diving into this tutorial, ensure you have the following prerequisites:

• Java Development Kit (JDK) installed on your system.
• Basic understanding of Java programming language.
• IDE (Integrated Development Environment) such as IntelliJ IDEA or Eclipse.
• Aspose.Slides for Java library, which you can download from here.

Import Packages

First, you need to import necessary packages from Aspose.Slides for Java to begin working with PowerPoint presentations in your Java project:

import com.aspose.slides.*;
import java.awt.Color;

Step 1: Load the Presentation

To start, load the PowerPoint presentation where you want to perform the text replacement.

String presentationName = "Your Document Directory";
Presentation pres = new Presentation(presentationName);

Replace "Your Document Directory" with the actual path to your PowerPoint file.

Step 2: Define Output Path

Specify the output path where the modified presentation will be saved after text replacement.

String outPath = "Your Output Directory" + "TextReplaceExample-out.pptx";

Replace "Your Output Directory" with the directory where you want to save the modified presentation.

Step 3: Set Text Replacement Format

Define the format for the replaced text, such as font size, style, and color.

PortionFormat format = new PortionFormat();
format.setFontHeight(24f);
format.setFontItalic(NullableBool.True);
format.getFillFormat().setFillType(FillType.Solid);
format.getFillFormat().getSolidFillColor().setColor(Color.RED);

Modify these attributes (setFontHeight, setFontItalic, setFillColor, etc.) according to your specific formatting needs.

Step 4: Perform Text Replacement

Use Aspose.Slides APIs to find and replace text within the slides.

SlideUtil.findAndReplaceText(pres, true, "[this block] ", "my text", format);

Replace "my text" with the text you want to replace and "[this block] " with the text you want to find in the presentation.

Step 5: Save the Modified Presentation

Save the modified presentation to the specified output path.

pres.save(outPath, SaveFormat.Pptx);

Step 6: Clean Up Resources

Dispose of the Presentation object to release resources.

if (pres != null) pres.dispose();
