This article demonstrates how to replace text in an exising PowerPoint document with new text using Spire.Presentation for Java.

import com.spire.presentation.*;

import java.util.HashMap;
import java.util.Map;

public class ReplaceText {

    public static void main(String[] args) throws Exception {

        //create a Presentation object
        Presentation presentation = new Presentation();

        //load the template file
        presentation.loadFromFile("C:\\Users\\Administrator\\Desktop\\input.pptx");

        //get the first slide
        ISlide slide= presentation.getSlides().get(0);

        //create a Map object
        Map map = new HashMap();

        //add several pairs of keys and values to the map
        map.put("#name#","John Smith");
        map.put("#age#","28");
        map.put("#address#","Oklahoma City, United States");
        map.put("#tel#","333 123456");
        map.put("#email#","johnsmith@outlook.com");

        //replace text in the slide
        replaceText(slide,map);

        //save to another file
        presentation.saveToFile("output/ReplaceText.pptx", FileFormat.PPTX_2013);
    }

    /**
     * Replace text within a slide
     * @param slide Specifies the slide where the replacement happens
     * @param map Where keys are existing strings in the document and values are the new strings to replace the old ones
     */
    public static void replaceText(ISlide slide, Map map) {

        for (Object shape : slide.getShapes()
        ) {
            if (shape instanceof IAutoShape) {

                for (Object paragraph : ((IAutoShape) shape).getTextFrame().getParagraphs()
                ) {
                    ParagraphEx paragraphEx = (ParagraphEx)paragraph;
                    for (String key : map.keySet()
                    ) {
                        if (paragraphEx.getText().contains(key)) {

                            paragraphEx.setText(paragraphEx.getText().replace(key, map.get(key)));
                         }
                    }
                }
            }
        }
    }
}
