[Java] Find and Replace Text in Word Documents

When manipulating a Word document, sometimes we may encounter a situation where we need to replace the specified text with new text. In this articel, I will introduce 2 ways to find and replace text by using Free Spire.Doc for Java .
1. Find and replace all matched text with new text.
2. Find and replace the first matched text with new text.

Installation
Method 1: Download the Free Spire.Doc for Java and unzip it. Then add the Spire.Doc.jar file to your Java application as dependency.

Method 2: You can also add the jar dependency to maven project by adding the following configurations to the pom.xml.

<repositories>
   <repository>
      <id>com.e-iceblue</id>
      <name>e-iceblue</name>
      <url>http://repo.e-iceblue.com/nexus/content/groups/public/</url>
   </repository>
</repositories>
<dependencies>
   <dependency>
      <groupId>e-iceblue</groupId>
      <artifactId>spire.doc.free</artifactId>
      <version>3.9.0</version>
   </dependency>
</dependencies>

The original document is shown as below：

【Example 1】Replaces all of the “Nathanial Hawthorne” text with “Herman Melville” by using the replace method.

import com.spire.doc.*;

public class ReplaceText {
    public static void main(String[] args){
        //Load the Word document
        Document document = new Document("Herman.docx");

        //Replace the specified text with new text 
        document.replace("Nathanial Hawthorne", "Herman Melville", false, true);

        //Save the document
        document.saveToFile("ReplaceAllMatchedText.docx", FileFormat.Docx_2013);
    }
}

Output:

【Example 2】Replaces the first “Nathanial Hawthorne” text with “Herman Melville” by using the setReplaceFirst method.

import com.spire.doc.*;

public class ReplaceText {
    public static void main(String[] args){
        //Load the Word document
        Document document = new Document("Herman.docx");

        //Replace the first matched text
        document.setReplaceFirst(true);

        //Replace with new text
        document.replace("Nathanial Hawthorne", "Herman Melville", false, true);

        //Save the document
        document.saveToFile("ReplaceFirstMatchedText.docx", FileFormat.Docx_2013);
    }
}

Output:
