Spire.Cloud.Word offers the replaceTextApi interface to replace old text in a Word document with new text. This tutorial will show you how to do it programmatically using Java codes.

import spire.cloud.word.sdk.client.ApiException;
import spire.cloud.word.sdk.client.Configuration;
import spire.cloud.word.sdk.client.api.ReplaceTextApi;

public class ReplaceText {
    static String appId = "App ID";
    static String appKey = "App Key";
    static String baseUrl = "https://api.cloudxdocs.com";
    //Create a configuration object based on your App ID and App Key
    static Configuration wordConfiguration = new Configuration(appId, appKey, baseUrl);
    //Create a replaceTextApi instance
    static ReplaceTextApi replaceTextApi = new ReplaceTextApi(wordConfiguration);

    public static void main(String[] args) throws ApiException {
        //Load a sample file
        String name = "Sample.docx";
        //Specify the old text to be replaced
        String oldValue = "Doc";
        //Specify the new text used to replace the old text in the sample
        String newValue = "Word";
        //Specify the password of the sample, it's null if nothing
        String password = null;
        //Specify the folder storing the sample, it's null if nothing
        String folder = "input";
        //Use the 2G storage provided by E-iceblue, it's null by default
        String storage = null;
        Boolean matchCase = false;
        Boolean matchWholeWord = null;
        Boolean replaceFirst = null;
        //Specify the storage path of the resulting document
        String destFilePath = "output/ReplaceWithText.docx"; ;
        //Call the replaceWithText method to replace the old text in the sample with new text
        replaceTextApi.replaceWithText(name, oldValue, newValue, destFilePath, password, folder, storage, matchCase, matchWholeWord, replaceFirst);
    }
}
