Spire.Cloud.Word provides developers with the ParagraphsApi interface to manipulate paragraphs in Word documents. This article will introduce how to add, replace and delete paragraphs in Word Document with this interface.

The original Word document is shown as below:

Add a paragraph

import spire.cloud.word.sdk.client.*;
import spire.cloud.word.sdk.client.api.ParagraphsApi;

public class addParagraph {
    static String appId = "APP ID";
    static String appKey = "APP Key";
    static String baseUrl = "https://api.cloudxdocs.com";

    //Create a Configuration object based on App ID, App Key and base Url
    static Configuration wordConfiguration = new Configuration(appId, appKey, baseUrl);
    //Create an instance of ParagraphsApi
    static ParagraphsApi paragraphsApi = new ParagraphsApi(wordConfiguration);

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

        //Specify the name of the original Word document
        String fileName = "Spire.Office.docx";
        String name = fileName;

        //Add a paragraph
        String nodePath = "Section/0/Body/0";
        Integer indexOfParagraph = 1;
        String text = "This is a newly added paragraph";

        //Specify the folder where the original document is stored, set it to null if there's none
        String folder = "input";
        //Specify the original password of the input document, set it to null if there's none
        String password = null;
        //Store the document in the 2G default storage space offered by E-iceblue Cloud
        String storage = null;
        //Specify the storage path and name of the generated document
        String destFilePath = "output/AddParagraph.docx";

        //Add a paragraph to the Word document with "addParagraph" method
        paragraphsApi.addParagraph(name, nodePath, destFilePath, folder, storage, indexOfParagraph, password, text);
    }
}

import spire.cloud.word.sdk.client.*;
import spire.cloud.word.sdk.client.api.ParagraphsApi;

public class updateParagraphText {
    static String appId = "APP ID";
    static String appKey = "APP Key";
    static String baseUrl = "https://api.cloudxdocs.com";

    //Create a Configuration object based on App ID, App Key and base Url
    static Configuration wordConfiguration = new Configuration(appId, appKey, baseUrl);
    //Create an instance of ParagraphsApi
    static ParagraphsApi paragraphsApi = new ParagraphsApi(wordConfiguration);

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

        //Specify the name of the original Word document
        String fileName = "Spire.Office.docx";
        String name = fileName;

        //Replace the text in the third paragraph
        String nodePath = "Section/0/Body/0";
        Integer index = 2;
        String text = "A Brief Introduction of Spire.Office";

        //Specify the folder where the original document is stored, set it to null if there's none
        String folder = "input";
        //Specify the original password of the input document, set it to null if there's none
        String password = null;
        //Store the document in the 2G default storage space offered by E-iceblue Cloud
        String storage = null;
        //Specify the storage path and name of the generated document
        String destFilePath = "output/UpdateParagraphText.docx";

    }
}

import spire.cloud.word.sdk.client.api.ParagraphsApi;

public class deleteParagraph {
    static String appId = "APP ID";
    static String appKey = "App Key";
    static String baseUrl = "https://api.cloudxdocs.com";

    //Create a Configuration object based on App ID, App Key and base Url
    static Configuration wordConfiguration = new Configuration(appId, appKey, baseUrl);
    //Create an instance of ParagraphsApi
    static ParagraphsApi paragraphsApi = new ParagraphsApi(wordConfiguration);

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

        //Specify the name of the original Word document
        String fileName = "Spire.Office.docx";
