Edit DOCX in Node SDK

Use REST API to edit DOCX in JavaScript programmatically

When developers modify a DOCX document with this JavaScript library, what is actually being edited is the Document Object Model (DOM). Thus, almost any changes can be made to the DOCX document represented as DOM. With the provided Node SDK, developers can easily edit a document: modify text, update tables, add images and so on. Just load a DOCX, make the necessary changes programmatically and export the result to the same or any supported save format.

Edit DOCX in JavaScript using REST API

Our Node library gives developers the ability to modify a DOCX document directly by editing its Document Object Model (DOM), which means no additional software needs to be installed.

Edit text in DOCX file using JavaScript

The most popular case to edit a DOCX file is text editing. With the given software solution, you can add, modify or delete text using JavaScript within the document.

Edit table in DOCX file using JavaScript

Another popular DOCX editing option is table editing. Our Node SDK allows you to work with tables and text in table cells.

JavaScript developers can add or remove table and table cells, as well as add, edit and remove text within them.

Add an image to DOCX file using JavaScript

Besides editing text and tables in DOCX, there is another common option: adding images to a document in JavaScript. Node developers can also add an image into a DOCX file using DOM.

Edit DOCX programmatically

Try this powerful Node SDK and evaluate some options in DOCX document editing. Using the following example, load your DOCX document and make some changes: add text, add a table and a table cell with text or insert an image into the DOCX document:

Upload a document you want to modify
Run code
Upload an image you want insert
Select the target format from the list
import * as fs from "fs";

const wordsApi = new WordsApi("####-####-####-####-####", "##################");

const requestDocument = fs.createReadStream("Input.docx");
const requestParagraph = new model.ParagraphInsert({
    text: "Morbi enim nunc faucibus a."
})
const insertParagraphRequest = new model.InsertParagraphOnlineRequest({
    document: requestDocument,
    paragraph: requestParagraph
});

wordsApi.insertParagraphOnline(insertParagraphRequest)
.then((insertParagraphResult) => {    
    const requestDocument = insertParagraphResult.Document.Values();
    const convertDocument = new model.ConvertDocumentRequest({
        document: requestDocument,
        format: "docx"
    });

    wordsApi.convertDocument(convertDocument)
    .then((convertDocumentResult) => {
        console.log("Result of ConvertDocument: ", convertDocumentResult);
    });
});
import * as fs from "fs";

const wordsApi = new WordsApi("####-####-####-####-####", "##################");

const requestDocument = fs.createReadStream("Input.docx");
const requestTable = new model.TableInsert({
    columnsCount: 1,
    rowsCount: 2
})
const insertTableRequest = new model.InsertTableOnlineRequest({
    document: requestDocument,
    table: requestTable,
    nodePath: ""
});

wordsApi.insertTableOnline(insertTableRequest)
.then((insertTableResult) => {    
    const requestDocument = insertTableResult.Document.Values();
    const convertDocument = new model.ConvertDocumentRequest({
        document: requestDocument,
        format: "docx"
    });

    wordsApi.convertDocument(convertDocument)
    .then((convertDocumentResult) => {
        console.log("Result of ConvertDocument: ", convertDocumentResult);
    });
});
import * as fs from "fs";

const wordsApi = new WordsApi("####-####-####-####-####", "##################");

const requestDocument = fs.createReadStream("Input1.docx");
const requestDrawingObject = new model.DrawingObjectInsert({
    height: 0,
    left: 0,
    top: 0,
    width: 0,
    relativeHorizontalPosition: model.DrawingObjectInsert.RelativeHorizontalPositionEnum.Margin,
    relativeVerticalPosition: model.DrawingObjectInsert.RelativeVerticalPositionEnum.Margin,
    wrapType: model.DrawingObjectInsert.WrapTypeEnum.Inline
})
const requestImageFile = fs.createReadStream("Input2.docx");
const insertDrawingObjectRequest = new model.InsertDrawingObjectOnlineRequest({
    document: requestDocument,
    drawingObject: requestDrawingObject,
    imageFile: requestImageFile,
    nodePath: "sections/0"
});

wordsApi.insertDrawingObjectOnline(insertDrawingObjectRequest)
.then((insertDrawingObjectResult) => {    
    const requestDocument = insertDrawingObjectResult.Document.Values();
    const convertDocument = new model.ConvertDocumentRequest({
        document: requestDocument,
        format: "docx"
    });

    wordsApi.convertDocument(convertDocument)
    .then((convertDocumentResult) => {
        console.log("Result of ConvertDocument: ", convertDocumentResult);
    });
});
