Combine Word using JavaScript REST API

Easily merge Word files together in JavaScript code. This JavaScript library is designed to combine multiple Word files into a single file using the REST API, i.e. by passing HTTPS calls over the Internet.

This is a professional Cloud-native Word merging solution that provides JavaScript programmers with both great development flexibility and powerful features. Joining Word files together is often used when it is necessary to create a set of documents of the same structure, each of which contains unique data. By merging Word files, you can automate your digital workflows and offload some routine parts of the process to fast and efficient Word processing JavaScript software.

Merge multiple Word into one in JavaScript

You may need to combine Word files together in many cases. For example, you may want to combine multiple Word files together before printing or archiving.

Word merging can be part of a whole integrated document-processing approach for generating documents from disparate data sources. Such tasks involve the use of a full-featured Word manipulation JavaScript library that will process a set of Word files and merge them together in the shortest possible time, producing a compact and accurate result.

Merge Word files in JavaScript

To merge Word in JavaScript, you need at least two source Word files. For a quick start, please check out the JavaScript code example below.

Upload files you want to combine
Run code
Upload files you want to combine
Select the target format from the list
import * as fs from "fs";

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

const document = fs.createReadStream("Input1.docx");
// Load a document to append from the Cloud storage.
const mergeDocument = new model.DocumentEntry({
    fileReference: model.FileReference.fromRemoteFilePath("Input2.docx"),
    importFormatMode: "KeepSourceFormatting"
})

const documentEntries = [ mergeDocument ]
const documentList = new model.DocumentEntryList({
    documentEntries: documentEntries
})

const appendDocumentOnline = new model.AppendDocumentOnlineRequest({
    document: document,
    documentList: documentList
});
wordsApi.appendDocumentOnline(appendDocumentOnline)
.then((appendDocumentOnlineResult) => {
    console.log("Result of AppendDocumentOnline: ", appendDocumentOnlineResult);
});
