Join documents together using Node

Node Cloud SDK to combine several documents and export the result to almost any office format

Use Node library to merge Word, PDF, Web documents via REST API. Easily combine two or more documents into a single file using Node.

Combine Word, PDF, Web documents using Node REST API

Easily merge documents together in various formats in Node code. This Node library is designed to combine Word, PDF, Web documents into a single file using the REST API, i.e. by passing HTTPS calls over the Internet.

This is a professional Cloud-native document-merging solution that provides Node programmers with both great development flexibility and powerful features. Joining 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 documents, you can automate your digital workflows and offload some routine parts of the process to fast and efficient document-processing Node software.

Merge multiple files into one in Node

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

Merging documents together can be part of a whole integrated technology for creating documents from disparate data sources. Such tasks involve the use of a full-featured file format manipulation Node library that will process sets of files and merge them together in the shortest possible time, creating a compact and accurate output.

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

Node code example to merge documents using REST API
Input files
Upload files you want to combine
Upload files you want to combine
Output format
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({
    href: "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);
});
