Merge Word Documents Using Node.js

This section explains the details on how to merge MS Word documents using Node.js API.

Step 1 – Initialize the API:

const { WordsApi, AppendDocumentRequest, Configuration } = require("asposewordscloud");

const config = new Configuration("YOUR_CLIENT_ID", "YOUR_CLIENT_SECRET");
const wordsApi = new WordsApi(config);

Step 2 – Create Merge Request:

const appendDocs = {
  DocumentEntries: [
    {
      Href: "secondFile.docx",
      ImportFormatMode: "KeepSourceFormatting"
    }
  ]
};

const request = new AppendDocumentRequest({
  name: "mainFile.docx",
  documentEntries: appendDocs,
  destFileName: "MergedOutput.docx"
});

Step 3 – Perform the Merge Operation:

wordsApi.appendDocument(request)
  .then(response => console.log("Documents merged successfully:", response.body))
  .catch(error => console.error("Merge failed:", error));

Merge DOCX Files Using cURL

With the help of cURL commands, you eliminate the effort of creating complex code snippet. In this section, we are going to learn the details on how to perform the MS Word documents merge operation using REST API and cURL commands.

Step 1 – Generate Access Token:

curl -v "https://api.aspose.cloud/connect/token" \
 -X POST \
 -d "grant_type=client_credentials&client_id=CLIENT_ID&client_secret=CLIENT_SECRET" \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Accept: application/json"

Step 2 – Combine Word Files with cURL:

curl -v -X PUT "https://api.aspose.cloud/v4.0/words/{FirstFile}/appendDocument?destFileName=MergedFile.docx" \
-H  "accept: application/json" \
-H  "Authorization: Bearer <JWT Token>" \
-H  "Content-Type: application/json" \
-d "{\"DocumentEntries\":[{\"Href\":\"{SecondFile}\",\"ImportFormatMode\":\"KeepSourceFormatting\"}],\"ApplyBaseDocumentHeadersAndFootersToAppendingDocuments\":true}"
  • Make sure both input files (FirstFile and SecondFile) are uploaded to your cloud storage beforehand.
