Processing spreadsheets could mean juggling multiple Excel XLS files that store related data across departments or projects. As these files grow, keeping everything aligned can turn into a slow and error-prone task. You can simplify this process by combining the XLS files into a single spreadsheet that brings all your data together in one place. In this article, we’ll look at how to merge XLS files in Node.js programmatically using a REST-based API. By consolidating multiple Excel spreadsheets into a single file, you can maintain clearer records, reduce duplication, and make data easier to review or share.

Steps to Merge XLS Files Using Node.js

1. Import and set up GroupDocs.Merger Cloud SDK for Node.js
2. Obtain API credentials and initialize the DocumentApi with them
3. Configure the source XLS files to merge from the cloud storage
4. Define the XLS merging options with JoinOptions
5. Create an XLS file joining request using JoinRequest
6. Process the request to merge two XLS files using the join() method

The Node.js REST API enables a straightforward way to merge Excel XLS files without relying on desktop spreadsheet software. You simply provide the XLS files you want to combine, define the merge order, and generate a single output file. The process runs securely in the cloud, eliminating the need for repetitive manual work. This Node.js document merger workflow is useful for teams that frequently update spreadsheets or receive XLS files from multiple sources. Developers can automate the merge process to save time and ensure that all spreadsheet data stays centralized and easier to manage.
