Merging spreadsheets is a common task in various business processes, app development, and data analysis workflows. Think of a scenario where you have multiple Excel files that contain data from different departments or teams, and you need to combine them into a single, unified document. Manually copying and pasting data can be time-consuming and prone to errors. In this article, you will explore merging multiple Excel spreadsheets using the Cloud Java document merger library.

Steps to Merge Excel Spreadsheets using Java REST API

1. Sign up and get your API credentials from the GroupDocs Cloud Dashboard
2. Download the GroupDocs.Merger Cloud Java SDK and create a Java project
3. Initialize the Configuration class to set up your API credentials
4. To merge Excel spreadsheets, instantiate a DocumentApi class object
5. Configure the source Excel files using FileInfo and JoinItem
6. Apply the joining options, such as the output file with JoinOptions
7. Process the request to join two Excel spreadsheets

Using the Cloud API to combine Excel workbooks in Java significantly reduces the complexity of traditional methods. Developers can automate the spreadsheet merging process, making it faster, more reliable, and scalable. You will experience reduced code complexity, as it only takes calling a few API functions rather than writing complex scripts to join your Excel files easily. The Java REST API is platform-independent, making it easy to integrate into any Java-based application.
