We will guide you through the step-by-step process to compare Excel files in Java by using one of the best document comparison API in this article. You will learn how to use these steps to create the Java program to compare two excel files. Here you can find the detailed instructions along with a sample code to compare two Excel sheets and highlight differences in Java.

Steps to Compare Excel Files in Java

1. Install GroupDocs.Comparison for Java from the Maven repository in the Java project for Excel files comparison
2. Import essential classes for developing Java compare two excel files functionality
3. Create an instance of the Comparer class and pass the source XLSX file to its constructor
4. Call the add method of the Comparer class and specify the target XLSX file path
5. Finally, call the compare method and pass the resultant XLSX file path for comparison

In the preceding section, we have outlined the steps to compare two Excel files in Java. Comparing two excel sheets in Java can be achieved without installing any third-party tool, with three to four lines of code and consuming a few API calls. You just need to set up the required library from the Maven repository for performing the document comparison.

Code to Compare Excel Files in Java

We have developed a Java code to compare two excel sheets and highlight differences and store the resultant file on the disk. This example shows the implementation of comparing two excel sheets in Java but you can easily compare multiple Excel files by using the add method of the Comparer class. Moreover, you can easily use this sample code for comparison of other Spreadsheet formats like XLS, XLT, XLTM, XLSB, and XLSM.

We have gone over the detailed procedures to compare two excel sheets in Java and produced sample code for it. Recently, we had published an article on comparing CSV files in Java, visit how to Compare CSV Files in Java guide for more information.
