Accurately Compare CSV Files in Java using Cloud REST API

Manually comparing CSV files can be a tedious, error-laden, and frustrating task—especially when handling intricate datasets or large data imports. With the GroupDocs.Comparison Cloud Java SDK, automating the comparison of CSV files and integrating it effortlessly into your Java applications requires only a few API calls.

This efficient and robust Java REST API enables you to programmatically identify differences between CSV files—accurately highlighting added and removed content. Whether you're overseeing data validation in ETL processes, implementing version control for tabular information, or creating tools for automated quality assurance checks, this SDK provides the precision and performance that contemporary Java applications need.

With the flexibility of cloud-native solutions, there's no need to be concerned about local installations or platform-specific requirements. Simply authenticate your application, invoke the API, and obtain clear, structured difference results between CSV files. This Cloud SDK is essential for Java developers engaged in document automation, enterprise integration, or data-centric systems. You can follow our detailed tutorial to get up and running right away.

Incorporate this capability into your Java applications by reviewing the following example of Java code:

package com.groupdocs;
import com.groupdocs.cloud.comparison.client.*;
import com.groupdocs.cloud.comparison.api.*;
import com.groupdocs.cloud.comparison.model.*;
import com.groupdocs.cloud.comparison.model.requests.*;

public class CompareCSVfiles {
    public static void main(String[] args) {

        // Initialize API client with client ID and client secret
        String MyClientId = "your-client-id";
        String MyClientSecret = "your-client-secret";
        Configuration configure = new Configuration(MyClientId, MyClientSecret);

        // Create an instance of CompareApi
        CompareApi comparisonApi = new CompareApi(configure);

        // Set up the FileInfo object for the source CSV file
        FileInfo sourceFile = new FileInfo();

        // Source file path in cloud storage
        sourceFile.setFilePath("SampleFiles/source.csv");

        // Set up the FileInfo object for the target CSV file
        FileInfo targetFile = new FileInfo();

        // Target file path in cloud storage
        targetFile.setFilePath("SampleFiles/target.csv");

        // Create and set up the ComparisonOptions object
        ComparisonOptions options = new ComparisonOptions();
        options.setSourceFile(sourceFile);
        options.addTargetFilesItem(targetFile);

        // Specify output path in cloud storage
        options.setOutputPath("comparison/compared.csv");

        try {

            // Create the comparisons request
            ComparisonsRequest request = new ComparisonsRequest(options);
            // Perform the comparison and get the response
            Link response = comparisonApi.comparisons(request);

        } catch (ApiException e) {

            System.err.println("Exception occurred: " + e.getMessage());
        }
    }
}
