Compare CSV Files using Java REST API

CSV is a widely adopted format for data interchange in modern business apps. Identifying the differences may become challenging when two CSV datasets diverge due to versioning, data source updates, or user input. Considering manual comparison is slow and error-prone, automating the CSV file comparison improves accuracy and significantly reduces development effort. This guide analyzes how to compare CSV files in Java and enables reliable diff-checking using the Java REST API.

Steps to Compare CSV Files Using Java

  1. Download the GroupDocs.Comparison Cloud Java SDK and create a Java project
  2. Obtain and set up your API credentials with the Configuration class
  3. Initialize the CompareApi class for comparison
  4. Create FileInfo objects for the source and target CSV files
  5. Define comparison options with the ComparisonOptions class
  6. Load & execute the CSV file comparison request with the comparisons method

The comparison process starts by configuring the Cloud Java SDK and setting up your credentials. Then, you instantiate the comparison API, add source and target CSV files, define comparison options, and execute the request to compare two CSV documents. Tailored for Java, the Cloud API offers native integration into your apps and works across desktop or cloud environments. You require minimal code while building automated CSV comparison tools and enjoy total control over your logic, files, and cloud operations.
