What Java APIs are best for simple and advanced CSV file manipulation?

CSV API Recommendations for Java

Initial Question:

A user seeks guidance on simple API options for reading, manipulating, and writing CSV files in Java.

Recommended APIs:

1. OpenCSV

A popular and lightweight API suggested by another user:

import au.com.bytecode.opencsv.CSVReader;

// Example usage:

String fileName = "data.csv";
CSVReader reader = new CSVReader(new FileReader(fileName));

// Read header (if any)
String[] header = reader.readNext();

// Read and process data lines
String[] line;
while ((line = reader.readNext()) != null) {
    // Perform desired transformations on line
}

2. Flatpack

The API mentioned in the original post, also offers versatile features for handling CSVs.

Additional Options:

• SuperCSV: A feature-rich CSV parser that provides advanced capabilities such as custom field types and annotations.
• CSV-Parser: A fast and flexible library that supports both CSV reading and writing.
• Apache Commons CSV: A widely used library that provides an intuitive and efficient interface for working with CSVs.
• JXL: An established API for manipulating Excel files, which can also handle CSV files.

The choice of API ultimately depends on the specific requirements of the project. OpenCSV is a good starting point for simple tasks, while other libraries may better suit more advanced scenarios.
