What Java Library Simplifies CSV Reading, Parsing, Validation, and Mapping to Java Objects?

Java Library for CSV Manipulation: OpenCSV

For seamless reading, parsing, validation, and mapping of CSV files to Java value objects, the OpenCSV library emerges as a robust option. Developed by the OpenSource community, OpenCSV provides an extensive feature set to handle complex CSV operations effectively.

Reading and Parsing CSV Files

To initiate reading, simply construct a CSVReader object, providing the input source as a file or stream. The reader allows for line-by-line iteration through each row of the CSV file.

Validation

Ensuring data integrity is crucial. OpenCSV empowers you to validate the CSV file contents against predefined rules, such as data type restrictions, required fields, and value ranges. This functionality helps identify errors early on, enhancing data quality.

Mapping to Java Value Objects

One of OpenCSV's key strengths is its ability to map CSV rows to Java value objects (JavaBeans). Leveraging this feature, you can seamlessly convert raw data into structured objects, enabling further processing and manipulation.
