CsvMapper

CsvMapper is a Java utility class that provides methods for parsing and writing CSV (Comma-Separated Values) files using a specified regex. It utilizes the Selcukes collections library to streamline the data processing.

Introduction

The CsvMapper class is designed to simplify the reading and writing of CSV files. It offers methods to parse a CSV file into a DataTable and to write DataTable or CSV data to a CSV file. The default CSV parsing regex is provided, and you can also specify a custom regex if needed.

Parsing CSV Files

Method 1: Using Default Regex

Path filePath = Paths.get("path/to/your/file.csv");
DataTable<String, String> dataTable = CsvMapper.parse(filePath);

Method 2: Using Custom Regex

Path filePath = Paths.get("path/to/file.csv");
DataTable<String, String> dataTable = CsvMapper.parse(filePath, CsvMapper.CSV_REGEX);

Writing to CSV Files

Method 1: Writing DataTable to CSV File

Path filePath = Paths.get("path/to/your/output.csv");
DataTable<String, String> dataTable = CsvMapper.write(filePath, dataTable); // create or obtain your DataTable

Method 2: Writing CSV Data to File

Path filePath = Paths.get("path/to/your/output.csv");
String csvData = CsvMapper.write(filePath, csvData); // create or obtain your CSV data as a string

note

In case of errors during file parsing or writing, a DataMapperException is thrown. This exception provides information about the failure, including the underlying cause.
