Java Convert Csv to Excel File Example

Date: 2018-01-03

This tutorial demonstrates converting CSV files to Excel using Apache POI's SXSSF library in Java. SXSSF is ideal for large files due to its low memory footprint, achieved by processing rows in a sliding window and writing older rows to disk. The tutorial guides users through creating a Maven project in Eclipse, adding necessary dependencies (Apache POI, OpenCSV), and implementing the conversion logic in Java classes. It provides a step-by-step process, including screenshots, to build and run the application. The resulting Excel file is saved to the project's configuration folder. This approach avoids java.lang.OutOfMemoryError exceptions often encountered when processing large CSV files.
