Split an excel to multiple excel files in Java

In this blog we will see how to split an excel into multiple excel files using Apache POI library. Apache POI provides a comprehensive set of APIs for more advanced operations on Excel and Word documents, making it a powerful tool for handling office documents in Java applications.

Apache POI (Poor Obfuscation Implementation) is a popular open-source Java library provided by the Apache Software Foundation for working with Microsoft Office documents, particularly Excel and Word files. It allows developers to create, read, and manipulate Excel (.xls and .xlsx) and Word (.doc and .docx) documents programmatically using Java code.

Here are some key features and components of Apache POI:

• HSSF: Stands for Horrible Spreadsheet Format. It is used for reading and writing Excel 97-2003 (.xls) files.
• XSSF: Stands for XML Spreadsheet Format. It is used for reading and writing Excel 2007 and later (.xlsx) files, which are based on XML.
• HWPF: Stands for Horrible Word Processor Format. It is used for reading and writing Word 97-2003 (.doc) files.
• XWPF: Stands for XML Word Processor Format. It is used for reading and writing Word 2007 and later (.docx) files, which are also based on XML.
• HSLF: Stands for Horrible Slide Layout Format. It is used for reading and writing PowerPoint (.ppt) files.
• XSLF: Stands for XML Slide Layout Format. It is used for reading and writing PowerPoint 2007 and later (.pptx) files.
