Convert VDW to XLSX in Java

What is VDW file format?

The VDW file format, also known as Visual Datafile, is a database file format used predominantly by database programs developed for the Windows operating system. It is also used by many other programs that require database functionality. The VDW format is based on the older Paradox database format and is easily compatible with Paradox databases. Like Paradox databases, VDW files are organized into tables and can contain a variety of data fields. The data fields can include text, numbers, images and binary data. VDW files are stored in a binary format, which makes them fast and efficient to process. However, the binary files are not human-readable, so they must be opened with a database program that can interpret the data. The VDW file format is supported by several database programs, including Microsoft Access, Corel Paradox, and OpenOffice.org Calc. It is also used by some programs for spreadsheet and graphics applications. Overall, the VDW file format provides a versatile and efficient way to store and access data in a database. It is widely used across many different types of software applications and is a popular choice for database-driven programs.

What is XLSX file format?

The XLSX file format is a widely used file format for storing spreadsheet data. It was introduced by Microsoft as part of their Microsoft Office suite, specifically for the Excel application. XLSX stands for Excel Open XML Spreadsheet. Unlike its predecessor, the XLS format, which was based on a proprietary binary file structure, XLSX is based on the Open XML file format.

XLSX files are structured as a collection of XML files compressed into a single ZIP archive. This XML-based structure allows for more efficient storage and faster data processing. XLSX files store data in a tabular format, with rows and columns that can contain text, numbers, formulas, and other types of data. They also support formatting options such as cell styles, fonts, colors, and conditional formatting.

One of the advantages of the XLSX format is its compatibility across different platforms and software applications. Many spreadsheet programs, including Microsoft Excel, Google Sheets, and LibreOffice Calc, can open and edit XLSX files. This makes it easy to share and collaborate on spreadsheet data with others, regardless of the software they are using.

XLSX files also offer features like data validation, filtering, sorting, and the ability to create charts and graphs based on the data. Additionally, XLSX files can contain multiple sheets within a single file, allowing users to organize and manage different sets of data within a single document.
