VSTX

Microsoft Visio File Format

The VSTX file format is a template file used by Microsoft Visio, a diagramming and vector graphics application, to store predefined settings, layouts, and shapes for creating diagrams. It is primarily used with Microsoft Visio but can also be opened by other diagramming tools like Lucidchart or LibreOffice Draw with limited compatibility. The format is based on the Open Packaging Conventions (OPC) and stores XML-based data, enabling advanced features such as custom stencils, themes, and reusable templates for streamlined diagram creation.

XLSB

Microsoft Excel Binary Spreadsheet File

XLSB is a binary file format used by Microsoft Excel to store spreadsheet data, offering a more compact and efficient alternative to XML-based formats like XLSX. It is primarily supported by Microsoft Excel and a few third-party tools, such as LibreOffice and Apache POI, though compatibility may vary. The format stores data in a compressed binary structure, enabling faster loading and saving times, and supports advanced Excel features like macros, charts, and complex formulas while maintaining smaller file sizes compared to XML-based formats.
