XLTX

Microsoft Excel Open XML Template

XLTX is a file format used for Excel Open XML Spreadsheet Templates, designed to store pre-formatted spreadsheet layouts for creating consistent and reusable Excel documents. It is supported by Microsoft Excel, LibreOffice Calc, and other spreadsheet applications, enabling users to create, edit, and share templates across platforms. The format is based on XML and ZIP compression, allowing for structured data storage, advanced formatting, and customization options such as formulas, styles, and macros.

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.
