XLSX

Microsoft Excel Open XML Spreadsheet

XLSX is a widely used file format for spreadsheets, developed by Microsoft as part of the Office Open XML standard, succeeding the older XLS format. It is supported by Microsoft Excel, Google Sheets, LibreOffice Calc, and other spreadsheet applications, ensuring cross-platform compatibility. The format is based on XML and stored in a compressed ZIP container, enabling features like advanced formulas, charts, conditional formatting, and support for large datasets while maintaining smaller file sizes compared to its predecessor.

DOTM

Microsoft Word Macro-Enabled Template

The DOTM file format is a macro-enabled document template used in Microsoft Word, allowing users to create standardized documents with predefined formatting and content. It is primarily supported by Microsoft Word and other compatible office suites like LibreOffice and Apache OpenOffice, enabling the creation and editing of templates with embedded macros. The format is based on the Open XML standard, featuring a zipped package of XML files that define document structure, styles, and embedded VBA macros for automation and advanced functionality.
