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.

OTP

Origin Graph Template

The OTP (OpenDocument Presentation Template) file format is a standardized template format used for creating presentations within the OpenDocument family of file formats, maintained by the Organization for the Advancement of Structured Information Standards (OASIS). It is primarily supported by open-source office suites like LibreOffice and Apache OpenOffice, as well as other applications that adhere to the OpenDocument standard. The format is based on XML and supports advanced features such as embedded multimedia, customizable slide layouts, and compatibility with other presentation formats like PPT and PPTX through conversion tools.
