OpenDocument Spreadsheet Template

The OpenDocument Spreadsheet Template (OTS) is a file format used for creating reusable spreadsheet templates based on the OpenDocument standard, primarily for applications like spreadsheets. It is supported by various office suites, including LibreOffice, Apache OpenOffice, and Calligra Suite, enabling users to design and share pre-formatted spreadsheets. The OTS format is XML-based, storing layout, formulas, styles, and other settings, and supports advanced features like macros, conditional formatting, and data validation for efficient template creation and customization.
