Convert XLTM to OTS

An XLTM file, short for Excel Macro-Enabled Spreadsheet Template, is a Microsoft Excel file extension used for templates that include macros. These templates allow users to automate repetitive tasks, format documents, and perform complex calculations. XLTM files store settings, layout information, and spreadsheet data, enabling users to create multiple spreadsheets with consistent formatting and functionality. Introduced by Microsoft, XLTM files are essential for users who need to streamline their workflow and ensure uniformity across multiple documents.

The OTS (OpenDocument Spreadsheet Template) file extension, maintained by the Organization for the Advancement of Structured Information Standards (OASIS), is used to create spreadsheet templates with predefined styles and formatting in Apache OpenOffice Calc. Introduced in 2005, OTS files facilitate the creation of consistent and reusable templates for tasks like budget planning and invoicing. These files are XML-based, compressed as ZIP archives, and compatible with various open-source spreadsheet applications.
