Convert XLTM to XLSX (Excel)

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 XLSX file extension, standing for "Excel Spreadsheet", represents a widely used format for Microsoft Excel spreadsheets. Introduced in Excel 2007, XLSX replaced the older XLS format, utilizing the Office Open XML (OOXML) standard to store data more efficiently and reduce file size. It supports advanced features such as pivot tables, charts, formulas, and macros, essential for data analysis and reporting in various professional settings. The transition to XLSX provided enhanced security, improved data recovery, and greater compatibility with other software applications, solidifying its status as a pivotal tool in data management and business intelligence.
