Convert XLSM to XLSX (Excel)

The XLSM file extension stands for Microsoft Excel Macro-Enabled Spreadsheet. It allows users to automate tasks via macros, enhancing productivity in complex data manipulation and repetitive operations. Introduced with Excel 2007 as part of the Office Open XML format, XLSM files support the embedding of VBA (Visual Basic for Applications) macros within spreadsheets. This format offers advanced functionalities for financial analysis, data modeling, and automation within the Microsoft Excel environment, optimizing efficiency for professional use.

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.
