| Description | 🔵 The XLSM format is a specific file extension used in Microsoft Excel, denoting a spreadsheet containing macros. These macros are written in the Visual Basic for Applications (VBA) language. This format enhances the traditional XLSX format by including macros, a feature absent in XLSX files. XLSM files allow users to automate tasks, perform calculations, and create custom functions within Excel, using VBA macros. These macros can range from simple scripts to complex automation sequences, streamlining workflows and boosting productivity. XLSM files are commonly used in applications requiring automation and customization, such as business, finance, and data analysis. |
| Technical details | 🔵 XLSM files are built on the Open XML format, a zipped, XML-based file format developed by Microsoft to represent spreadsheets, charts, presentations, and word processing documents. The main components of an XLSM file are XML files, stored within the compressed archive. These XML files define the workbook's structure, styles, themes, and shared strings, dictating the content and formatting of the spreadsheet. XLSM files support macros written in VBA, and these macros can be accessed and modified in Microsoft Excel, as well as other spreadsheet software supporting the Open XML format. The ".xlsm" file extension distinguishes Excel workbooks enabled with macros from standard Excel workbooks, typically denoted by the ".xlsx" extension. This helps users and applications identify files containing macros, while the ".xlsx" extension signifies standard Excel documents without macros. |

| Description | 🔵 The .xls format is synonymous with spreadsheets created in Microsoft Excel, especially in versions prior to 2007. This binary file format has the capability to store data in cells that are systematically arranged in rows and columns. It's also flexible enough to support formulas, charts, graphs, and a plethora of formatting features to assist with data manipulation and visualization. The .xls format was a common go-to in sectors such as business and finance, or any field that necessitated data analysis and presentation. However, the advent of the more sophisticated .xlsx format has largely overshadowed its use. |
| Technical details | 🔵 Diving into the technical details, the .xls format, the golden standard for Microsoft Excel versions prior to 2007, is capable of storing a range of spreadsheet elements, including worksheets, formulas, and macros. As a proprietary binary format birthed by Microsoft, its undocumented internal architecture has posed a significant challenge to compatibility with third-party software. The format is comprised of binary records that contain data, formatting, and embedded objects, offering the possibility of multiple worksheets, a variety of functions, and inter-sheet referencing. .xls files also have the capacity to include Visual Basic for Applications (VBA) macros, opening up avenues for automation and complex calculations. Despite the existence of alternatives like OpenOffice Calc, and options to convert between .xls and other formats such as .xlsx, the .xls format continues to hold its ground, largely due to its compatibility with older Excel versions and legacy systems. However, it's important to note that the newer .xlsx format, which made its debut in Office 2007 and harnesses XML and ZIP technologies, brings to the table improved efficiency and security features. Despite the potential security risks associated with macros, the .xls format continues to be widely used. |
