xlsm

Extension	.xlsm
Category	🔵 documents
Description	🔵 The XLSM format is a file extension used in Microsoft Excel to indicate a spreadsheet that contains macros written in the Visual Basic for Applications (VBA) programming language. It is an advancement from the traditional XLSX format, which does not include macros. 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 routines, helping users streamline workflows and boost productivity. XLSM files are commonly used in business, finance, and data analysis applications that require automation and customization.
Technical details	🔵 XLSM files are based on the Open XML format, which is a zipped, XML-based file format developed by Microsoft for representing spreadsheets, charts, presentations, and word processing documents. The main components of an XLSM file are XML files for workbook structure, styles, themes, and shared strings stored within the compressed archive. These XML files describe the content and formatting of the spreadsheet. XLSM files support macros written in VBA (Visual Basic for Applications) and can be opened and edited in Microsoft Excel, as well as other spreadsheet software that supports the Open XML format. The ".xlsm" file extension is used to differentiate macro-enabled Excel workbooks from standard Excel workbooks, which typically have the ".xlsx" extension, helping users and applications identify files that contain macros.

Microsoft Excel Binary File Format

Description	🔵 The .xls format is the default file format for spreadsheets created in Microsoft Excel, particularly in versions before Excel 2007. This binary file format can store data in cells organized in rows and columns, and it supports formulas, charts, graphs, and various formatting features to manipulate and visualize data. The .xls format was commonly used in business, finance, and any field requiring data analysis and presentation, but has since been largely replaced by the more advanced .xlsx format.
Technical details	🔵 The `.xls` format, primarily used for Microsoft Excel versions before 2007, stores spreadsheet elements such as worksheets, formulas, and macros. Being a proprietary binary format created by Microsoft, its undocumented internal structure has made compatibility with third-party software quite challenging. This format consists of binary records that contain data, formatting, and embedded objects, allowing for multiple worksheets, various functions, and inter-sheet referencing. `.xls` files can also include Visual Basic for Applications (VBA) macros, which enable automation and complex calculations. While supported in applications like OpenOffice Calc, there are options available to convert between `.xls` and other formats such as `.xlsx`. Despite security concerns related to macros, `.xls` is still commonly used due to its compatibility with older Excel versions and legacy systems. However, the newer `.xlsx` format, introduced in Office 2007 and utilizing XML and ZIP technologies, offers improved efficiency and security features.
