What is ICO file format?

ICO (or .ICO) is a file extension for an image file format used to store computer icon images. ICO files are used to store small images, such as icons for Windows programs and files, which can be in colour depths ranging from 1-bit to 32-bit. The ICO file format is an image file format that enables computer icons to be used in the Windows operating system and other Microsoft applications. ICO files can contain multiple images in various sizes and colours, and are usually used in programs such as web browsers, web sites and Windows. The ICO format makes it easy to quickly create and implement icons across multiple platforms, and they are extremely popular in the development world.

It is important to note that ICO files are not limited to Windows applications and can also be used to store favicons, website icons, and folder icons. Additionally, ICO files can be converted to other image file formats, such as GIF and PNG.

What is XLSM file format?

The XLSM file format is an extension of the XLSX file format used for Microsoft Excel workbooks. Similar to XLSX, it is based on the Open XML file format and is associated with the Excel application. The “M” in XLSM stands for “macro-enabled”, indicating that it supports the inclusion of macros.

XLSM files store spreadsheet data, including worksheets, formulas, charts, and other elements commonly found in Excel workbooks. Additionally, XLSM files allow the embedding of VBA (Visual Basic for Applications) macros within the workbook. Macros are scripts written in VBA that automate tasks, perform calculations, and interact with the spreadsheet data.

By including macros in XLSM files, users can create customized functions, automate repetitive tasks, and enhance the functionality of their Excel workbooks. Macros can be written to manipulate data, generate reports, perform complex calculations, or interact with other applications.

When opening an XLSM file, Excel prompts the user to enable or disable macros due to security concerns. Enabling macros allows the embedded VBA code to execute, while disabling macros prevents potential security risks associated with malicious code.

XLSM files provide advanced features and customization options for Excel users who require automation beyond the capabilities of the standard XLSX format. They are commonly used in business environments, financial modeling, data analysis, and other scenarios where complex calculations and automation are necessary.
