What is MSG file format?

The MSG file format, developed by Microsoft, is designed to store email messages, contacts, appointments, and other messaging data. It is widely used across Microsoft products, including Outlook, Exchange, and Office 365. MSG files are structured to store data using MAPI properties and data types, allowing for various formats such as plain text, HTML, and RTF. Additionally, MSG files can store attachments like images, videos, documents, and other file types.

These files are typically generated when an email is sent or received, or when contacts or appointments are created or modified. Alongside messages, MSG files can also house other data, such as calendar events or tasks associated with an Outlook account. Furthermore, MSG files find application in various Microsoft applications, including Microsoft Teams, SharePoint, and Skype for Business.

One of the key advantages of MSG files is their reliability and security, making them a preferred choice for business purposes. They offer a robust and structured format for storing messaging data, ensuring its integrity and accessibility. This reliability, coupled with their compatibility across Microsoft products, contributes to their popularity in business environments.

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.
