What is Z file format?

The Z file format is a popular archive file format used to compress and store multiple files and directories into a single file. It was originally developed for the Unix operating system, but is now also supported by many other platforms, including Windows, macOS, and Linux. Z files usually use the .z or .zip file extension, and are created using the open source compression tool gzip. The Z file format is an effective way of reducing file size and storage space. It also allows users to keep multiple files and folders together in a single file. This makes it easier to transport and share data, as the entire set of files can be easily emailed or moved to another machine. Unlike other archive file formats, Z files are not self-extracting, meaning they must be manually extracted by the user. To open and extract the contents of a Z file, users must either rely on third-party software, or use the command-line interface. Overall, the Z file format is a useful way of compressing and archiving multiple files and folders into a single, smaller file. It is widely supported by many platforms, but requires users to manually extract the contents.

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.
