Excel file formats

Excel is a popular spreadsheet software developed by Microsoft. It allows users to create, edit, and analyze data in a tabular format. Excel files can be saved in different file formats, each serving a specific purpose. Here are the main extensions used for Excel worksheets:

Excel Workbook (.xlsx)

The .xlsx extension is the standard file format for Excel workbooks. It stores data, charts, and other elements in a structured manner. This format is widely used for sharing and collaborating on Excel files.

Excel Macro-Enabled Workbook (.xlsm)

The .xlsm extension is used for Excel workbooks that contain macros – small programs that automate tasks in Excel. This format allows users to run macros within the workbook, making it ideal for automating repetitive tasks.

Excel Binary Workbook (.xlsb)

The .xlsb extension is a binary file format that stores Excel data in a more compact and efficient manner compared to the .xlsx format. This format is useful for large Excel files that require faster processing speeds.

Template (.xltx)

The .xltx extension is used for Excel templates – pre-designed worksheets that serve as a starting point for creating new Excel files. Templates help users save time and ensure consistency in formatting and layout.

Understanding the different extensions for Excel files can help users choose the appropriate format for their specific needs, whether it's sharing data, automating tasks, optimizing file size, or creating standardized templates.
