Convert XLSM to XLSB

Understanding XLSM and XLSB file formats

XLSM is a file format used by Microsoft Excel that supports macros. It is part of the Office Open XML format and is used for spreadsheets that contain VBA (Visual Basic for Applications) code. This format is ideal for users who need to automate repetitive tasks within Excel.

XLSB is another Excel file format, known as the Excel Binary Workbook. It stores data in a binary format rather than the XML format used by XLSM. This makes XLSB files faster to open and save, and they often result in smaller file sizes. XLSB is suitable for large spreadsheets or when performance is a priority.

How to convert XLSM to XLSB

Converting an XLSM file to an XLSB file can be done using Microsoft Excel itself or through specialized file conversion software. Here’s how you can do it using Excel:

• Open the XLSM file in Microsoft Excel.
• Click on File in the menu.
• Select Save As.
• Choose the location where you want to save the file.
• In the Save as type dropdown menu, select Excel Binary Workbook (*.xlsb).
• Click Save to complete the conversion.
