Here are some common questions and answers about xlsb file conversions ask by our users on RunConvert.com.
Frequently Asked Questions
Q: Can I convert a spreadsheet with VBA code?
A: VBA doesn’t transfer to other formats. You’ll need to keep it in XLSM if the code matters.
Q: Why use spreadsheet conversion at all?
A: Sometimes you need a lighter file, better compatibility, or just a shareable version. Conversion keeps your data flexible and accessible.
Q: Is RunConvert faster than desktop apps?

Q: Does spreadsheet conversion change my data?

What is XLSB (Excel Binary Workbook)?
XLSB (Excel Binary Workbook) is a file format used by Microsoft Excel for storing spreadsheet data in a binary format. Unlike the more common XLSX format, which is XML-based, XLSB stores data in a binary structure, making it faster to open and save for large workbooks.
XLSB files are typically used for large and complex Excel workbooks that require faster processing and lower file sizes.
How to open XLSB?
XLSB files can be opened using Microsoft Excel (Excel 2007 and later). You can simply double-click the file to open it, or use the 'Open' option in Excel's file menu.
XLSB files are not compatible with some other spreadsheet programs like Google Sheets. However, they can be opened in Excel, which is the recommended program.
XLSB is Developed by: Microsoft
XLSB was Released on: 2007
