Convert XLSB to _XLS

Understanding xlsb and xls file formats

XLSB (Excel Binary Workbook) is a Microsoft Excel file format that stores spreadsheet data in a binary format, making it faster to open and save large files compared to the standard XML-based formats. XLS is the older Excel file format, based on the proprietary binary format used by Excel 97-2003. While XLSB is more efficient for large datasets, XLS is widely compatible with older versions of Excel and other spreadsheet software.

Why convert xlsb to xls?

Converting XLSB to XLS is useful when you need to share files with users who have older versions of Excel or other spreadsheet programs that do not support the XLSB format. The XLS format ensures broader compatibility, though it may not support some newer Excel features.

How to convert xlsb to xls

The most reliable way to convert an XLSB file to XLS is by using Microsoft Excel itself. Here’s how you can do it:

1. Open your XLSB file in Microsoft Excel.
2. Go to File → Save As.
3. Choose the location where you want to save the file.
4. In the Save as type dropdown menu, select Excel 97-2003 Workbook (*.xls).
5. Click Save.

This process will create a new XLS file from your original XLSB file.
