Convert _XLS to XLSB

Understanding XLS and XLSB file formats

The XLS file format is a spreadsheet format created by Microsoft Excel. It is part of the Microsoft Office suite and is used to store data in a tabular form, including formulas, charts, and macros. XLS files are based on the Binary Interchange File Format (BIFF) and are widely used for data analysis and reporting.

The XLSB file format, on the other hand, is a binary spreadsheet format also used by Microsoft Excel. Unlike the XML-based XLSX format, XLSB files store data in a binary format, which can result in smaller file sizes and faster performance when opening and saving files. This makes XLSB an excellent choice for large spreadsheets or when performance is a priority.

How to convert XLS to XLSB

Converting an XLS file to an XLSB file can be done easily using Microsoft Excel. Here’s how you can do it:

1. Open the XLS file in Microsoft Excel.
2. Click on File in the menu.
3. Select Save As from the dropdown menu.
4. Choose the location where you want to save the file.
5. In the Save as type dropdown, select Excel Binary Workbook (*.xlsb).
6. Click Save to complete the conversion.

Best software for XLS to XLSB conversion

The best software for converting XLS to XLSB is Microsoft Excel itself. As the native application for both file formats, Excel ensures that all data, formulas, and formatting are preserved during the conversion process. Additionally, Excel provides a user-friendly interface and supports batch conversion for multiple files.

For those who do not have access to Microsoft Excel, online converters such as Zamzar or Convertio can also perform the conversion, though they may not support all features of the Excel file.
