About .xlsb Files
XLSB files are binary Excel spreadsheet files used to store complex data efficiently. They use the MIME type application/vnd.ms-excel.sheet.binary.macroenabled.12 and support macros for task automation.
Key use cases include:
- Efficient Data Storage: They handle large datasets faster than XML-based spreadsheets.
- Macro Support: They allow embedded VBA code for automating repetitive tasks.
- Enhanced Performance: Their binary format improves speed and reduces file size.
- Complex Calculations: They store formulas and functions in business and technical applications.
According to FilExt.com, XLSB files are popular in environments requiring fast performance and efficient storage of spreadsheet data.
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is the difference between XLSB and XLSX files?
The main difference is that XLSB stores data in a binary format, whereas XLSX uses an XML-based format. This makes XLSB files significantly smaller and faster to open, especially for large datasets, though XLSX is more compatible with third-party tools.
How do I open an XLSB file?
The best way to open an XLSB file is using Microsoft Excel (version 2007 or newer). You can also view them with alternatives like LibreOffice Calc or WPS Office, though complex macros might not run correctly in non-Microsoft software.
Are XLSB files safe to open?
You should be cautious because XLSB files support macros (VBA code), which can be used to hide malware. Only enable content or macros if you trust the source of the file; otherwise, open it in "Protected View."
Can I convert an XLSB file to a standard Excel file?
Yes, you can easily convert it using Microsoft Excel. Open the file, click File > Save As, and select "Excel Workbook (*.xlsx)" from the file type dropdown menu. Be aware that saving as XLSX will remove any macros.
Does Google Sheets support XLSB files?
Yes, Google Sheets allows you to upload and view .xlsb files. However, while the data and formulas usually convert well, any embedded VBA macros will not function within Google Sheets.
Why would I choose XLSB over XLSM?
If you have a macro-enabled workbook that is very large or slow to calculate, saving it as .xlsb often results in a smaller file size and faster load times compared to the XML-based .xlsm format.
What is the MIME type for XLSB files?
The specific MIME type for these binary sheets is application/vnd.ms-excel.sheet.binary.macroenabled.12. For a complete list of Excel-related types, you can visit mime-type.com.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
