When an Excel worksheet needs to handle very large datasets, converting to the Xlsb format not only results in a smaller file size but also offers faster read/write speeds, allowing you to store and manipulate millions of rows of data. When running complex macro code, the Xlsb format provides more efficient support for VBA macros. Also, when frequently working with data, it delivers better performance for opening and saving files. Converting Excel spreadsheet files to the Xlsb format is suitable for scenarios involving processing big data, running complex macros, improving performance, or enhancing data security.
1. Use Cases
If you have files of multiple Excel worksheet types such as Xls and Xlsx that need to process extremely large data content or run more complex VBA macro code, you can batch convert them all to Xlsb format to significantly improve file operation performance and data processing efficiency.
