 ### Import xlsx files with polars and calamine
 Power of Polars Library in data manipulation and analysis.
+It uses the polars library to read the Excel data into a DataFrame by passing the bytes to the `pl.read_excel()` function -
 https://docs.pola.rs/py-polars/html/reference/api/polars.read_excel.html
+In `pl.read_excel()` “calamine” engine can be used for reading all major types of Excel Workbook (.xlsx, .xlsb, .xls) and is dramatically faster than the other options, using the fastexcel module to bind calamine.
