The most common file type is .xlsx which is available to both Windows and Mac users. It has many advantages including being able to store larger datasets than its predecessor, the .xls file type. However, it also has some disadvantages such as not being able to use features like macros or conditional formatting on older versions of MS Excel or on Macs.
