Bottom Line. While Excel (XLS and XLSX) file formats are better for storing more complex data, CSV files are supported by nearly all data upload interfaces.

As a general rule, if your file size is small (less than 5 MB), it's better to stick to XLSX/XLSM formats. Based on what I heard from people and read on many forums, a lot of people prefer to use XLSB as the file format when it comes to using Excel.

Why is my CSV file so big?

The reason might very likely be that there are empty rows that fill up space somehow. If you open the CSV, can you scroll all the way to the bottom with a lot of empty rows? Then that's the culprit, try delete the empty rows and save the file again.
