How to download data extract as a .csv

I am trying to download my data extract as a .csv but it will only download as .csv.gz. I am unable to open an .gz files. Can someone tell me how to download the file as a .csv?

Thank you

The .gz file is a type of compressed file, similar to a .zip file. You will need to decompress the file before opening it. We recommend 7-Zip for Windows and either the built-in archive utility or The Unarchiver for Mac.
