    It works with all versions of Windows. We don't support Mac OS X or Linux.

  6. I really want to use DataNitro on a Mac.

  9. My Python functions aren't appearing in Excel.

    Make sure that user-defined functions are turned on in "Settings". If they are, check that you're importing your functions in a file called "". They won't appear as functions inside Excel cells if you use a different filename.
