.svg to .ai

Hi. I'm trying to convert a .svg file to a .ai file so I can open it in AE.

Currently I click File > Save As > Save on your computer. I then make sure the file type is .ai and hit export. However, when I export, it says 'Illustrator tried but could not export the file.

The .svg file is of a graph that I made in Google Sheets.

I am following this tutorial.
