im making a dnd tool, its a html file,  that uses  fetch('monsters.csv') javascript to load all the stats of the monsters. I wanted it to be serperate so that I can add to it as i GO. but right now it works on my PC but when i upload index.html and monsters.csv the list from my csv does not load. is there a reason i cannot fetch from a csv?

NM i uploaded it as a zip and it works now.
