Artificial Sweeteners Are Not Harmful For Gut Microbiota, They Are Even Prebiotics | Science 2.0
Almost immediately, trial lawyers at groups like Center for Science in the Public Interest began claiming these artificial sweeteners were harmful to humans. When their war on all saccharin, the first popular noncaloric sweetener, failed, those groups began to focus on diet soda. They dropped scary-sounding chemical names like formaldehyde and since most of the public are not aware that formaldehyde is also produced naturally, and that to get enough formaldehyde in a diet soda to have an impact requires ingesting 7,000 cans per day, they had some success. Even now a Goop or Whole Foods shopper will casually state that diet soda is "bad" for you.

A recent review of claims that diet soda are bad for gut microbiota show it isn't so. Instead, low‑calorie sweeteners seem to have beneficial effects since they act as prebiotics, which are said to be foods that good gut bacteria consume.
The review covered natural sweeteners (1), synthetic sweeteners (2), and sugar alcohols and polyol sweeteners (3) to examine their effects on the composition of microbiota in the human gut. Obviously you should see the paper to find details on everything they reviewed.
There was no harm. There were some changes with saccharin and sucralose but there are also changes if you drink water, black coffee, or coffee with honey. They aren't negative effects.
