changing class of column to numeric creates random blue hyperlinks to nowhere

I recently started coding and I am trying to convert column classes to numeric. I have imported a simple excel file. Whatever method I use, some numbers are changed to blue hyperlinks that can not be used as numbers anymore. When I press them they simply lead to google chrome. does anyone know what's going on? I added a printscreen as example. Thanks!! linkss|690x261


Welcome to the community!

Is it always the same numbers that end up being a link? And if you look at them in the excel file, are they formatted differently?

It's good you added a screenshot, but the best way of stating you problem is by providing us a minimal reprocudible example where you provide a minimal (dummy) dataset and code that can recreate the issue. Once we have that, we can go from there. For help on creating a Reprex, see this guide:

Good luck!
