Really useful tutorial, changing data types is an important step in the data cleaning process. Great work

Very helpful video, thanks! I just wonder if its possible to change just some of mye columns from character to integer? And also, it didn't change my columns from character to integer using this code. I think it is because the numbers are "23, 3" instead of "23.3". Should I change all the commas to point's in all cells? How do I do that? Thanks again.
