Use Power Query to Change Text in Cells or Columns

Change text in Power Query is easy to do. Some transformations include change the case (i.e., upper vs. lower), adding or removing spaces and changing special characters. All this can be done with in the Ribbon tools to the text in the cells. However if you wanted to change all the headers cells to make the text change case or remove characters, that would involved going into the M code. It's not hard, but it's worth it if you have a lot of column headers to change.
