I’m having a big problem trying to figure out what has gone wrong with my data in Challenge 22. I started well without any issues but all of a sudden everything I’m doing in Power query has become too slow that I might not be able to continue. It now takes several hours to perform a simple task. It appears the data has auto-grown on its own. Below is what I’m seeing in trying to load the data.
The data has grown to Gigabytes whilst performing simple transformations. Please I need help to figure out what has gone wrong.
