Reporting on text/feedback/comments

Has anyone any experience reporting on text/feedback/comments etc.

We have conducted a course and asked delegates to complete an evaluation form with a range of metrics, some are short sentence answers i.e i attended this course because I wanted to increase my confidence with managing a team.

I am looking at a word cloud, but I wasn't sure if there were other options. Just want to make it visually easy to read.

Also with the word cloude, how can you combine 3 different columns into one word cloud? I can only add one at any any time.
