Spreadsheets can be surprisingly useful in a text document. For example, I regularly need to grade programming assignments. I do this in.a structured text document, with sub-headings per student and category, where I take notes about their work, and assign points. So far, this could be easily done in markdown, or even plain text. But then I tally up the points, and convert them to a grade based on some simple equation in a table. My colleagues need to do this in a separate Excel sheet. I can do it right in my org document.
