People searching for something is reflective of what people search for, in some cases for products it's reflective of popularity but, I would argue in this case there's a good chance people are searching for Excel more for tips/troubleshooting/how to, than purchase intention.

If you look at a range of wide range business functions, opening and editing text documents is more prevalent than using spreadsheets.

I asked you how you were "certain" what you were saying was true.

You haven't provided anything in answer to that, and instead just criticize something that shows what you claimed wasn't the case.

So, please, go ahead and provide data showing what you're claiming is in fact the case.

Google trends indicate that Excel is harder to use without a manual than word, nothing else.

I don’t think that’s a good indicator of popularity. Most people are going to be searching for “how to do X” with the product name to refine results. Excel is more complex, so likely has more of those sorts of search queries.

Thus, why I asked the person above how they are "certain" of a thing.

Seems like a double standard. Person above makes a claim with nothing to back it, I counter the claim with an actual cite. Everyone jumps on me instead of them, for, providing anything at all?
