How to add a note or comment into a formula in Google Sheets?

Question

Microsoft Excel

Microsoft Excel has this feature where one can add a note into a formula with the N() function. It looks like this:

Google Sheets

Does Google Sheets have a similar feature to embed notes and comments into a formula?

I'm not talking about the concatenate function which is something different than what I mean.

I'm also not talking about the "Insert comment" feature which is also different.

Answer 1

You can have the same functionality in sheets as well.

&T(N("comment"))

OR

=IFERROR(A1/A2,"") &T(N("comment"))

OR

=YourFormula+N("comment")

(This last one works when the formula gives numeric results)

Answer 2

I found that none of the solutions I found for this question worked for my specific situation, so I did some research and testing and found my own solution.

I want to add multiple comments to a formula in a single Google Sheets cell. I found I could use this function to do it:

code("Insert comment here")*0

Here's a usage example:

There are likely other ways to achieve the same thing (converting a string to a zero number so it will have no effect on the formula), but I stopped at the first one I found because it's all I needed.
