Questions and answers often contain links to Google sheets but miss the data in the question. Perfect example for both Q and A*:
Can we please emphasize (in comments) that sample data (numbers or formulas; actual vs. expected results; input vs. output) should be in the question (layout as code, most times), and that a link to a live sheet is welcome but not enough.
Many of those links will die because the OP deletes the sheet after (s)he got an answer.
What would be a good text to remind them to do so?
Please add sample data to your question (actual vs. expected or input vs. output). A link to a Google sheet is welcome too, but not enough.
