I said it before: we need Copilot flash fill. Infer what the user wants the output to be from patterns and labels, so they can enter a few examples and then “extend” and automatically do the equivalent of a complex formula. e.g.<p><pre><code> Formal | Informal
Lane, Thomas | Tommy Lane
Brooks, Sarah | Sarah Brooks
Yun, Christopher |
Doe, Kaitlyn |
Styles, Chris |
…
</code></pre>
Automating something like this is extremely hard with an algorithm and extremely easy with ML. Even better, many people who use spreadsheets aren’t very familiar with coding and software, so they do things manually even in cases where the formula is simple.
