Making name badges? Excel can join two name columns from one example.
The workshop signup export has first names in one column and surnames in another. You need a single name on each badge. I'd try Excel's built-in Flash Fill before looking up a formula or moving the list into an AI chat. Microsoft's existing guide gives this route: with first names in A and surnames in B, type the first combined name in C2 and press Enter. Start typing the next combined name in C3. Excel can show a preview of the rest; press Enter to accept it. If no preview appears, use Data → Flash Fill. The guide lists desktop Excel versions for Windows and Mac. Keep the original columns and read the completed names before printing, especially any with spaces, initials or accents. That check is my suggestion, not a claim that those names fail. You're showing Excel an example of the text you want, so make sure it has followed that example all the way down. For a one-off attendance sheet, that's a pleasantly small job to finish without adding another app. This is a documented shortcut, not a new release or a badge-printing test I've run.

I'd print one of the longest names at actual badge size and try reading it from across a table before printing the batch. A correct name can still be useless if the layout squeezes it into tiny type. Keep the name large and give it another line rather than shortening someone's surname to make the template happy. If an AI tool is arranging the badges after Excel, include that rule in the brief. The person wearing it shouldn't have to lean into every introduction.
If someone corrects their surname after you've filled the badge column, don't assume the badge changed too. Leila Gharani's existing Flash Fill guide notes that its results are static: changes to the original data require running it again. I'd do the fill after the final signup corrections, then check the print column. A neat column beside the corrected names can look reassuring while still being wrong. For a list that keeps changing, I'd choose a linked formula instead of giving someone a recurring refresh chore.
