Can you easily create the number list in Excel? If so then you can automate by saving as a .txt file and either place that directly or use DataMerge.
I feel like it would be much easier in excel. I've never used data merge though? Would it automatically set each cell to be on it's on page, centered and a font of my chosing?
With Data Merge you set up a template document containing field placeholders, and format it to your liking. The merge proces duplicates wahtever you set up. You can do either a single record (row in Excel) or as many as will fit on a page. Read about it in the Help files -- teh expalanation there is very good.
You can do something very simliar by adding a text frame to a master page and setting a paragraphh style that suits you for formatting, along with a Keep Option to start on next page. Then just place the saved text file using File > Place.... holding down the shift key to autoflow the entire list (click the loaded text cursor in the area of the empty master text frame).
Both of these seem very confusing to me. I'm fairly new to indesign but I will try it out.
I was able to create all the labels on excel and save them as a txt file. I will touch base with you soon. The second version seems easiest.
