Sorry - should have been clearer - I have used the original VB code "Sub parse_data()" - Regards Tom C.

@Gandalf-3 That sounds like a good idea. We can add a conditional in the current line 32 (Sheets.Add) that truncates the string if it gets beyond 31 characters, or something similar. Have you written a snippet? I could update the changes here and mention you as a contributor here if you're happy with that.

Since this is a gist and is not designed for collaboration, I could add it to https://github.com/martinctc/Excel-VBA and we can collaborate properly on there as well.

Hi, not a programmer but I found this script via this tutorial: https://www.excelhow.net/split-data-into-multiple-worksheets-based-on-column.html and after testing, it is going to work AMAZINGLY for manipulating/automating our massive circulation list for our school library (which "dumps" from the database as a single-worksheet csv, mass-of-data nightmare), EXCEPT that it's returning blank worksheets for any strings that contain special characters.

Books04-19-21-WithMacros-SAMPLEONLY
(Above screenshot is of a small sample dataset with private info removed- the main screen shows the worksheet I started with, with the tabs at the bottom & in the worksheet list having been created by the script. Note that blank sheets start at 41 only because of previous tests on same file.)

Is there a way to change this VBA code so that it works with special characters? Or will we have to find & replace each special character before running the macro each time? (The initial data export will always have special characters, unfortunately.)

Any advice would be truly GREATLY appreciated and thank you also for the starting script!
