In my SharePoint list, I need a text column [ID] to validate as 5 numbers, a period, and then 3 numbers. Example: "15202.123" and I need help. :-)

Thank you!

Try this:


First it validates if it's a 9 character string or not, then checks if the 6th character is a dot (.), then it validates the first 5 and last 3 characters.

Of course, it might be possible to write in an easier way.

Let me know if this helps.

  • UBK! Thank you!!! This is exactly what I was looking for. I REALLY appreciate your time and brilliance. Cheers!
