Data Validation for Alphanumeric and Hyphens (dashes) for a column

[vakar4uk]

Hello,

I'm trying to add Data Validation to 50 cells in a column that will only accept:

1. Alphanumeric
2. Hyphens (dashes)

No restrictions for length.
I did find some examples, but they are all for a single cell. If I try to change it to a range it breaks and won't let me save.
I tried this: =ISNUMBER(SUMPRODUCT(SEARCH(MID(A1,ROW(INDIRECT("1:"&LEN(A1))),1),"0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ-")))
Which works for cell A1. However, if I change A1 to anything else - it won't let me even save the formula. And I need a range instead - O2:O50.
Here is how I am trying to do it:

1. Select a range of cells I need apply validation to, which O2:O50
2. Click on Data Validation
3. Select Custom Data validation and enter a formula above into the Formula entry.

Thank you so much in advance!

You just need the formula to reference O2.
You can also simplify it slightly like

=ISNUMBER(SUMPRODUCT(SEARCH(MID(UPPER(O2),SEQUENCE(,LEN(O2)),1),"0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ-")))

=ISNUMBER(SUMPRODUCT(SEARCH(MID(UPPER(O2),SEQUENCE(,LEN(O2)),1),"0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ-")))

Thank you!

And how would it apply it to the range O2:50? Or do you mean to select the range, then in the data validation enter that formula?

Thanks!

That's right.

That's right.

This works perfectly, thank you so much!

Dear friend,
I came across this thread and found useful...but unfortunately I'm unable to use it...

I'm getting this error message.

Moreover I'm looking for character length restriction to 16. Only alphanumeric entries that contain both alphabets and numbers in the sequence AAAAXXXXXXXXXXXX where AAAA - alphabets (UPPERCASE) & XXXXXXXXXXXX - numbers (0-9).
Any help will be appreciated.
