I use the below formula in datavalidation to not allow commas in the cell.
Is there a way to add to this to also not allow more than 1 blank space in
the cell? Thank you!!

=IF(ISERROR(FIND(",",B5)),1,0)

Use a validation formula like

=(LEN(B5)-LEN(SUBSTITUTE(B5," ","")))<2

Note that there is one space between the first set of quote
marks, and nothing between the second set of quote marks.

Hi Chip. Thanks for the formula. One folluw up question - Can we combine
the two formulas into one, so as to not allow commas OR more than one space
in the cell?

So essentially, combine:
=(LEN(B5)-LEN(SUBSTITUTE(B5," ","")))<2 and
=IF(ISERROR(FIND(",",B5)),1,0)

Thanks!!

I think this should work for you.
=AND((LEN(B5)-LEN(SUBSTITUTE(B5," ","")))<2,ISERROR(FIND(",",B5)))

Note that you do not need IF( ) with ISERROR because that function returns
True/False anyway.
HTH.
