I want to make a column (lets say column A) that you can only enter text into it, and reject all numbers.

I have tried "custom" and "=istext()" for the formula... other options don't seem to work

for example: 2 --> reject hello2 --> accept 12 --> reject

one2one --> accept

Try selecting ColumnA and for validation this formula:

  • nope, but this works =arrayformula(istext(a1:a1000)) ... thanks for the hint

The data validation formula =istext(A1) works for me
