setting a Field on form to only allow text input

[Jon123]

Is there a way to setup the format on fields to only allow text inputs, no numbers wanted. I know I can do this at the table level but is some cases
numbers are ok. So I want to code it so I can control when numbers are ok and when there not.

Not with formatting, but you can investigate input masks
