I am looking for an out-of-the-box solution (no code due to the lack of tools) for preventing the users from inputing list items with special characters. It would also be great if I could disallow names over a certain character length. Can somebody think of an easy solution to this problem?

  • Can you use InfoPath? You can use regular expressions with InfoPath. This link may help you.

Try this simple method using column validation.

On List Settings > Column > Column Validation, add this:


Source: How to validate the special character on SharePoint List Column


For those who's wondering how to include also apostrophes " and ' (or any other characters) in column validation just use CHAR(34) and CHAR(39) inside the FIND formula.



Please note there is a maximum of 20 items you can include in the above validation, which will NOT cover all the special characters.

But in windows certain ones cause problems for sure like /\<>|*:;"'?
