Hello @Austine ,

Try this regex pattern- /^[A-Z0-9 !@#$%&*_-]+$/

Sample code :

// String to validate
var input = "";

// Define the regex pattern: only uppercase letters, numbers, spaces, and special characters
var pattern = /^[A-Z0-9 !@#$%&*_-]+$/;

// Test the string against the pattern
var isValid = pattern.test(input);

// Display the result
if (isValid) {
    gs.info("Valid input!");
} else {
    gs.info("Invalid input!");
}

Hi @Austine ,

Hope this Answer is useful to your requirement . 

To create a regex validation in ServiceNow that accommodates only uppercase letters, numbers, spaces, and specific special characters (!@#$%&*_-,), you can use the following regex pattern:

Explanation of the Regex:

• ^ : Asserts the start of the string.
• [A-Z0-9 !@#$%&*_,-] : Defines a character class that allows:
  • A-Z : Uppercase letters.
  • 0-9 : Digits.
  • A space.
  • The special characters !@#$%&*_-,.
• * : Allows for zero or more occurrences of the characters in the class.
• $ : Asserts the end of the string.

Implementation in ServiceNow:

1. Go to the field you want to validate.
2. In the Dictionary entry of the field, find the Validation or Business Rules section.
3. Enter the regex pattern above in the validation condition.

script if you're using a Business Rule or Script Include:

var inputString = current.email; 
var regex = /^[A-Z0-9 !@#$%&*_,-]*$/;

if (!regex.test(inputString)) {
gs.addErrorMessage("Invalid input. Only uppercase letters, numbers, spaces, and special characters (!@#$%&*_,-) are allowed.");
current.setAbortAction(true);
}

Thank you
