How to validate that the "street" should contain only upper case. Though it can contain number and spaces

For example:
should accept below

• 1 ABC ST
• 1 ABCST
• ABCST
• ABCST 1

should not accept below

• 1 aBC ST
• 1 ABCSt
• ABcST
• abcst 1

>Solution :

You can use a regular expression to constrain a string. In your case it would be something like this.

{
   "type": "string",
   "pattern": "^[ A-Z0-9]+$"
}

You can make the regular expression more advanced to not allow leading and trailing space etc.
