I want the EURO format to be accepted only in the following forms.

Three digits with "." Be segregated.

^(0|(([1-9]{1}|[1-9]{1}[0-9]{1}|[1-9]{1}[0-9]{2}){1}(\ [0-9]{3}){0,})),(([0-9]{2})|\-\-)([\ ]{1})(€|EUR|EURO){1}$

Solution

  • You can try

    ^(?!0\d)\d{1,3}(?:\.\d{3})*,\d{2}$
    • ^ start of the string
    • (?!0\d) negative lookahead, make sure there's no leading 0s like 01,25, remove it if it is allowed
    • \d{1,3} 1 to 3 digits
    • (?:\.\d{3})* followed by any occurances of texts like .123
    • ,\d{2} followed by 2 decimal digits, mandatory. If you want it to be optional, replace it with (?:,\d{2})?
    • $ end of the string
