RegEx

RegEx tab let's you test your regular expressions. You can write your regex in the top pane and the expression to be tested in the lower pane.

If regex turns red, it mean it's malformed. If the expression to be tested turns red, it means it doesn't validate against the provided regular expression.

Example

^\d{1,5}$

Output

Matches: 0 12345 Doesn't match: 123456 abc
