Regular Expression Algorithm

Question

Something like this in my head: I put one or more lines, and the algorithm shows me the corresponding regular expression.

Is there any “easy” way to do this, or is something like that already exist?

Edit: Yes, I'm trying to find a way to generate a regular expression.

Edit: Regulases are not what I'm looking for. The usual use of the code I want is to find the correct regular expression, such as articlenumbers.
Example:

• I set 123456, the regex should be \ d {6}
• I put in nb-123456, the regex should be \ w {2} - \ d {6}
