Regex to filter alphanumeric combinations

[dougejm]

Hi,

I am looking to filter out items not matching the requirements. I'm looking to keep items containing letters, numbers and special characters, it can be different combinations and I am struggling to get on regex code to match them all (or a simpler way to do it). If any help, each item will always be 3 characters or more.

Example what to keep/filter out:

abc123 (Letters and Numbers in any order = KEEP)

123456 (All numbers = KEEP)

abc-123 (Letters, special character, number in any order, length and any special character = KEEP)

abcdef (All Letters = OUT)

abc-efd (All letters and special characters in any order = OUT)

Hope this makes sense and thank you in advance

@dougejm I'm a little confused by the logic here. In your explanation you say 'filter out items containing letters, numbers and special characters', but in example 3, this is exactly that and you say it should be kept? From your examples, it looks like you want to filter anything where there aren't any numbers present - is that right? If that's the case then you can use a filter like so which just checks whether there's 1 (or more) occurrence of a digit:

REGEX_CountMatches([Input], '\d') > 0

Hi yes, apologies I'm using different/wrong wording. In the text I meant filter out as keep as in filtering through the filter and be kept. Sorry that is very confusing of me. Trying to find a way to change the text/question but not able to find it.

The example is the right way what to keep/not to keep.

No problem @dougejm. I made an edit to my post which might've been as you were replying - would that filter handle your request or are some records still getting through that you need removing?

Worked like a charm, thank you! I have marked it as the solution
