Regex for Non Alphabets, Non Numbers and special characters

Hi,
Can someone help me to build the regex to filter out non alphabets and non numbers as well special characters?

So here is the rule : According to the rule, it means you can have numbers and/or alphabets. You can't have anything else. Nulls can be ignored here

1234 - Keep

ab123 - keep

abcd - keep

anything which doesn't have these combination should be filtered out using the regex

@gotu
use the formula

REGEX_Match([YourField], "^[a-zA-Z0-9]+$")

mark done if solved.

Hi,

Sorry but this doesn't work

I'm expecting the results as shown but this regex is giving something else.

@gotu
find workflow attached.

In a filter tool, use:

REGEX_Match([fieldname],"\w+")

Unfortunately neither worked for me.

One thing i wanted to add is that we can have data as B12 BT5 or 123 456 so there is space allowed when its numbers, alphabets or alphanumeric.

@gotu
update the formula to this
REGEX_Match([fiedl], "^[a-zA-Z0-9 ]+$")

This works for me.

If white space is also allowed, use REGEX_Match([Field],"[\w ]+")

If you still aren't getting the results you need, it would help to share some sample data.
