Need help with Regex Apply cleanup rule

[gabriel_gomez]

Hello I am trying to create a regular expression that removes commas.

Example 583,100

should be 583100

I am creating the following expression but it divides the result

([0-9][^,\s]*+)

The idea is that all the value is output in a single complete line 583100 without the comma

I was unable to concatenate the two groups via regex 😞 maybe someone else will have better luck.

I believe this is not solvable using one capture group.  You could do that using two capture groups, something like:

(\d+)[,]?(\d?+)

and then use the value of both capture groups concatenated.
