If you are using Google Data Studio as quite extensively as I do you maybe came across this rather annoying issue
Sometimes GET parameters get in the way of quality reporting and you would rather remove them all.
Of course, Facebook is the worst with his fbclick but can be useful for pagination, ecommerce filters and so on.

So now I’m using a calculated direct inside Google Data Studio, here is the formula to copy past for the savvy users:
For the other, here is the step by step:
Open your report and go to “Ressource” -> “Manage added sources”
and ‘ADD A FIELD’ on the top right
Name this new field something memorable and copy post the previous formula and you are good to go.
I hope you will find this useful
