How to Change Language in Looker Studio / Data Studio in 2026

Are you also here to change language in Looker Studio? Changing language of the report and widgets in Google Data Studio can be terribly frustrating; there are plenty of guides out there from when it was still called “Looker Studio”, but none seems to work.

And yet, the simplest thing to make it work is something every guide falls to specify. Here’s how to change language of the actual data of your Google Data Studio reports.

TL;DR

  • Your Google Data Studio panel is linked to your own Google Account.
  • You need to change the Language of your Google Account.
  • Once done, you need to log out of the account and log back in again.
  • Then, re-import your data sources, and you will have successfully changed the language of the report.

Changing the language in Looker Studio / Data Studio

All the guides and tutorials you’ve read so far agree on one thing, and that’s correct: you can’t control the language as a parameter in data studio; the platform UI is based on your Google account’s language. Thus, in order to change the language of the UI and of your data, you need indeed to hover to the top right of your screen, select the avatar of your account, and go to “manage account”.

Why changing the language alone doesn’t reflect on your reports?

If you’ve changed the language and still your reports look the same, even after re-importing the data, that’s because you have failed to do one thing: logging out of your Google Account to force a hard refresh. You see, Google stores your preference in a way that until you log out, services might still be hooked to your previous choices.

So, simply log-out of all accounts, and re-log in again.

Last step to effectively change the language of reports in Google Data Studio

Now, you will notice that the Data Studio UI reflects the changes. And yet, your data still speaks the previous language; that’s because you need to re-import it. Actually, you could also just refresh fields in most cases, but that depends on your connector.

  • Head over to data sources
  • Select your desired data source
  • Refresh fields or re-connect
