This tool will help you download all of your search console data.
First you'll need to authorize so it can access you search console profiles.
Don't worry this all runs locally in the browser and we won't do anything with your data other than download it in the browser and give it straight back to you.
It all runs in your browser. We've tested up to a couple months of data on some reasonably large accounts.
But there probably is a point where it falls over because the browser can't handle it.
If you find your self doing this regularly / for multiple profiles / wanting to store it somewhere - Piped Out might be worth a look!
As we said earlier, your data won't go past your browser, but if you're feeling particularly privacy conscious you can always revoke our access in your Google Account admin. Instructions here.
Blog post here has more details on how it's built & any issues you might encounter.
