Your project has exceeded the logical size quota

Good Day,

I am having an issue accessing my db .I accidently went over the hobby plan and I seem to have no way of reversing this action as I am seeing the following message when I tried to delete a table or truncate data:

[XX000] ERROR: Your project has exceeded the logical size quota. Upgrade your plan to increase limits.

IS there a way I can gain access to the tables in order to transfer the data locally or to another provider? I am learning at this point and do not feel it necessary to upgrade the plan until I have a use case for it.

Thanks for the help in advance!
