yes, it is, but it need some tricks, if you are creating a record its very straigt forward.

just make sure the colum name in csv exactly match the database field name, and then upload the csv use Upload Data as CSV … but if you are trying to edit data.

you need to use data api call,

first, you need to read the csv file then for each cell you need to call the data API with the UNIQUE ID of the item and update the field.

Use bubble Manual how to do it: Data API requests | Bubble Docs

if you still stuck book a call i will walk you how to do it.
