Turning Raw data into TypeORM Entity

I have data that I am sending to my NodeJs server that is in the standard SQL format with the default SQL column names etc.

I want to take these raw entities and reinsert them into the db. It seems like I can't insert them straight up without converting them into entities, or preparing a raw SQL statement.

I want to turn these values into TypeORM entities automatically without having to write transform functions.

Is there a good way to accomplish this in TypeORM?
