Uploading 200,000 (google sheet rows) into Google Maps

Im trying to create an app where i can see all of the information for every home in a residential area based on the county.

So, I downloaded CSV files from the local county of all the information, However i can only upload around 1,000 to fit on my google map.

Can anyone help with this? Also can anyone help create custom windows etc i will pay. Im not a dev, im just a very determined entrepreneur.

That may have to do with API limits
