TL;DR — Turn complex JSON blobs into SQL schema or SQL schema updates effortlessly with GPT-4.

Picture this: you’re working on a project or at your job, tasked with running an hourly job using Airflow or a simple cronjob to move data from a JSON API into SQL tables. You know the drill — designing the schema to match the source JSON can be a tedious, monotonous process.

With GPT-4, you can simply paste JSON output from any API into the model and ask it to generate a SQL schema tailored to your destination database. Say goodbye to manual schema design and hello to a new era of efficiency.

To illustrate just how powerful GPT-4 can be, let’s take a look at an example using Blockstream’s public Bitcoin API (https://blockstream.info/api/tx/406d0a5ac590ac7f2e96b7999eb40b5bdaaaf33da2204275d2e3671d3eda3754):
