NL2DATA

Introduction

Have you ever wished you could just ask your data a question and instantly get the answer as a chart or a table?

That’s exactly what NL2DATA does.

NL2DATA is an AI-powered platform that turns plain English into SQL queries and live data visualizations. Whether you want to retrieve raw data or generate dashboards, you can just type a simple prompt and no coding needed. It connects directly to your PostgreSQL database, translates your request into optimized SQL, fetches the data, and presents it in the most relevant form, either as a table or a chart.

In this blog, I’ll walk you through what NL2DATA offers and how you can start using it right away.

What is NL2DATA?

NL2DATA - Natural Language to Data is built to make data analysis easier and faster. Instead of writing complex SQL queries or spending hours designing dashboards, you can now just type what you need in natural language.
