    Beginner AI Dataset Generator using OpenAI + LangChain

    Generates realistic sample datasets from a topic using OpenAI via LangChain. Automates JSON structuring, flattening, column inference, and data pivoting for clean exports.

It leverages OpenAI through LangChain nodes to first generate structured JSON data with 5 columns and 3-5 values each, then flattens it into a text blob, infers meaningful column names via a second AI call, and automatically pivots, splits, merges, and renames columns for a polished output ready for CSV export or further processing. Benefits include rapid prototyping of datasets without manual data entry, ide
