Turn Any CSV into an Executive Report with Python and AI
# Moving Beyond Analysis By Hand Every analyst has done this by hand. A CSV lands in your inbox, someone asks "so how did we do," and you spend an afternoon cleaning columns, building a few charts, and typing up what they mean. In this walkthrough, we build a small pipeline in Python that takes a raw sales CSV, cleans it, runs the numbers, draws the charts, and asks an AI to draft the insights.

A CSV lands in your inbox, someone asks "so how did we do," and you spend an afternoon cleaning columns, building a few charts, and typing up what they mean. We can automate most of that. In this walkthrough, we build a small pipeline in Python that takes a raw sales CSV, cleans it, runs the numbers, draws the charts, and asks an AI to draft the insights. The AI here is Claude Opus 4.8. The model writes the first draft of the narrative in seconds. We still decide what is true. Before any of that, the report needs a question. Ours is: how much revenue did we keep over these five weeks, and where did the rest go? Every step below answers a piece of it. Cleaning decides which rows count as money.
