I have a raw CSV export of customer-level transactions from our retail platform and I need clear, data-driven insight into which products are really driving revenue. The goal is simple: surface product-level sales trends so I can see which SKUs consistently outperform and which ones lag behind, all viewed through the lens of revenue generated rather than just unit counts. You’re free to structure the workflow as you see fit, but I expect the core analysis to happen in Python, leveraging pandas and NumPy for data wrangling and aggregation. I’ll supply the dataset along with a brief data dictionary; you return a well-commented Jupyter notebook (or .py script) that: • Cleans and normalises the raw data • Calculates revenue by product over selectable time windows &b...
I have more than twenty-one separate census workbooks that need to become one clean, analysis-ready master table.

I want to turn my raw market-trends data into clear, action-ready insights with the help of a custom AI assistant. The core requirement is data analysis: the system should ingest whatever format I send—usually CSV and Excel dumps, occasionally a direct database export—and automatically clean, analyse, and visualise the material so that I can spot patterns, outliers, and emerging opportunities at a glance. I expect the workflow to be fully automated once a file is dropped into a designated folder (or a table is updated). Behind the scenes you can rely on Python, pandas, scikit-learn, or similar tooling; as long as the final solution is reproducible and easy for me to extend, the choice of libraries is up to you. I’m comfortable running scripts locally, but a lightweight w...

I have a sizable dataset that first needs to be cleanly extracted and then thoroughly analyzed. Because the information comes from multiple sources, I will provide a mix of Excel/CSV tables, a small hosted database dump, and several raw text exports.
