Analyzing data with ChatGPT
Key Points
- Upload CSV/Excel or paste tables
- Request EDA + hypotheses, not just answers
- Ask for formulas, checks, and reusable outputs
Summary
ChatGPT helps engineers and analysts move from raw tables to actionable insights with minimal setup. You can upload a CSV/Excel, paste a table, or connect a supported data source, then ask for exploratory data analysis (EDA), hypotheses, visualizations, anomaly checks, forecasts, or slide-ready summaries. It’s most valuable early in exploration—finding anomalies, spotting conversion bottlenecks, and producing reuseable outputs (clean tables, KPI summaries, exec bullets) you can validate and act on.
Key Points
- Frame the decision up front: use a prompt like “I’m trying to decide ___, based on ___” so analysis stays focused on what “done” looks like.
- Provide data + context: include definitions, timeframe, key columns, and success metrics; upload files or connect apps when available.
- Ask for an approach not just an answer: request an EDA summary, ranked observations, and hypotheses to test (this yields structured, reliable results).
- Request visuals and output formats explicitly: specify charts (which axes, segments, units), and ask for reusable artifacts (clean tables, KPI MoM/YoY, slide bullets, or CSVs).
- Require transparency: ask for formulas, assumptions, and quick checks for missing data or spikes so you can spot-verify key numbers.
- Set analysis ground rules: instruct the model to avoid treating correlations as causation, flag data limitations, and call out anything that looks off.
Practical next steps
- Start by uploading a sample CSV and a one-line decision frame.
- Request a short EDA (3–5 prioritized observations) plus 5 follow-up analyses or hypotheses to test.
- Ask for one chart and a 3-line executive summary that maps findings to actions and risks.
Common tasks examples
- KPI dashboard: produce MoM + YoY table, 3 charts, and a 10-bullet exec summary with risks and recommended actions.
- Campaign review: compute conversion rate by channel, identify top drivers, and recommend optimizations.
- Anomaly detection & forecasting: flag suspicious rows, explain why, and produce a simple 8-week forecast with assumptions.
Keep outputs concise, request the checks you need to trust numbers, and always spot-verify a couple of key metrics before acting.
