Step-by-Step Guide

Clean and prepare data with ChatGPT

Upload your CSV or paste a sample of your dataset into ChatGPT with Code Interpreter. Ask it to: detect and fix formatting issues, identify outliers, fill missing values, standardize column names, and remove duplicates.

Pro tip: Prompt: "Clean this dataset: (1) detect and explain anomalies, (2) suggest how to handle each, (3) apply fixes, (4) show before/after summary. Prioritize preserving data integrity."

Run exploratory analysis with Gemini

Upload your dataset to Gemini. Its 1M context processes entire datasets at once. Ask for: distribution analysis, correlation matrices, trend identification, and summary statistics. Gemini generates visualizations and explains patterns in plain language.

Pro tip: Upload 3 datasets simultaneously and ask Gemini to join them, find correlations across all variables, and identify the top 5 insights a business leader should know.

Build interactive dashboards with AI

Describe your data and metrics. Ask ChatGPT to generate Python code for a Streamlit dashboard, Google Sheets formulas for live dashboards, or lookup formulas for Excel. Specify KPIs, filters, chart types, and update frequency.

Statistical analysis with Claude

Claude excels at rigorous statistical analysis. Upload your data and ask for: hypothesis testing, confidence intervals, regression analysis, A/B test evaluation, and significance testing. Claude explains methodology and limitations.

Pro tip: Prompt: "Run an A/B test analysis on this dataset. Calculate: conversion rates per variant, statistical significance (p-value), confidence intervals, minimum detectable effect, and recommend which variant to deploy."

Generate narrative insights with ChatGPT

Feed ChatGPT your cleaned data and analysis results. Ask for: executive summary, key findings, actionable recommendations, data storytelling narrative, and presentation-ready charts with annotations.

Automate recurring reports with Notion AI

Set up a Notion database connected to your data sources. Use Notion AI to: generate weekly summary reports, highlight changes from previous period, flag anomalies, and create action items based on data trends.

Pro Tips

Always use ChatGPT Code Interpreter for data analysis: it writes and runs Python code, generates plots, and handles files up to 512MB

Create a Data Analysis Playbook in Notion with standard prompts for common analyses (cohort analysis, funnel analysis, RFM segmentation, time series)

For sensitive data use Claude or a local LLM. Never upload PII or confidential data to public AI services

Build a prompt chain: Clean, Analyze, Visualize, Report. Each step feeds into the next for a complete data pipeline

Common Mistakes to Avoid

Mistake: Not validating AI-generated data cleaning steps

Fix: AI can introduce errors when cleaning data. Always ask for a summary of changes made and spot-check 10-20 rows before proceeding.

Mistake: Uploading sensitive or confidential data to public AI tools

Fix: Use Claude for sensitive data (better privacy policy) or run local LLMs like Llama or Mistral for truly confidential datasets.
