If you’re a data analyst, student, or someone learning analytics, you’ve probably realised one thing:
ChatGPT is not just a chatbot , it’s a powerful data analysis assistant.
From cleaning messy datasets to writing SQL queries, generating insights, and even creating charts, ChatGPT can help you work faster, think better, and automate a huge chunk of your workflow.
In this guide, you’ll learn exactly how to use ChatGPT for data analysis, with practical examples and prompts you can copy and paste today.
1. Use ChatGPT to Clean and Prepare Your Data
Cleaning data normally takes 60–80% of your time. ChatGPT cuts that time massively by:
- Suggesting cleaning steps
- Writing Python (Pandas) scripts
- Generating Excel formulas
- Handling missing values
- Standardizing columns
- Removing duplicates
Prompt Example
“Here is my dataset (paste sample rows). Clean it and write Python code in Pandas to:
– handle missing values
– fix inconsistent categories
– convert dates
– remove duplicates
– standardize column names
Return the final cleaned dataframe.”
Example Output You Can Expect
- Full explanation of the cleaning strategy
- Ready-to-run Python code
- Suggestions for improving data quality
2. Use ChatGPT for Exploratory Data Analysis (EDA)
ChatGPT can guide your entire EDA process or generate Python/SQL code to automate it.
It can:
- Describe patterns
- Detect outliers
- Suggest visualizations
- Summarize distributions
- Generate plots
Prompt Example
“Perform EDA on this dataset (paste sample).
Explain key patterns, outliers, trends, and correlations.
Suggest 5 possible insights a data analyst should explore further.”
3. Use ChatGPT to Generate Insights From Your Data
Even without coding, you can ask ChatGPT to interpret your data:
- What is driving performance?
- What correlations matter?
- What segments behave differently?
- What variables explain the results?
Prompt Example
“Explain what insights I can extract from this data. Provide business interpretation, not technical jargon.”
4. Use ChatGPT to Write SQL Queries for You
ChatGPT can translate plain English into complex SQL.
Examples of what it can write:
- JOIN queries
- Window functions
- Aggregations
- CTEs
- Case statements
- Data transformations
Prompt Example
“Write an SQL query to calculate monthly revenue, grouped by customer segment. Use a CTE and include year-over-year growth.”
ChatGPT will even debug your SQL if you paste an error message.
5. Use ChatGPT to Analyze Data in Excel or Google Sheets
If you work mostly in spreadsheets, ChatGPT helps with:
- Excel formulas
- Pivot table instructions
- Conditional formatting steps
- Data cleaning
- Lookups
- Statistical formulas
Prompt Example
“Write an Excel formula to extract the first name from a full name, even if the format is inconsistent.”
6. Use ChatGPT to Write Python Scripts for Data Analysis
Whether you’re new to coding or experienced, ChatGPT can generate:
- Pandas scripts
- Matplotlib and Seaborn visualizations
- Scikit-learn models
- Feature engineering pipelines
- Regex transformations
Example Prompt
**“Write Python code to:
- Load the dataset
- Compute summary statistics
- Create a correlation heatmap
- Plot the top 10 categories by frequency
- Save all charts as PNG files”**
7. Use ChatGPT to Build Dashboards and Reports
ChatGPT can:
- Suggest dashboard layouts
- Write Tableau/Power BI DAX
- Organize KPIs
- Generate narrative summaries
- Create business-friendly interpretations
Example Prompt
“Summarize this dataset into a business report with KPIs, trends, anomalies, and recommended actions for management.”
8. Use ChatGPT Advanced Data Analysis (File Uploads)
If you use ChatGPT with file-upload features, you can:
- Upload CSVs
- Run Python inside ChatGPT
- Generate visualizations
- Download cleaned datasets
- Produce statistical reports
It’s like having a lightweight Jupyter notebook inside the chat window.
