AI for Data Analysis: The Non-Technical Guide

You have spreadsheets full of data. You need insights. But you’re not a data scientist.

Good news: AI can help. Here’s how.

What AI Can Do With Your Data

Pattern Recognition

“What trends do you see in this sales data?”

Statistical Analysis

“What’s the average, median, and growth rate?”

Visualization

“Create a chart showing sales by month”

Anomaly Detection

“Are there any unusual values?”

Plain Language Insights

“Explain what this data tells us about customer behavior”

ChatGPT Advanced Data Analysis

What It Is

ChatGPT Plus includes Advanced Data Analysis (formerly Code Interpreter). Upload files, ask questions, get answers.

How to Use It

1. Open ChatGPT (Plus required)
2. Look for the paperclip icon or “Attach” option
3. Upload your CSV or Excel file
4. Ask questions in plain English

Example Workflow

You upload: sales_data.csv

You ask: “What are the main trends in this data?”

ChatGPT:

• Runs analysis code automatically
• Creates visualizations
• Explains findings in plain language

Real Examples

Basic analysis:

"Analyze this sales data. Tell me:
- Total revenue
- Best performing product
- Sales trend over time
- Any concerning patterns"

Specific question:

"Which customers haven't ordered in the last 90 days
but had more than $1000 in previous purchases?"

Then get specific based on what you learn.

Step 4: Iterate

“Can you break that down by region?” “What if we only look at the last 6 months?” “Show me the outliers”

ChatGPT can create:

• Charts (downloadable images)
• New spreadsheets with analysis
• Summary reports
