Spreadsheet Analysis with AI

You don't need to be an Excel guru. AI can analyze your data, write formulas, and explain what the numbers mean — all from a conversation.

Getting Data Into AI

You can paste tabular data directly into AI in several formats:

• •CSV (comma-separated values) — works everywhere
• •Markdown tables — clean and readable
• •Tab-separated text — copy directly from Excel or Google Sheets
• •Describe the data — "I have a spreadsheet with columns: Date, Product, Units Sold, Revenue, Region"

For large datasets, paste a sample (20-50 rows) and describe the full dataset's size and scope.

The Data Analysis Workflow

Step 1: Describe and Explore

"Here's my sales data for the last 12 months:

[paste data]

First, describe what you see in this data. What are the columns, how many rows, what's the date range, and are there any obvious data quality issues?"

Step 2: Ask for Insights

"Now analyze this data and tell me:

1. Overall trend (growing, declining, flat) with the growth rate

2. Best and worst performing months (and possible reasons)

3. Seasonal patterns or cyclical behavior

4. Average monthly revenue and standard deviation

5. The single most important insight a business owner should know"

Step 3: Get Specific

"Dig deeper into [the insight you found most interesting]:

- Is this statistically significant or just noise?

- What additional data would help confirm this pattern?

- What action should I take based on this?"

Formula Generation

AI is exceptional at writing spreadsheet formulas:

"I have a Google Sheet with these columns: A=Date, B=Product Name, C=Quantity, D=Unit Price, E=Total, F=Region, G=Sales Rep

Write formulas for:

1. Total revenue by region (SUMIFS)

2. Average order value per sales rep

3. Month-over-month growth percentage

4. Running total of revenue

5. Rank each sales rep by total revenue

For each formula, explain what it does in plain English and which cell to put it in."

Anomaly Detection

"Review this data and identify any anomalies:

[paste data]

For each anomaly explain:

- Why it stands out (statistically)

- Whether it's a one-time outlier or the start of a trend

- Possible causes

- Whether to investigate further or ignore it"

Data Cleaning Assistance

"This data has quality issues. Identify and suggest fixes for:

- Missing values (how many, which rows)

- Inconsistent formatting (e.g., dates in different formats)

- Duplicate entries

- Outliers that might be data entry errors

- Any logical inconsistencies (e.g., negative quantities)

Important Caveat

Always double-check AI's math on critical calculations. AI occasionally makes arithmetic errors, especially with complex multi-step calculations. For board-level or financial reporting, verify every number.
