How to Do Data Analysis in Google Sheets with ChatGPT

Cody Schneider

Wrestling with formulas in Google Sheets can feel like a full-time job. Instead of finding insights, you’re spending your time searching for the right combination of VLOOKUPs, QUERY functions, and pivot table settings. This guide will show you how to use ChatGPT as a smart assistant to speed up your data analysis in Google Sheets, helping you clean data, generate complex formulas, and uncover trends in your data without the headaches.

What Can You Actually Do with ChatGPT in Google Sheets?

Think of ChatGPT not as a replacement for Google Sheets, but as an on-demand data expert sitting next to you. You're still in the driver's seat, but you have a co-pilot who can instantly answer your questions. This partnership is especially powerful for automating the tedious and time-consuming parts of data analysis.

Here are the primary ways you can use ChatGPT to make your work in Google Sheets faster and more effective:

  • Formula Generation: This is the biggest win for most users. Instead of getting lost in help docs, you can just describe what you want to do in plain English. Ask for a formula to sum sales based on three different criteria, and ChatGPT will write the SUMIFS or QUERY function for you.

  • Data Cleaning and Formatting: Inconsistent data is a huge pain. Maybe your names are in all caps, you've got extra spaces, or you need to extract a ZIP code from a full address. You can ask ChatGPT for formulas to standardize text, split columns, or remove unwanted characters in seconds.

  • Summarizing Data and Spotting Trends: If you're not sure where to start, you can paste a small sample of your data and ask ChatGPT what it sees. It can point out potential trends, identify top performers, or suggest interesting questions you could ask of your data, giving you a starting point for your analysis.

  • Creating Sample Data: Need to test a formula or build a dashboard template without using real data? Just ask ChatGPT to generate a realistic-looking sample dataset with specific columns, and you'll have a placeholder ready to go in moments.

A Practical Workflow: From Raw Data to Insights

Let's walk through a common business use case: analyzing a simple sales report. Imagine you have a Google Sheet named "Sales Data" with the following columns:

  • Column A: OrderID

  • Column B: Date

  • Column C: Region (North, South, East, West)

  • Column D: Product Category (Electronics, Apparel, Home Goods)

  • Column E: Product

  • Column F: Units Sold

  • Column G: Sale Price

Step 1: Get Your Data Ready for ChatGPT

The single most important thing to remember is that ChatGPT cannot see your Google Sheet. It only knows what you tell it. The quality of your prompts will directly determine the quality of its answers. A lazy prompt like "help w/ sheets" won't get you anywhere. A great prompt sets the stage by providing clear context.

A good prompt should always include three things:

  1. The Goal: What are you trying to accomplish? (e.g., "I need to calculate total revenue for each region.")

  2. The Context: What are your column names and where is your data? (e.g., "My data is in a sheet called 'Sales Data' from A1:G500. Region is in Column C, Units Sold is in F, and Sale Price is in G.")

  3. The Format: How do you want the answer? (e.g., "Please provide a Google Sheets formula I can place in cell I2.")

Being specific saves you from frustrating back-and-forth conversations and helps ChatGPT give you the right answer on the first try.

Step 2: Use an AI Add-on for Google Sheets to Bring ChatGPT into Your Workflow

You can bring ChatGPT’s AI capabilities directly inside the apps you’re using. By enabling one of these add-ons for Google Sheets, you get a ton of ready-to-use custom functions that will do exactly what we’ve outlined next in our tutorial:

  • Get started by opening a new Google Sheet to check out a short introduction and copy the demo data to start playing with the add-in.

  • Enable ChatGPT in Google Sheets with one click to easily activate ChatGPT in Google Sheets in your existing sheet by going to Add-ons → GPT for Sheets and Docs → Enable GPT functions.

Once you are set up, explore your prompt capabilities to start analyzing your data - all right there in the spreadsheet.

Example 1: Cleaning Up Inconsistent Data

Let's say the text in your Product Category and Region columns is a mess. Some entries are in all caps ("NORTH"), some are lowercase ("apparel"), and others have random spacing. Let's fix it.

Your Prompt to ChatGPT (a custom cell in Sheets):"My 'Product Category' data in Column D is inconsistent. For example, I have 'electronics', 'ELECTRONICS', and ' Electronics '. I need a Google Sheets formula to standardize this text so it’s in proper case (e.g., 'Electronics') and any extra whitespace is removed."

ChatGPT's Response:It will likely suggest a formula combining TRIM and PROPER.

=PROPER(TRIM(D2))

You can then place this formula in a new column (say, H2), and drag it down to clean your entire dataset instantly. This simple task could take forever manually, but becomes a 30-second fix with a good prompt.

Step 3: Generating Complex Formulas You Don't Know How to Write

This is where ChatGPT really shines. Forget memorizing complicated syntax. Just describe the outcome you want, and let the AI do the heavy lifting. Let's start with a new goal: we want to find our total revenue (Units Sold * Sale Price) for a specific product category.

Example 2: Calculating Revenue with SUMPRODUCT

First, we need to multiply Units Sold (Column F) by Sale Price (Column G) for each row. A simple formula for that calculation would look like this: =ARRAYFORMULA(F2:F*G2:G).Since that gives us total revenue per order, we’ll ask our data analyst right inside of our sheet!

Your Prompt to ChatGPT:"I am analyzing sales data. 'Product Category' is in Column D, 'Units Sold' is in Column F, and 'Sale Price' is in Column G. Write me a Google Sheets formula to calculate the total revenue for the 'Apparel' category."

ChatGPT's Response:It will likely use the SUMPRODUCT function, which is perfect for this. It multiplies the corresponding items in two arrays (our units and prices) and then sums the products, but only if the category matches "Apparel".

=SUMPRODUCT(--(D:D="Apparel"), F:F, G:G)

Example 3: Building a Mini Report with the QUERY Function

The QUERY function is arguably the most powerful function in Google Sheets, but its syntax is intimidating for many. Let’s ask ChatGPT to create a summary report showing the total units sold for each product category within the 'North' region.

Your Prompt to ChatGPT:"Using my sales data sheet (A:G), write me a QUERY formula that shows the total units sold for each 'Product Category' (Column D). Only include sales where the 'Region' (Column C) is 'North'. The results should have two columns: one for the Product Category and one for the sum of 'Units Sold' (Column F). Please sort the results by the highest units sold."

ChatGPT's Response:=QUERY(A:G, "SELECT D, SUM(F) WHERE C = 'North' GROUP BY D ORDER BY SUM(F) DESC LABEL SUM(F) 'Total Units Sold'", 1)

Pasting this single formula into your sheet instantly creates a live summary table. It filters, aggregates, sorts, and even adds a clean column header for you - all from one plain-English request.

Step 4: Analyze and Interpret the Results

Formulas give you numbers, but insights come from interpretation. ChatGPT can act as a sounding board to help you make sense of your data. For this step, you would copy a small summary table (like the one QUERY just generated) from your sheet and paste it directly into the ChatGPT interface.

Your Prompt to ChatGPT:"I ran some analysis on my sales data. Here is a summary of the units sold for the 'North' region:"

Product Category

Total Units Sold

Electronics

4,500

Apparel

2,100

Home Goods

1,250

Based on this data, what are two key observations and one follow-up question I should investigate next?"

ChatGPT's Potential Response:_"Observation 1: Electronics are overwhelmingly the best-selling category in the North region, outselling Apparel by more than double.Observation 2: Home Goods are a distant third, representing a significantly smaller portion of sales.

Follow-up Question to Investigate:**Is the strong performance of Electronics in the North driven by a single high-performing product, or is there broad strength across the entire category? You should analyze sales at the individual 'Product' level within the Electronics category in the North region."_

This kind of prompt exchange shifts ChatGPT's role from a simple formula writer to a strategic partner, helping you think critically about what the data is actually telling you.

Important Limitations to Be Aware Of

While this workflow is powerful, it’s not magic. You need to be mindful of a few key limitations:

  • Data Privacy and Security: This is the big one. Never paste sensitive, confidential, or personally identifiable information into ChatGPT. This includes customer names, emails, financial records, or proprietary company data. Use it with anonymized or sample data only.

  • It Doesn't Have Live Access: Because ChatGPT can't see your sheet, your analysis is only as current as the data you give it. If your sheet updates in real-time, your analysis in the ChatGPT window will be outdated.

  • Occasional Inaccuracies ("Hallucinations"): ChatGPT can sometimes generate formulas that are syntactically correct but functionally wrong for your specific setup. Always double-check that the formula it provides actually makes sense and test it on a small scale before applying it to your entire dataset.

  • Context is Everything: Every time you start a new conversation on Chat GPT, it’s a relatively blank slate - it doesn’t recall past prompts you’ve provided unless this is part of a longer thread.

Final Thoughts

Using ChatGPT with Google Sheets can transform your data analysis workflow, turning hours of manual frustration into minutes of guided creation. By using natural language to clean data, generate formulas, and brainstorm ideas, you can move straight to uncovering the valuable insights hidden in your spreadsheets.

Manually copying data and walking AI through your needs is a huge step up, but it still involves a lot of friction. At Graphed, we wanted to eliminate that manual step entirely. We built a platform that connects directly to your data sources - like Google Analytics, Shopify, Facebook Ads, and more - so you never have to deal with downloading CSVs or copy-pasting samples again. You can ask for dashboards and insights in plain English, and have a rich, interactive visualization built from your live data in seconds, not a static formula in a spreadsheet.
