Once you have decided on a spreadsheet platform, it’s time to start incorporating ChatGPT to create a sample spreadsheet and fill it with dummy data.

Creating a New Spreadsheet

Before filling your spreadsheet with dummy data using ChatGPT, you need to create a new spreadsheet. This can be done using popular spreadsheet software like Microsoft Excel or Google Sheets.

This section will cover the steps for creating a new spreadsheet in both applications.

Microsoft Excel:

  1. Open Microsoft Excel and click on the “File” tab.
  2. Select “New” from the dropdown menu.
  3. Choose “Blank Workbook” to create a new, empty spreadsheet.

Google Sheets:

  1. Go to in your web browser.
  2. Click the “+Create” button to start a new spreadsheet.

Once you have created your new spreadsheet, organize your data by creating headers for your columns to help you and ChatGPT understand the type of data that will be filled in each column later.

Simple Copy&Paste Solution

You can easily create a spreadsheet with dummy data using the following prompt:

Create a dummy spreadsheet with four columns (Name, Age, Income, City) and fill it with 10 rows of dummy data. Format the resulting spreadsheet data as a table.

This tells ChatGPT to create a formatted HTML table that you can easily copy&paste into your spreadsheet (Google, Apple, Excel):

John Doe2845000New York
Jane Smith3555000Los Angeles
Mike Brown4260000Chicago
Lisa White2948000Houston
Tom Green5175000Phoenix
Susan Gray3952000Philadelphia
Ron Black2438000San Antonio
Alice Blue4564000San Diego

In the following, I’ll show you a more formal way of integrating ChatGPT in your spreadsheet software. 👇

Generating Dummy Data with ChatGPT

Using ChatGPT to generate sample data for your spreadsheet efficiently creates realistic and varied data. ChatGPT, available on platforms such as Google Workspace Marketplace, can fill your spreadsheet with the desired dummy data by following simple steps.

First, make sure you have connected ChatGPT to your spreadsheet application. If you are using Google Sheets, you can find the ChatGPT add-on in the Google Workspace Marketplace and follow the installation process. For Microsoft Excel, you can access ChatGPT via the OpenAI portal.

Once you have set up ChatGPT, decide on the type of data you want to generate. This may include text, numbers, dates, or a combination of these. Next, consider how you want the data to be structured. You can use ChatGPT to generate:

  • Random text strings
  • Sequential numbers
  • Date ranges
  • Email addresses
  • Phone numbers

To fill your spreadsheet with the desired sample data, select the cell or range of cells where the data will be placed. Then, use the appropriate ChatGPT function to generate your dummy data. You might specify the number of characters, the value range, or the formatting you want to apply.

For example, if you want to generate random names in column A, you can use the following formula:

=ChatGPT("generate_names", 10)

This will generate ten random names and fill the selected cells in column A.

Using ChatGPT, you can generate various types of sample data and customize the output to meet your specific needs, allowing you to create realistic and valuable dummy data for your spreadsheet projects.

Filling the Spreadsheet with Dummy Data

Once you have created a sample spreadsheet, fill it with realistic dummy data for testing. ChatGPT can assist with generating fake data that adheres to the structure and format of your target data.

To get started, integrate ChatGPT with your spreadsheet tool. For example, it’s possible to use ChatGPT with Google Sheets using Google Apps Script. This integration enables data fetch and formatting based on user-defined customization.

💡 Follow these five steps to generate and insert dummy data using ChatGPT:

  • Step 1: Connect your ChatGPT API with your preferred spreadsheet application.
  • Step 2: Identify the data fields that require dummy data, such as names, addresses, dates, or financial information.
  • Step 3: Construct appropriate ChatGPT prompts for generating the desired data. Keep in mind the desired format, style, and context.
  • Step 4: Execute the script to fetch and insert the generated data into the spreadsheet.
  • Step 5: Review and adjust the data as needed to ensure accuracy and coherence with the desired format.

Keep in mind that although ChatGPT can’t directly interact with Excel spreadsheets at the moment, it’s still possible to use this AI to generate the data and manually copy it into your spreadsheet. This process may be less automated, but it still significantly speeds up the data generation task.

Formatting and Organizing the Data

After creating a sample spreadsheet and filling it with dummy data using ChatGPT, the next important task is to format and organize the data to make it more readable and understandable. To begin, let’s explore some common formatting techniques available in spreadsheet tools such as Microsoft Excel and Google Sheets.

First, you can apply font formatting to your data. This includes changing the font style, size, and color. For example, you can make header cells bold by selecting the cells and clicking on the B icon in the toolbar or using the keyboard shortcut Ctrl+B.

Adjusting the text alignment is another useful option for organizing data. You can align the text to the left, center or right, depending on your preference. Additionally, you can change the vertical alignment of the content within the cells, making the data more visually appealing.

Conditional formatting is a powerful feature that can be used to highlight specific data points based on certain conditions or criteria. For example, you might want to highlight cells with values above a certain threshold, or change the background color of the cells with negative values. To use conditional formatting, simply select the range of cells you want to format, and then choose the appropriate option from the conditional formatting menu. In Microsoft Excel and Google Sheets, this can be found under the “Format” or “Home” tab.

Now, let’s consider ways to organize your data by using tables, bullet points, or other HTML tags:

  • Tables: Tables are perfect for organizing related data in a structured manner. To insert a table, go to the “Insert” tab and select “Table”, or use the keyboard shortcut Ctrl+T. You can then apply various formatting options, such as alternating row colors, to improve the readability of the data.
  • Bullet points: Using bullet points to list items is helpful when you have a series of tasks, conditions, or other non-tabular data points. In a cell, start with a hyphen followed by a space to create a bullet point. Simply press “Enter” to create a new bullet point in the same cell.
  • <a>, <strong>, <em>, and other HTML tags: You can use these tags directly in the content of the cells to give hyperlinks, bold, italic or underline effects, and more. Keep in mind that HTML tags are more compatible with Google Sheets than Microsoft Excel, which uses different syntax for such formatting.

Use these techniques to format and organize your data in a clear and understandable way, making it easier for you or others to analyze and interpret the information.


In summary, ChatGPT is a powerful tool that can help you create and fill a sample spreadsheet with dummy data. By providing clear prompts to the AI, you can obtain accurate and relevant data for your spreadsheet, making your work more efficient and less time-consuming. Utilizing ChatGPT for these tasks can greatly enhance your productivity and improve your overall spreadsheet management skills.

To get the most out of ChatGPT, it is essential to carefully craft your instructions and adjust your prompts based on the AI’s responses. This way, you ensure that the generated data is effectively tailored to your needs. Remember, practice makes perfect, so don’t hesitate to explore various prompt samples and combinations to achieve the desired results.

Moreover, ChatGPT’s potential goes beyond populating spreadsheets with dummy data. With its versatility and powerful language processing capabilities, it can be a valuable asset in various aspects of your work, such as Microsoft Excel data analysis or data science projects.
