How to find your OpenAI API Key

Before you can start using the powerful GPT functions in Excel, you need to obtain an API key from OpenAI. This key will allow you to access the GPT models and integrate their capabilities into your Excel environment.

To find your OpenAI API Key, visit: Where do I find my OpenAI API key?

Once you have your API Key, follow these steps to configure it within XLTools:
  1. Navigate to the XLTools tab on your Excel ribbon.
  2. Click on Settings and select the GPT tab.
  3. Enter your OpenAI API Key in the designated text field.

Additionally, you can configure the following settings to optimize the performance and response of the GPT functions:

  • Model: Choose from a list of available GPT models. Each model has its own advantages, depending on whether you prioritize response speed, price, text complexity, or creative depth. Select the model that best fits your needs.
  • Max Tokens Allowed: Define the maximum number of tokens (pieces of words or punctuation) that GPT can generate in a single run. This helps manage processing time and resource use.
  • Temperature: Set the creativity level of the responses. A higher temperature value results in more creative and varied outputs, while a lower value produces more deterministic and predictable text.

With these settings configured, you are ready to utilize the GPT functions in your Excel workflows.

Tips and Tricks for Using GPT Functions in Excel

  • Apply a formula to a range of cells: You can apply a GPT function to a range of cells by entering the formula in the first cell and dragging the fill handle across the desired range. Excel will automatically adjust the formula for adjacent cells.

  • Build a prompt based on multiple cells with text data: To construct a dynamic prompt using data from multiple cells, use the CONCATENATE function or the '&' operator. For example, =GPT(CONCATENATE("Summarize the article on ", A1, " related to ", B1)).

  • Use conditional formatting with GPT functions: Enhance your spreadsheets by applying conditional formatting based on the output of GPT functions. This can help you visually categorize or prioritize data points.

  • Optimize performance by limiting real-time calls: GPT functions may require processing time. To optimize performance, especially in larger spreadsheets, consider limiting the use of real-time data processing or using manual calculation mode.
