Problem: One of the parameters in your GPT formula is required and hasn't been set.

Your API key is too limited​

Problem: If your OpenAI organization is using a free trial, the rate limits of your API key will be too low to be used in GPT for Excel.
Solutions

If you are not using an OpenAI free trial account​

Check that your OpenAI organization is correctly set in GPT for Excel:

  1. Select API keys from GPT for Excel sidebar menu.
  2. Enter your OpenAI organization ID in the format org-xxxxxxxxxxx, and click Save. This step is crucial if you are part of multiple organizations, as it ensures that billing for usage in GPT for Excel is attributed to the appropriate account.

    Important Note: To check if the organization you are using has remaining credits, follow these steps:

    1. Click on your user icon in the bottom left corner and select the appropriate organization.

    2. Go to Billing settings to check if you have remaining credits.

If you are using an OpenAI free trial account​

  • Option 1: Continue without an API key.
    This option is suitable for immediate use and if using your API key is not a priority. Select Continue without API key to clear it from GPT for Excel. Learn more about billing.
  • Option 2: Buy OpenAI credits for increased API rate limits.
    1. Go to OpenAI billing settings.
    2. Add your payment details.
    3. Purchase OpenAI credits starting at $5 to upgrade your account from the Free tier to Tier 1. This change increases your rate limit from 3 to 3,500 requests per minute with the gpt-3.5-turbo model. Note that TPM (Tokens Per Minute) limitations still apply, and further tier progression is necessary for greater TPM access.
    4. Wait up to 30 minutes for the new API key limit to become active.

OpenAI API not working with your key​

Problem: While your OpenAI API key is recognized as valid, it is not working due to one or more of the following reasons:

  • You haven't purchased OpenAI credits (if you're on a prepaid billing plan).
  • You haven't added a payment method to your OpenAI account (if you're on a legacy monthly billing plan).
  • Your default OpenAI organization isn't correctly set.
  • You have added a payment method or purchased OpenAI credits within the last 30 minutes and you still get this message.
Solutions
  1. Go to OpenAI billing settings.
  2. Add payment details.
  3. Purchase OpenAI credits.
  4. Go to API keys in GPT for Excel sidebar menu to ensure your OpenAI organization is correctly configured.
  5. Wait up to 30 minutes for your OpenAI API key to become active.
Solution for immediate use: If immediate use is needed and using your API key is not a priority, select Continue without API key to clear it from GPT for Excel. Learn more about billing.

Text values limited to 255 characters​

Text values in formulas are limited to 255 characters.

Problem: The text value in your formula is too long and exceeds Excel's 255-character limit.

Solution

Insert the text into another cell and reference it in your formula, for example, =GPT(A1), where A1 contains the text value.

Cell A1 contains a long prompt, and cell B1 contains =GPT(A1)
