Yes, you can use GPT-3 in other Microsoft Office applications like Word or PowerPoint by using a similar approach as in Excel. You would need to write a script (such as in VBA) or use an add-in that connects to the OpenAI API and sends requests to GPT-3. The generated text can then be inserted into your Word document or PowerPoint presentation. Keep in mind that using GPT-3 in other Office applications might require a different level of technical expertise compared to Excel, depending on the method you choose.
