Connect to Ollama from Excel and Word

On Microsoft Excel and Word, GPT for Work can connect to an Ollama server to use locally running open-source models. Ollama is an open-source platform that allows you to easily install, run, and serve models from a local machine, keeping your prompting entirely offline. You can use any model from the Ollama library.

note

Depending on the model you use, the model settings defined in GPT for Work (temperature (creativity), top-p, frequency penalty, and presence penalty) may not work as expected. If you get bad results, try tweaking the settings.

Connecting to Ollama in GPT for Work means setting the URL for the Ollama server and selecting one of the models available on the server.
