This is experimental. This demo lets you try xllify directly in your browser.

Use the chat panel on the right to describe a function or ask a question. The assistant will write the code for you. You can then refine it by continuing the conversation.

You can then call your function in the spreadsheet grid on the left. Try changing the formula or input values to test different behaviour. The grid is a simplified preview, not a full spreadsheet.

Chat responses are rate-limited. For the full experience, try the add-in in Excel.
