What changed
- A preview under every workbook. When the chat builds an Excel model, you see its first rows and columns right in the conversation, formatted the way the workbook is, with a tab for each sheet. No download needed to check the numbers.
- It looks like Excel. The preview fills its frame with columns A to H, and a long note runs across the empty cells beside it instead of being cut short, the way it does in Excel. Numbers stay in their own cells.
- Open and edit in one click. The preview's Open and edit button opens the full workbook beside the chat, where you can change inputs and formulas straight away.
- Big models build in the background. A large request, such as a DCF across a whole portfolio, now builds while you keep working. A card shows what it is doing and how long it has been running, and the finished file and its preview appear in the same place when it is ready.
- Tidier answers. The same file is no longer listed twice in one reply.
Previews are free; building a model uses credits.
