Edit a worksheet

On the Create tab, tick Edit existing sheet (tooltip: modify the current worksheet instead of replacing it). The hint shows whether the sheet is empty. Describe the change, then Generate Calculation.

Change a live sheet

1. Open the sheet you want to change.
2. Open AI Assistant → Create.
3. Tick Edit existing sheet.
4. Describe only the change — for example “add a plot of R versus L” or “convert results to USCS and add a summary table”.
5. Choose Generate Calculation.

Existing regions you did not ask to change should stay. Always walk the page after the status line reports that changes were applied, then run Evaluate. The status toast names how many operations succeeded and any that failed.

To replace the page instead of editing it, leave the box unticked — see Create a worksheet. After the assistant writes, run Evaluate so names follow evaluation order. For a human sign-off, use teams and review.
