Hello Barbara,
I am sorry you had to experience this. To remove an embedded form from Excel;
Kindly try this;
- Place the mouse cursor over the chart's border. Do not place it within the chart; this may select individual chart elements, such as the legend box or headings.
- Click the mouse. Excel will select the chart, surrounding it with a thicker, light gray border.
- Press "Backspace" or "Delete." The embedded chart will vanish from the worksheet.

Many thanks, Dilly.
