Iterating Through Shapes

Iterate through each worksheet’s shapes in reverse order to safely remove them.

foreach (var section in content.Worksheets)
{
    for (int i = section.Shapes.Count - 1; i >= 0; i--)
    {
        // Check formatting criteria: red font color and Arial font family
        foreach (var fragment in section.Shapes[i].FormattedTextFragments)
        {
            if (fragment.ForegroundColor.Equals(Color.Red) && fragment.Font.FamilyName == "Arial")
            {
                // Remove the shape from the worksheet
                section.Shapes.RemoveAt(i);
                break; // Exit loop after removing a matching shape
            }
        }
    }
}

Saving the Updated Document

Save your changes to a new file once all unwanted shapes are removed.
