excel.write_range(1, 1, [
    ["Product", "Quantity", "Price"],
    ["Apple", 10, 0.5],
    ["Banana", 15, 0.3],
    ["Orange", 8, 0.7]
])

# Calculate total for each product
excel.set_formula(2, 4, "=B2*C2")
excel.set_formula(3, 4, "=B3*C3")
excel.set_formula(4, 4, "=B4*C4")

# Calculate sum of quantities and total price
excel.sum_range(2, 2, 4, 2, 5, 2)  # Sum of quantities
excel.sum_range(2, 4, 4, 4, 5, 4)  # Sum of totals

# Calculate average price
