- Get the used range in the worksheet through Worksheet.AllocatedRange property.
- Set the background color of the used range through CellRange.Style.Color property.
- Save the workbook using Workbook.SaveToFile() method.
- Python
from spire.xls import *
from spire.xls.common import *
# Create an instance of Workbook class
wb = Workbook()
# Load an Excel file
wb.LoadFromFile("Sample.xlsx")
# Get a worksheet
sheet = wb.Worksheets.get_Item(0)
# Get the used range of the worksheet
usedRange = sheet.AllocatedRange
# Set the background color of the used range to a light and soft color
usedRange.Style.Color = Color.FromRgb(144, 238, 144)
# Save the workbook
wb.SaveToFile("output/ExcelBackgroundColor.xlsx", FileFormat.Version2016)
wb.Dispose()
Set the Background Image for an Excel Worksheet
Setting a background image for an Excel worksheet can be accomplished through PageSetup class. Using the Worksheet.PageSetup.BackgroundImage property, developers can set the image background for the entire worksheet. Detailed steps are as follows:

# Create an instance of Workbook class
wb = Workbook()
# Load an Excel file
wb.LoadFromFile("Sample.xlsx")
# Get a worksheet
sheet = wb.Worksheets.get_Item(0)
# Load an image
image = Stream("BackgroundImage.jpg")
# Set the background of the worksheet
sheet.PageSetup.BackgoundImage = image
# Save the workbook
wb.SaveToFile("output/ExcelBackgroundImage.xlsx", FileFormat.Version2016)

Insert Shapes in Excel in Python
You can add numerous types of shapes, such as lines, rectangles, triangles, and stars, to an Excel worksheet by using the Worksheet.PrstGeomShapes.AddPrstGeomShape() method provided by Spire.XLS for Python. Once added, you can customize the shapes, such as adding text to the shapes, filling the shapes with solid or gradient colors or images, and setting shadow styles for the shapes. The detailed steps are as follows.
- Create an object of the Workbook class.
- Get the first worksheet using Workbook.Worksheets[] property.
- Add a shape to the worksheet using Worksheet.PrstGeomShapes.AddPrstGeomShape() method.
- Add text to the shape using IPrstGeomShape.Text property.
- Fill the shape with a color using IPrstGeomShape.Fill.ForeColor property.
- Set the fill type of the shape as solid using IPrstGeomShape.Fill.FillType property.
- Repeat the above steps to add more shapes to the worksheet.
- Save the result file using Workbook.SaveToFile() method.
- Python
from spire.xls import *
from spire.xls.common import *
# Create a Workbook object
workbook = Workbook()
# Get the first worksheet
sheet = workbook.Worksheets[0]
# Add a triangle shape to the worksheet
triangle = sheet.PrstGeomShapes.AddPrstGeomShape(2, 2, 100, 100, PrstGeomShapeType.Triangle)
# Add text to the shape
triangle.Text = "Text"
# Fill the triangle with a solid color
triangle.Fill.ForeColor = Color.get_Yellow()
triangle.Fill.FillType = ShapeFillType.SolidColor
# Add a heart shape to the worksheet
heart = sheet.PrstGeomShapes.AddPrstGeomShape(2, 5, 100, 100, PrstGeomShapeType.Heart)
# Fill the heart with a gradient color
heart.Fill.ForeColor = Color.get_Red()
heart.Fill.FillType = ShapeFillType.Gradient
# Add an arrow shape with the default color to the worksheet
arrow = sheet.PrstGeomShapes.AddPrstGeomShape(10, 2, 100, 100, PrstGeomShapeType.CurvedRightArrow)
# Set shadow style for the arrow
arrow.Shadow.Angle = 90
arrow.Shadow.Distance = 10
arrow.Shadow.Size = 150
arrow.Shadow.Color = Color.get_Gray()
arrow.Shadow.Blur = 30
arrow.Shadow.Transparency = 1
arrow.Shadow.HasCustomStyle = True
# Add a cloud shape to the worksheet
cloud = sheet.PrstGeomShapes.AddPrstGeomShape(10, 5, 100, 100, PrstGeomShapeType.Cloud)
# Fill the cloud with a custom picture
cloud.Fill.CustomPicture(Image.FromFile("Hydrangea.jpg"), "Hydrangea.jpg")
cloud.Fill.FillType = ShapeFillType.Picture
# Save the result file
workbook.SaveToFile("InsertShapes.xlsx", ExcelVersion.Version2013)
workbook.Dispose()
