Convert an Excel Worksheet to an Image in Python

You can easily convert a whole Excel worksheet to an image by using the Worksheet.SaveToImage() method provided by Spire.XLS for Python. The detailed steps are as follows:

• Create a Workbook object.
• Load an Excel file using Workbook.LoadFromFile() method.
• Get a specific worksheet by its index using Workbook.Worksheets[int index] property.
• Convert the worksheet to an image using Worksheet.ToImage() method.
• Save the image to a PNG file (you can also save the image as other image formats such as JPG and BMP).

from spire.xls import *
from spire.xls.common import *

# Create a Workbook object
workbook = Workbook()
# Load an Excel file
workbook.LoadFromFile("Sample.xlsx")

# Get the first worksheet
sheet = workbook.Worksheets[0]

# Save the worksheet to an image
image = sheet.ToImage(sheet.FirstRow, sheet.FirstColumn, sheet.LastRow, sheet.LastColumn)
# Save the image to a PNG file
image.Save("SheetToImage.png")
workbook.Dispose()

Convert an Excel Worksheet to an Image without White Margins in Python

When converting an Excel worksheet to an image, you may find the resulting image has unwanted white margins surrounding the cells. If you want to convert the worksheet to an image without any extraneous margins, you can remove the page margins set in the original worksheet. The detailed steps are as follows:

• Create a Workbook object.
• Load an Excel file using Workbook.LoadFromFile() method.
• Get a specific worksheet by its index using Workbook.Worksheets[int index] property.
• Remove all margins from the worksheet by setting its left, right, top, and bottom margin values to zero.
• Convert the worksheet to an image using Worksheet.ToImage() method.
• Save the image to a PNG file.

from spire.xls import *
from spire.xls.common import *

# Create a Workbook object
workbook = Workbook()
# Load an Excel file
workbook.LoadFromFile("Sample.xlsx")

# Get the first worksheet
sheet = workbook.Worksheets[0]

# Set all margins of the worksheet to zero
sheet.PageSetup.LeftMargin = 0
sheet.PageSetup.BottomMargin = 0
sheet.PageSetup.TopMargin = 0
sheet.PageSetup.RightMargin = 0

# Convert the worksheet to an image
image = sheet.ToImage(sheet.FirstRow, sheet.FirstColumn, sheet.LastRow, sheet.LastColumn)
# Save the image to a PNG file
image.Save("SheetToImageWithoutMargins.png")
workbook.Dispose()

Convert a Specific Cell Range to an Image in Python

In addition to converting a whole worksheet to an image, Spire.XLS for Python also supports converting a specific cell range of a worksheet to an image. The detailed steps are as follows:

• Create a Workbook object.
• Load an Excel file using Workbook.LoadFromFile() method.
• Get a specific worksheet by its index using Workbook.Worksheets[int index] property.
• Convert a specific cell range of the worksheet to an image using Worksheet.ToImage() method and pass the index of the start row, start column, end row, and end column of the cell range to the method as parameters.
• Save the image to a PNG file.

from spire.xls import *
from spire.xls.common import *

# Create a Workbook object
workbook = Workbook()
# Load an Excel file
workbook.LoadFromFile("Sample.xlsx")

# Get the first worksheet
sheet = workbook.Worksheets[0]

# Convert a specific cell range of the worksheet to an image
image = sheet.ToImage(5, 2, 17, 5)
# Save the image to a PNG file
image.Save("CellRangeToImage.png")
workbook.Dispose()
