Quick Start

Create a new Excel file

from aspose_cells import Workbook

# Create a new workbook
workbook = Workbook()

# Get the first worksheet
worksheet = workbook.worksheets[0]

# Set cell values
worksheet.cells["A1"].put_value("Hello")
worksheet.cells["B1"].put_value("World")
worksheet.cells["A2"].put_value(42)
worksheet.cells["B2"].put_value(3.14)

# Save the workbook
workbook.save("output.xlsx")

Read an existing Excel file

from aspose_cells import Workbook

# Open an existing workbook
workbook = Workbook("input.xlsx")

# Access a worksheet
worksheet = workbook.worksheets[0]

# Read cell values
value = worksheet.cells["A1"].value
print(f"Cell A1 contains: {value}")

Apply styling

from aspose_cells import Workbook

workbook = Workbook()
worksheet = workbook.worksheets[0]
cell = worksheet.cells["A1"]

cell.put_value("Styled Text")

# Get and modify the cell style
style = cell.get_style()
style.font.is_bold = True
style.font.color = "FF0000"  # Red
style.font.size = 14
cell.set_style(style)

workbook.save("styled.xlsx")

Add data validation (dropdown list)

from aspose_cells import Workbook, DataValidationType

workbook = Workbook()
worksheet = workbook.worksheets[0]

# Add a dropdown list validation
validation = worksheet.data_validations.add()
validation.type = DataValidationType.LIST
validation.formula1 = '"Option1,Option2,Option3"'
validation.add_area("A1:A10")

workbook.save("validation.xlsx")

Export to CSV

from aspose_cells import Workbook, SaveFormat

workbook = Workbook("input.xlsx")
workbook.save("output.csv", SaveFormat.CSV)

Password protection

from aspose_cells import Workbook

workbook = Workbook()
worksheet = workbook.worksheets[0]
worksheet.cells["A1"].put_value("Confidential Data")

# Save with password protection
workbook.save("protected.xlsx", password="mypassword")

# Open a password-protected file
workbook2 = Workbook("protected.xlsx", password="mypassword")
