from ironxl import *      

# Load existing Excel file (workbook)
workbook = WorkBook.Load("sample.xlsx")

# Select worksheet at index 0
worksheet = workbook.WorkSheets[0]

# Get any existing worksheet
first_sheet = workbook.DefaultWorkSheet

# Select a cell and return the converted value
cell_value = worksheet["A2"].IntValue

# Read from a range of cells elegantly
for cell in worksheet["A2:A10"]:
    print("Cell {} has value '{}'".format(cell.AddressString, cell.Text))

# Calculate aggregate values such as Sum
total_sum = worksheet["A2:A10"].Sum()

from ironxl import *      

# Load existing Excel file (workbook)
workbook = WorkBook.Load("sample.xlsx")

# Select worksheet at index 0
worksheet = workbook.WorkSheets[0]

# Get any existing worksheet
first_sheet = workbook.DefaultWorkSheet

# Select a cell and return the converted value
cell_value = worksheet["A2"].IntValue

# Read from a range of cells elegantly
for cell in worksheet["A2:A10"]:
    print("Cell {} has value '{}'".format(cell.AddressString, cell.Text))

# Calculate aggregate values such as Sum
total_sum = worksheet["A2:A10"].Sum()

Key Considerations for Selection

Primary Task: Identify your primary task—data analysis (Pandas), read/write operations with formatting (OpenPyXL), or in-depth Excel automation (IronXL).

Data Volume: Consider the size of your datasets—Pandas excels with performance for massive datasets, while OpenPyXL and IronXL may offer better file size management.

Formatting Requirements: If intricate formatting control is crucial, prioritize OpenPyXL and IronXL over Pandas.

Cost: Pandas and OpenPyXL are free and open-source, while IronXL requires a commercial license.
