The following simple Python code demonstrates how easy it is to integrate IronXL in Python projects and read Excel files using it:
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()
