python使用Openpyxl操作Excel文件的实现

sudo apt install python3

pip3 install openpyxl

from openpyxl import Workbook # 新建文件的引入
from openpyxl import load_workbook # 加载已存在文件的引入

wb = Workbook() # 创建一个新的工作簿
ws = wb.active # 获取活动工作表

wb.create_sheet("Sheet2") # 创建一个新的工作表并命名
ws.title = "NewSheet" # 修改工作表名

ws['A1'] = 'Hello, World!'
ws['B1'] = 42
ws['C1'] = 3.14
cell = ws.cell(row=1, column=1, value="New Value")

wb.save('example.xlsx')

wb = load_workbook('example.xlsx')
ws = wb.active

cell_a1 = ws['A1'].value
cell_b1 = ws['B1'].value
cell_c1 = ws['C1'].value

print(f"A1: {cell_a1}, B1: {cell_b1}, C1: {cell_c1}")

ws1 = wb.worksheets[0] # 通过索引选择工作表
ws2 = wb["Sheet2"] # 通过名称选择工作表

from openpyxl.styles import Font, Alignment # 样式操作的引入

font = Font(name='Arial', size=14, bold=True, italic=False)
ws['A1'].font = font

border = Border(left=Side(border_style='thin'),
                right=Side(border_style='thin'),
                top=Side(border_style='thin'),
                bottom=Side(border_style='thin'))
ws['A1'].border = border

fill = PatternFill(start_color="FF0000", end_color="FF0000", fill_type="solid")
ws['A1'].fill = fill

ws['B1'].number_format = '0.00%'   # 百分比格式
ws['C1'].number_format = 'YYYY-MM-DD'  # 日期格式

from openpyxl.worksheet.datavalidation import DataValidation

dv = DataValidation(type="list", formula1='"Apple,Banana,Cherry"', allow_blank=True) # 创建数据验证对象

ws.add_data_validation(dv) 
dv.add('A1') # 将数据验证应用到单元格

ws['D1'] = "=SUM(A1:A3)"

from openpyxl import load_workbook

wb = load_workbook('example.xlsx', read_only=True) # 使用只读模式加载工作簿

from openpyxl import Workbook

wb = Workbook(write_only=True) # 使用写入模式创建工作簿
ws = wb.create_sheet()

for row in ws.iter_rows(min_row=1, max_row=5, min_col=1, max_col=3):
    for cell in row:
        print(cell.value, end=" ")
