python 使用openpyxl操作excel文檔

學習代碼，僅供參考

# 讀取excel文件並輸出內容
import openpyxl as xl
import datetime
from openpyxl.chart import BarChart, Reference
from openpyxl.styles import PatternFill, Font

# 打開excel文件,獲取工作簿對象
wb = xl.load_workbook("example.xlsx")
# 從工作薄中獲取一個表單(sheet)對象
sheets = wb.sheetnames
# 打印工作項
print(sheets, type(sheets))
# 獲取激活工作項對象
ws = wb.active
# 激活項設置值
ws['A1'] = 1
# 寫入一個自定義的時間格式
ws['A2'] = datetime.datetime.now().strftime("%Y-%m-%d")
ws['A3'] = datetime.datetime.now()
# 設置樣式給單元格
ft = Font(name=u'微軟雅黑', size=11, bold=False, italic=False, vertAlign=None, underline='none', strike=False, color='FF000000')
fill = PatternFill(fill_type="solid", start_color='FFEEFFFF', end_color='FF001100')
ws["A1"].font = ft
ws["A2"].fill = fill

# 創建一個表單
sheet5 = wb.create_sheet('sheet4')

# 畫一個柱狀圖
for i in range(9):
    ws.append([i])
values = Reference(ws, min_col=1, min_row=1, max_col=1, max_row=9)
chart = BarChart()
chart.add_data(values)
ws.add_chart(chart, "A15")
# 保存上述修改
wb.save("example.xlsx")
