1）引入庫

• import openpyxl #引入整個庫，調用對應時使用openpyxl.xxx的形式
• from openpyxl import Workbook #引入Workbook對象，調用Workbook新建工作簿
• from openpyxl import load_workbook #引入load_workbook，導入已經建成的工作簿

2）新建工作簿

• wb = Workbook()
• wb = openpyxl.Workbook()

3）打開已有工作簿

• wb = load_workbook(‘sample.xlsx‘)
• wb = openpyxl.load_workbook(‘sample.xlsx‘)

4）獲得sheet控制句柄

• ws = wb.active #取得活動頁
• ws = wb.create_sheet(‘NewSheet‘) #在已有sheet位置後新建sheet
• ws = wb.create_sheet(‘NewSheet‘,0) #在已有sheet位置前新建sheet
• ws = wb[‘OldSheet‘] #獲得已有sheet

5）sheet屬性

• ws.title = ‘new title‘ #修改sheet名字
• ws.sheetnames #所有sheet名列表 例：print(ws.sheetnames) → [‘Sheet1‘, ‘New Title‘, ‘Sheet3‘]

6）循環-Sheet

for sheet in wb:
    print(sheet.title)

7）選取Cell

• c = ws[‘A4‘]
• ws[‘A4‘] = 8
• d = ws.cell(row=4, column=2, value=10)
• cell_range = ws[‘A1‘:‘C2‘]
• colC = ws[‘C‘]
• col_range = ws[‘C:D‘]
• row10 = ws[10]
• row_range = ws[5:10]
• ws.rows
• ws.columns

8）循環-Cell

>>> for row in ws.iter_rows(min_row=1, max_col=3, max_row=2):
...    
 
for cell in row:
...        print(cell)
<Cell Sheet1.A1>
<Cell Sheet1.B1>
<Cell Sheet1.C1>
<Cell Sheet1.A2>
<Cell Sheet1.B2>
<Cell Sheet1.C2>

>>> for col in ws.iter_cols(min_row=1, max_col=3, max_row=2):
...     for cell in col:
...         print(cell)
<Cell Sheet1.A1>
<Cell Sheet1.A2>
<Cell Sheet1.B1>
<Cell Sheet1.B2>
<Cell Sheet1.C1>
<Cell Sheet1.C2>

9）數據保存

>>> c.value = ‘hello, world‘
>>> print(c.value)
‘hello, world‘

>>> d.value = 3.14
>>> print(d.value)
3.14

>>> wb = Workbook(guess_types=True)
>>> c.value = ‘12%‘
>>> print(c.value)
0.12

>>> import datetime
>>> d.value = datetime.datetime.now()
>>> print d.value
datetime.datetime(2010, 9, 10, 22, 25, 18)

>>> c.value = ‘31.50‘
>>> print(c.value)
31.5

A）保存文件

• wb.save(‘sample.xlsx‘)
