1.openpyxl寫入數據
例子1:

import openpyxl
f = openpyxl.Workbook()
table = f.active

table['A2'] = 4
table['A1'] = 5

table.cell(row = 3,column = 1,value = 10)
table.cell(row = 4,column = 1, value = 11)

# 添加一列數據
row = [1,2,3,4,5]
for i in row:
    table.append([i])

# 添加多行
rows = [
    ['Number', 'data1', 'data2'],
    [2, 40, 30],
    [3, 40, 25],
    [4, 50, 30],
    [5, 30, 10],
    [6, 25, 5],
    [7, 50, 10],
]
for row in rows:
    table.append(row)

#添加一列數據
values = ['abc','edfe', 'apples', 'bananas'] 
for item in values: 
    table.append([item]) 

f.template = True
f.save('data/demo.xlsx')

例子2:

from openpyxl import Workbook
from openpyxl.worksheet.table import Table, TableStyleInfo

wb = Workbook()
ws = wb.active

data = [
    ['Apples', 10000, 5000, 8000, 6000],
    ['Pears',   2000, 3000, 4000, 5000],
    ['Bananas', 6000, 6000, 6500, 6000],
    ['Oranges',  500,  300,  200,  700],
]

# add column headings. NB. these must be strings
ws.append(["Fruit", "2011", "2012", "2013", "2014"])
for row in data:
    ws.append(row)

tab = Table(displayName="Table1", ref="A1:E5")

# Add a default style with striped rows and banded columns
style = TableStyleInfo(name="TableStyleMedium9", showFirstColumn=False,
                       showLastColumn=False, showRowStripes=True, showColumnStripes=True)
tab.tableStyleInfo = style
ws.add_table(tab)
wb.save("data/table.xlsx")

txt文件轉換爲xlsx

2.openpyxl讀取數據

from openpyxl import load_workbook
wb = load_workbook('data/demo.xlsx')
#print(wb.get_sheet_names())

#a_sheet = wb.get_sheet_by_name('Sheet')
#print(a_sheet.title)
sheet = wb.active
b4 = sheet['A4']
print(b4.value)

b4_too = sheet.cell(row = 4,column = 1)
print(b4_too.value)

# =============================================================================
# # A1, A2, A3這樣的順序
# for column in sheet.columns:
#     for cell in column:
#         print(cell.value)
# =============================================================================

#讀取一列數據        
for cell in list(sheet.columns)[0]:
    print(cell.value)
