import openpyxl

读取Excel文件

打开Excel文件

workbook = openpyxl.load_workbook("test.xlsx")

输出表单名字

# 输出工作簿中所有表单名字
print(workbook.sheetnames)
# 遍历所有表单并输出其名字
for sheet in workbook:
    print(sheet.title)

创建表单

newSheet = workbook.create_sheet("newSheetName")

获取表单对象

# 根据表单名获取表单
sheet3 = workbook.get_sheet_by_name("Sheet3")
sheet4 = workbook["newSheetName"]
# 获取当前活跃的表单
worksheet = workbook.active

获取当前表单数据行列数

# 获取当前表单数据行数
row_count = worksheet.max_row
# 获取当前表单数据列数
row_count = worksheet.max_column

获取单元格对象

selectcell = worksheet["A1"]
selectcell = worksheet.cell(row=1, column=2)    # 行列号从1开始

输出单元格信息

单元格所在的行、列

print(selectcell.row, selectcell.column)

单元格的坐标

print(selectcell.coordinate)

单元格的值

print(selectcell.value)

获取列对象

selectcol = worksheet["C"]

获取列对象中某一单元格

selectcell = selectcol["2"]

获取连续多列组成的对象

selectcols = worksheet["B:C"]

获取所有列组成的对象

allcol = worksheet.cols

获取行对象

selectrow = worksheet["2"]

获取行对象中某一单元格

selectcell = selectcol["C"]

获取连续多行组成的对象

selectcols = worksheet["1:4"]

获取所有行组成的对象

allrow = worksheet.rows

获取一定范围内的单元格组成的对象

cell_range = worksheet["A1:C3"]

遍历一定范围内的单元格

for row_range in cell_range:  #  先行再列
    for cell in row_range:
        print(cell.value)

行的字母表示与数字换算

from openpyxl.utils import get_column_letter, column_index_from_string
print(get_column_letter(2))) # 2 => B
print(column_index_from_string("C"))  # C => 3

编辑Excel文件

创建workbook对象

workbook = openpyxl.Workbook()

创建表单

workbook.create_sheet(index=1, title="第二张表")

删除表单

workbook.remove_sheet(workbook.get_sheet_by_name("Sheet3"))

获取当前活跃的表单

sheet = workbook.active

修改表单名称

sheet.title = "设置的表单名称"

修改单元格的值

sheet["A1"] = "New Value"

批量写入数据

方法一

import openpyxl
from openpyxl.utils import get_column_letter, column_index_from_string
workbook = openpyxl.Workbook()
ws1 = workbook.create_sheet("第一页")
for row in range(40):
    ws1.append(range(17))

方法二

import openpyxl
from openpyxl.utils import get_column_letter, column_index_from_string
workbook = openpyxl.Workbook()
ws2 = workbook.create_sheet("第二页")
rows = [
    ["Number", "Batch1", "Batch2"],
    [2,40,30],[3,50,25],
    [4,30,30],[5,60,10]
]
for row in rows:
    ws2.append(row)

方法三

import openpyxl
from openpyxl.utils import get_column_letter, column_index_from_string
workbook = openpyxl.Workbook()
ws3 = workbook.create_sheet("第三页")
for row in range(5,30):
    for col in range(15,24):
        ws3.cell(column=col, row=row, value=123)

修改完毕保存到文件

workbook.save("created.xlsx")
