创建工作簿

from openpyxl as xl
# 实例化
wb = xl.WorkBook()
# 激活worksheet
ws = wb.active

读取

from openpyxl as xl
wb = xl.load_workbook('file_path')
# sheet的列表,工作簿中所有的工作表,返回**列表**
list_ws = wb.sheetnames
# 读取表格
ws = wb['Sheet']
# 获取表格最大行
row = ws.max_row
# 获取表格最大列
column = ws.max_column

创建表格

# 在最后插入表格
ws1 = wb.create_sheet('MySheet')
# 在指定位置插入表格
ws2 = wb.create_sheet("MySheet", 1) # 1是重左往右第二张表,根据列表的索引位置

访问

# 单一单元格访问
c = ws['A1'].value
d = ws.cell(row=4, column=2).value

# 多单元访问
cs = ws['A1': 'C2']
for i in cs:
    print(i.value)

cs1 = ws['A']  #访问列
for i in cs1:
    print(i.value)

cs2 = ws[10]  #访问行,范围是1到max_column
for i in cs2:
    print(i.value)

# 指定行列
for i in ws.iter_cols(min_row=1, max_col=3, max_row=3, min_col=2):
    for j in i:
        print(j)

字母与数字的相互转换

from openpyxl.utils improt get_column_letter, column_index_from_string
# 数字转字母
print(get_column_letter(2))  #B
# 字母转数字
print(column_index_from_string('D')) #4

删除工作表

del wb['Sheet']

矩阵置换

rows = [
    ['Number', 'data1', 'data2'],
    [2, 40, 30],
    [3, 40, 25],
    [4, 50, 30],
    [5, 30, 10],

设置单元格样式

字体

# 指定了等线(name)24号(size)，加粗斜体(blod)，字体颜色红色(color)。直接使用cell的font属性，将Font对象赋值给它
from openpyxl.styles import Font
bold_itatic_24_font = Font(name='等线', size=24, italic=True, color=colors.RED, bold=True)
sheet['A1'].font = bold_itatic_24_font

对齐方式

# 直接使用cell的属性aligment，这里指定垂直(vertical)居中和水平(horizontal)居中。除了center，还可以使用right、left等等参数
sheet['B1'].alignment = Alignment(horizontal='center', vertical='center')

行高,列宽

# 第2行行高
sheet.row_dimensions[2].height = 40
# C列列宽
sheet.column_dimensions['C'].width = 30

合并,拆分单元格

# 合并单元格， 往左上角写入数据即可
sheet.merge_cells('B1:G1')  # 合并一行中的几个单元格
sheet.merge_cells('A1:C3')  # 合并一个矩形区域中的单元格

sheet.unmerge_cells('A1:C3')  #拆分单元格

单元格背景色

from openpyxl.styles import PatternFill
fille = PatternFill('solid', fgColor='ffffff')  # 设置填充颜色为 橙色
sheet1.cell(row=2, column=8).fill = fille  # 序列
