1. 读取文件
import openpyxl
# 加载文件
wb = openpyxl.load_workbook("example.xlsx")
# 获取所有单元簿的名称
wb.get_sheet_names()
# 获取单元簿
sheet = wb.get_sheet_by_name("Sheet1")
# sheet = wb["sheet"]
# 获取单元格的值
A1 = sheet["A1"]
print("row = ", A1.row, "column = ", A1.column, "value = ", A1.value)
B1 = sheet.cell(row=1, column=2)
# 获取多个单元格
for row in sheet["A1": "C3"]:
for cell in row:
print(cell.coordinate, cell.value)
# 获取一列
for cell in sheet.columns[1]:
print(cell.value)
# 确定表格的大小

# 列字母和数字的转换

2. 写文件

# 设置字体风格
from openpyxl.styles import Font, Style
# italic=斜体;bold=粗体
sheet["B1"].style = Style(font=Font(size=24, italic=True, bold=True))
# 设置公式
sheet["B5"] = "=SUM(B2: B4)"
# 设置行高宽
sheet["B5"].height = 20
sheet["B5"].width = 20
# 合并单元格
sheet.merge_cells("C5:D5")
sheet["C5"] = "合并单元格"
sheet.unmerge_cells("C5:D5")
# 添加图表
from openpyxl.charts import Reference, Series, BarChart
