用Python操作Excel实现办公自动化

pip install openpyxl

from openpyxl import load_workbook

# sheet相关操作

# 1.获取excel文件中的所有sheet名称

print(wb.sheetnames) # [‘数据导出‘, ‘用户列表‘, ‘Sheet1‘, ‘Sheet2‘]


# 2.选择sheet，基于sheet名称

sheet = wb["数据导出"]
cell = sheet.cell(1, 2)
print(cell.value)


# 3.选择sheet，基于索引位置

sheet = wb.worksheets[0]
cell = sheet.cell(1,2)
print(cell.value)


# 4.循环所有的sheet

for name in wb.sheetnames:
    sheet = wb[name]
    cell = sheet.cell(1, 1)
    print(cell.value)


for sheet in wb.worksheets:
    cell = sheet.cell(1, 1)
    print(cell.value)

# 1.获取第N行第N列的单元格(位置是从1开始）

cell = sheet.cell(1, 1)

print(cell.value)
print(cell.style)
print(cell.font)
print(cell.alignment)


# 2.获取某个单元格

c1 = sheet["A2"]
print(c1.value)

c2 = sheet[‘D4‘]
print(c2.value)


# 3.第N行所有的单元格

for cell in sheet[1]:
    print(cell.value)


# 4.所有行的数据（获取某一列数据）

for row in sheet.rows:
    print(row[0].value, row[1].value)


# 5.获取所有列的数据

for col in sheet.columns:
    print(col[1].value)

from openpyxl import load_workbook
