模块导入
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")
