Python中几种存取xls/xlsx文件的方法总结

import xlwt

workbook = xlwt.Workbook(encoding='utf-8')

booksheet = workbook.add_sheet('Sheet 1', cell_overwrite_ok=True)

#存第一行cell(1,1)和cell(1,2)

booksheet.write(0,0,34)

booksheet.write(0,1,38)

#存第二行cell(2,1)和cell(2,2)

booksheet.write(1,0,36)

booksheet.write(1,1,39)

#存一行数据

rowdata = [43,56]

for i in range(len(rowdata)):

 booksheet.write(2,i,rowdata[i])

workbook.save('test_xlwt.xls')

import xlrd

workbook = xlrd.open_workbook('D:\\Py_exercise\\test_xlwt.xls')

print(workbook.sheet_names())  #查看所有sheet

booksheet = workbook.sheet_by_index(0) #用索引取第一个sheet

booksheet = workbook.sheet_by_name('Sheet 1') #或用名称取sheet

#读单元格数据

cell_11 = booksheet.cell_value(0,0)

cell_21 = booksheet.cell_value(1,0)

#读一行数据

row_3 = booksheet.row_values(2)

print(cell_11, cell_21, row_3)

>>>34.0 36.0 [43.0, 56.0]

from openpyxl import Workbook

workbook = Workbook()

booksheet = workbook.active #获取当前活跃的sheet,默认是第一个sheet

#存第一行单元格cell(1,1)

booksheet.cell(1,1).value = 6 #这个方法索引从1开始

booksheet.cell("B1").value = 7

#存一行数据

booksheet.append([11,87])

workbook.save("test_openpyxl.xlsx")

from openpyxl import load_workbook

workbook = load_workbook('D:\\Py_exercise\\test_openpyxl.xlsx')

#booksheet = workbook.active #获取当前活跃的sheet,默认是第一个sheet

sheets = workbook.get_sheet_names() #从名称获取sheet

booksheet = workbook.get_sheet_by_name(sheets[0])

rows = booksheet.rows

columns = booksheet.columns

#迭代所有的行

for row in rows:

 line = [col.value for col in row]

#通过坐标读取值

cell_11 = booksheet.cell('A1').value

cell_11 = booksheet.cell(row=1, column=1).value
