1 Excel基本操作
获得行列基本信息，设置行列宽度，高度，字体等。
#!/usr/bin/env python3

import win32com.client
import os, sys, logging,re
from logging import debug, info
#logging.basicConfig( level = logging.DEBUG, format = '[%(filename)s %(lineno)d ] %(message)s')
logging.basicConfig( level = logging.DEBUG, format = ' %(message)s')
def get_full_name(name):
if ':' in name:
return name
else:
name = os.path.join(os.getcwd(), name)
return name
class Excel(object):
def __init__(self, filename ):
self.filename = get_full_name(filename)
self.sheetcount = 0
def open(self, name=''):
if(name!=''): self.filename = os.path.join(os.getcwd(), name )
self.excel = win32com.client.Dispatch("Excel.Application")
#可见
self.excel.Visible = 1
#book
self.excelbook = self.excel.Workbooks.Open(self.filename, ReadOnly=False)
info("open excel: %s", self.filename )
self.sheet = self.excelbook.Worksheets(self.excelbook.Worksheets.Count)
#self.excel.Workbooks.Add()
self.sheetcount = 1
##
info( self.sheet.cells( 3,1).Value ) #行,列
for i in range(1,10):
self.sheet.cells( i,3).Value = "hello world "+str(i)
#获取一列数据
self.sheet.Columns(1).Font.Bold = True #第一列加粗
self.sheet.Columns(1).Font.Name = "宋体" #字体
self.sheet.Columns(1).Font.Color = -16776961 #字体颜色
#设置列宽
print("列宽: ", self.sheet.Columns(1).ColumnWidth )
self.sheet.Columns(3).ColumnWidth = 30 #设置列宽
info("已经使用行数count : %s"%self.sheet.usedrange.rows.count )
info("已经使用列数count : %s"%self.sheet.usedrange.columns.count )
#获得一行数据
#info( self.sheet.Rows(1) )
self.sheet.Rows(1).RowHeight = 30 #设置行高度
def new_sheet(self, name=''):
if (self.sheetcount == 0): self.open()
#operate first sheet
self.sheet = self.excel.Worksheets.Add(None, self.sheet, 1) # (Before、After、Count、Type )
if ''!= name: self.sheet.Name = name
return self.sheet
def save(self):
info('saving excel: %s'%self.filename)
def close(self):
info("close excel: %s "%(self.filename))
if __name__ == '__main__':
test = Excel('1.xlsx')
test.open()
# test.new_sheet()
# test.new_sheet()
test.close()
效果如下：
2 合并单元格、取消单元格
#!/usr/bin/env python3
# -*- coding:GBK -*-

#logging.basicConfig( level = logging.DEBUG, format = '[%(filename)s %(lineno)d ] %(message)s')
logging.basicConfig( level = logging.DEBUG, format = ' %(message)s')
def RGB(r,g,b):
#奇怪的玩意和普通值反过来的
return int("%02x%02x%02x"%(b,g,r), 16)

if ':' in name:
return name
else:

return name

self.filename = get_full_name(filename)
self.sheetcount = 0
def open(self, name=''):
if(name!=''): self.filename = os.path.join(os.getcwd(), name )
self.excel = win32com.client.Dispatch("Excel.Application")
#可见
self.excel.Visible = 1
#book
self.excelbook = self.excel.Workbooks.Open(self.filename, ReadOnly=False)
info("open excel: %s", self.filename )
self.sheet = self.excelbook.Worksheets(self.excelbook.Worksheets.Count)
#self.excel.Workbooks.Add()
self.sheetcount = 1
##
info( self.sheet.cells( 3,1).Value ) #行,列
for i in range(1,10):
self.sheet.cells( i,3).Value = "hello"+str(i)
# self.sheet.Columns(3).HorizontalAlignment = -4152 #水平居中: -4108 靠右边: -4152 靠左:-4131
# self.sheet.Columns(3).VerticalAlignment = -4108 #垂直方向
# 水平靠右
self.sheet.Range("A1:C9").HorizontalAlignment = -4152
# 垂直居中
self.sheet.Range("A1:C9").VerticalAlignment = -4108
#合并单元格 B1,C1个单元格 Merge
self.sheet.Range("B1:D1").Merge(True)
#拆分单元格 UnMerge
self.sheet.Range("B1").UnMerge() #数据放在B1
self.sheet.Range("C1").UnMerge() #数据放在C1
#合并列一类类似调整Range范围即可
if __name__ == '__main__':
test = Excel('1.xlsx')
test.open()
3 对齐，数据格式设置
水平对齐
垂直对齐
#!/usr/bin/env python3
# -*- coding:GBK -*-
import win32com.client
import os, sys, logging,re
from logging import debug, info
#logging.basicConfig( level = logging.DEBUG, format = '[%(filename)s %(lineno)d ] %(message)s')
logging.basicConfig( level = logging.DEBUG, format = ' %(message)s')
def RGB(r,g,b):
#奇怪的玩意和普通值反过来的
return int("%02x%02x%02x"%(b,g,r), 16)
def get_full_name(name):
if ':' in name:
return name
else:
name = os.path.join(os.getcwd(), name)
return name
class Excel(object):
def __init__(self, filename ):
self.filename = get_full_name(filename)
self.sheetcount = 0
def open(self, name=''):
if(name!=''): self.filename = os.path.join(os.getcwd(), name )
self.excel = win32com.client.Dispatch("Excel.Application")
#可见
self.excel.Visible = 1
#book
self.excelbook = self.excel.Workbooks.Open(self.filename, ReadOnly=False)
info("open excel: %s", self.filename )
self.sheet = self.excelbook.Worksheets(self.excelbook.Worksheets.Count)
#self.excel.Workbooks.Add()
self.sheetcount = 1
##
info( self.sheet.cells( 3,1).Value ) #行,列
for i in range(1,10):
self.sheet.cells( i,3).Value = "hello"+str(i)
# self.sheet.Columns(3).HorizontalAlignment = -4152 #水平居中: -4108 靠右边: -4152 靠左:-4131
# self.sheet.Columns(3).VerticalAlignment = -4108 #垂直方向
# 水平靠右
self.sheet.Range("A1:C9").HorizontalAlignment = -4152
# 垂直居中
self.sheet.Range("A1:C9").VerticalAlignment = -4108
if __name__ == '__main__':
test = Excel('1.xlsx')
test.open()
4 边框设置，背景填充
Range对象
#!/usr/bin/env python3
# -*- coding:GBK -*-
import win32com.client
import os, sys, logging,re
from logging import debug, info
#logging.basicConfig( level = logging.DEBUG, format = '[%(filename)s %(lineno)d ] %(message)s')
logging.basicConfig( level = logging.DEBUG, format = ' %(message)s')
def RGB(r,g,b):
#奇怪的玩意和普通值反过来的
return int("%02x%02x%02x"%(b,g,r), 16)
def get_full_name(name):
if ':' in name:
return name
else:
name = os.path.join(os.getcwd(), name)
return name
class Excel(object):
def __init__(self, filename ):
self.filename = get_full_name(filename)
self.sheetcount = 0
def open(self, name=''):
if(name!=''): self.filename = os.path.join(os.getcwd(), name )
self.excel = win32com.client.Dispatch("Excel.Application")
#可见
self.excel.Visible = 1
#book
self.excelbook = self.excel.Workbooks.Open(self.filename, ReadOnly=False)
info("open excel: %s", self.filename )
self.sheet = self.excelbook.Worksheets(self.excelbook.Worksheets.Count)
#self.excel.Workbooks.Add()
self.sheetcount = 1
##
info( self.sheet.cells( 3,1).Value ) #行,列
for i in range(1,10):
self.sheet.cells( i,3).Value = "hello world "+str(i)
self.sheet.Columns(3).AutoFit() #自动调整列宽
#获取一列数据
self.sheet.Columns(1).Font.Bold = True #第一列加粗
self.sheet.Columns(1).Font.Name = "宋体" #字体
self.sheet.Columns(1).Font.Color = RGB(0,255,0) #字体颜色
#设置边框等信息
rg = self.sheet.Range( self.sheet.Cells( 1, 1 ), self.sheet.Cells(9,3) ) #获得一个Range对象
#rg = self.sheet.Range("A1:C9") #获得一个Range对象
rg.BorderAround( 1, 4 ) #边框线样式,线的粗细
rg.Borders.Color = RGB(0,0,0) #边框线颜色
rg.interior.color = RGB(255,0,0) #填充颜色
def save(self):
info('saving excel: %s'%self.filename)
def close(self):
info("close excel: %s "%(self.filename))
if __name__ == '__main__':
test = Excel('1.xlsx')
test.open()
test.close()
5 函数使用（自动求和…）
只能说官方文档还是强大！！！基本想要的Excel操作基本可以找到。
#!/usr/bin/env python3
# -*- coding:GBK -*-
import win32com.client
import os, sys, logging,re
from logging import debug, info
#logging.basicConfig( level = logging.DEBUG, format = '[%(filename)s %(lineno)d ] %(message)s')
logging.basicConfig( level = logging.DEBUG, format = ' %(message)s')
def RGB(r,g,b):
#奇怪的玩意和普通值反过来的
return int("%02x%02x%02x"%(b,g,r), 16)
def get_full_name(name):
if ':' in name:
return name
else:
name = os.path.join(os.getcwd(), name)
return name
class Excel(object):
def __init__(self, filename ):
self.filename = get_full_name(filename)
self.sheetcount = 0
def open(self, name=''):
if(name!=''): self.filename = os.path.join(os.getcwd(), name )
self.excel = win32com.client.Dispatch("Excel.Application")
#可见
self.excel.Visible = 1
#book
self.excelbook = self.excel.Workbooks.Open(self.filename, ReadOnly=False)
info("open excel: %s", self.filename )
self.sheet = self.excelbook.Worksheets(self.excelbook.Worksheets.Count)
#self.excel.Workbooks.Add()
self.sheetcount = 1
## 求第一列的和
for i in range(1,10):
self.sheet.cells( i,1).Value = i
#求和 ActiveSheet.Cells(2, 1).Formula = "=Sum(A1:A9)"
self.sheet.Cells(10,1).Formula = "=Sum(A1:A9)"
if __name__ == '__main__':
test = Excel('1.xlsx')
test.open()
效果：
