1、openpyxl库可以读写xlsx格式的文件,对于xls旧格式的文件只能用xlrd读,xlwt写来完成了。
简单封装类:
from openpyxl import load_workbook from openpyxl import Workbook from openpyxl.chart import BarChart, Series, Reference, BarChart3D from openpyxl.styles import Color, Font, Alignment from openpyxl.styles.colors import BLUE, RED, GREEN, YELLOW class Write_excel(object): def __init__(self,filename): self.filename = filename self.wb = load_workbook(self.filename) self.ws = self.wb.active def write(self, coord, value): # eg: coord:A1 self.ws.cell(coord).value = value self.wb.save(self.filename) def merge(self, rangstring): # eg: rangstring:A1:E1 self.ws.merge_cells(rangstring) self.wb.save(self.filename) def cellstyle(self, coord, font, align): cell = self.ws.cell(coord) cell.font = font cell.alignment = align def makechart(self, title, pos, width, height, col1, row1, col2, row2, col3, row3, row4): ''':param title:图表名 pos:图表位置 width:图表宽度 height:图表高度 ''' data = Reference(self.ws, min_col=col1, min_row=row1, max_col=col2, max_row=row2) cat = Reference(self.ws, min_col=col3, min_row=row3, max_row=row4) chart = BarChart3D() chart.title = title chart.width = width chart.height = height chart.add_data(data=data, titles_from_data=True) chart.set_categories(cat) self.ws.add_chart(chart, pos) self.wb.save(self.filename)
简单使用:
1、新建excel文件处理
wb = Workbook()#创建工作簿 ws = wb.active#激活工作表 ws1 = wb.create_sheet("Mysheet")#创建mysheet表 ws.title = "New Title"#表明改为New Title ws.sheet_properties.tabColor = "1072BA"#颜色 ws['A4'] = 4#赋值 d = ws.cell(row=4, column=2, value=10)#赋值 cell_range = ws['A1':'C2']#选择单元格区域 wb.save('test.xlsx')#保存
2、已有excel文件的处理
a、修改excel数据
wr = Write_excel('d:\demo.xlsx') wr.write('A2','hello')
b、合并单元格
wr.merge('A1:B3')
c、单元格加入样式,如字体,颜色等属性
单元格B2设置宋体,14号,红色,自动换行,水平居中,垂直居中
font = Font(name=u'宋体', size=14, color=RED, bold=True) align = Alignment(horizontal='center', vertical='center') wr.cellstyle('B2', font, align)
d、创建3d柱状图
rows = [ (None, 2013, 2014), ("Apples", 5, 4), ("Oranges", 6, 2), ("Pears", 8, 3) ] for row in rows: ws.append(row) wr.makechart(u"3D Bar Chart", 'E5', 12.5, 7, 2, 1, 3, 4, 1, 2, 4)
可以创建3d柱状和折线图表,挺好用的。
