python 操作excel

介绍: 　　python 读写 excel 有好多选择，但是，方便操作的库不多，在我尝试了几个库之后，我觉得两个比较方便的库分别是 xlrd/xlwt、openpyxl。 　　之所以推荐连个库是因为这两个库分别操作的是不同版本的excel, xlrd 操作的是xls/xlxs 格式,的excel, 而 oppenpyxl 只支持 xlxs 格式的excel, openpyxl 使用起来会更方便一些, 所以如果你操作xlxs 文件的话, 那么可以优先选择openpyxl, 如果要兼容xls的话, 那就用xlrd/xlwt吧 本处使用openpyxl来实现 安装 pip install openpyxl 如果excel 里面有图片(jpg,png,bmg,..........) 需要安装图片处理模块\ pip install pillow excel写 from openpyxl import workbook wb = workbook() 创建一个新的工作薄 ws1 = wb.create_sheet("Mysheet") # 默认最后一个 ws2 = wb.create_sheet("Mysheet", 0) # 第一个 保存 wb.save("balances.xlsx") # 文件名 修改工作薄的名称 ws.title = New Title 获取所有的工作薄名称 print

问题 I would like to change the background color of a chart, as in this example, using openpyxl. In a google group discussion I found the following code snippet: from openpyxl.chart.shapes import GraphicalProperties props = GraphicalProperties(solidFill="999999") chart.graphical_properties = props chart.plot_area.graphical_properties = props but it does not have any effect on the chart when saved to the excel file. 回答1: This functionality was seemingly broken in a previous version of openpyxl and

Openpyxl updating sheet and maintaining graphs and images

问题 I just created a script with openpyxl to update a xlsx file that we usually update manually every month. It work fine, but the new file lost all the graphs and images that were in the workbook. Is there a way to keep them? 回答1: openpyxl version 2.5 will preserve charts in existing files. 回答2: Use xlwings instead, it works as a wrapper on pywin32 and can preserve the existing Excel graphs, pivot-tables, etc. 来源： https://stackoverflow.com/questions/37214983/openpyxl-updating-sheet-and
