Apply borders to all cells in a range with openpyxl

心不动则不痛 提交于 2019-11-30 15:17:53
I have a script that takes a pandas dataframe and chops it up into several hundred chunks and saves each chunk as a separate excel file. Each chunk will have the same number of columns but the number of rows varies. I've figured out how to apply all the other necessary formatting to these files with openpyxl, but I haven't yet determined the fastest way to apply borders. Also, I think I'm just not applying borders correctly, because the code below (which I suspect shouldn't need to loop over each cell individually) doesn't apply any borders. from openpyxl.style import Border wb = load_workbook

Protecting Workbook in openpyxl

喜欢而已 提交于 2019-11-30 15:00:00
I try to protect an Excel workbook with openpyxl. So far I had a look into the different, potentially relevant classes but I can't find a set_password method like the one for worksheets . There happens to be the workbook.protection module that I tried my luck with. My code, boiled down to the absolute relevant minimum is as follows: from openpyxl import Workbook from openpyxl.workbook.protection import WorkbookProtection wb = Workbook() wb.security = WorkbookProtection(workbookPassword='0000', revisionsPassword = '0000', lockWindows = True, lockStructure = True, lockRevision = True) wb.create

用python库openpyxl操作excel,从源excel表中提取信息复制到目标excel表中

现代生活中,我们很难不与excel表打交道,excel表有着易学易用的优点,只是当表中数据量很大,我们又需要从其他表册中复制粘贴一些数据(比如身份证号)的时候,我们会越来越倦怠,毕竟我们不是机器,没法长时间做某种重复性的枯燥操作。想象这样一个场景,我们有个几千行的表要填,需要根据姓名输入其对应的身份证号,但之前我们已经做过一个类似的表,同样的一些人的姓名跟身份证号是完整的,那么我们就需要通过一个个查找姓名,然后把身份证号码复制到我们当前要做的表里去。 当我日复一日重复着这些操作的时候,我都很想有一个自动化工具来完成这种操作,把做为人的我从这种非人的折磨里解脱出来,最后还是想到了python,因为这样我能很少的关注语言内部的一些细节,从而专注于解决这个问题。 其安装命令为 pip install openpyxl(在线安装)或者 easy_install openpyxl。 openpyxl的操作可以分四步,第一步载入现有workbook或者创建workbook到内存,分别使用 from openpyxl import load_workbook from openpyxl import Workbook #载入现有workbook中 wb1=load_workbook('lalala.xlsx') """ 在源表数据量很大的时候,这里我们可以使用openpyxl的read

问题 I have to create and write a new excel workbook with about 5 worksheets. The purpose of my code is to read a database and split that into different sheets depending on certain criterion.

openpyxl openpyxl可以用来对excel进行操作,但只能操作xlsx文件而不能操作xls文件。 主要用到三个概念:Workbooks,Sheets,Cells。 Workbook就是一个excel工作薄; Sheet是工作表中的一张工作表; Cell就是简单的一个格。 openpyxl就是围绕着这三个概念进行的:打开Workbook,定位Sheet,操作Cell。 读取与创建 读取Workbooks 可以导入openpyxl.load_workbook()来打开一个已经存在的workbook: >>> from openpyxl import load_workbook >>> wb2 = load_workbook('test.xlsx') >>> print wb2.get_sheet_names() ['Sheet2', 'New Title', 'Sheet1'] 创建Workbooks与Sheets 在刚开始使用openpyxl的时候,不需要直接在文件系统中创建一个文件,仅仅需要导入Workbook类并开始使用它: >>> from openpyxl import Workbook >>> wb = Workbook() 一个workbook总是会创建至少一个worksheet(工作表),可以通过openpyxl.workbook.Workbook

openpyxl模块介绍 openpyxl模块是一个读写Excel 2010文档的Python库,如果要处理更早格式的Excel文档,需要用到额外的库,openpyxl是一个比较综合的工具,能够同时读取和修改Excel文档。其他很多的与Excel相关的项目基本只支持读或者写Excel一种功能。 安装openpyxl模块 pip3 install openpyxl openpyxl基本用法  想要操作Excel首先要了解Excel 基本概念,Excel中列以字幕命名,行以数字命名,比如左上角第一个单元格的坐标为A1,下面的为A2,右边的B1。   openpyxl中有三个不同层次的类,Workbook是对工作簿的抽象,Worksheet是对表格的抽象,Cell是对单元格的抽象,每一个类都包含了许多属性和方法。 操作Excel的一般场景: 打开或者创建一个Excel需要创建一个Workbook对象 获取一个表则需要先创建一个Workbook对象,然后使用该对象的方法来得到一个Worksheet对象 如果要获取表中的数据,那么得到Worksheet对象以后再从中获取代表单元格的Cell对象 Workbook对象 一个Workbook对象代表一个Excel文档,因此在操作Excel之前,都应该先创建一个Workbook对象。对于创建一个新的Excel文档

Applying borders to a cell in OpenPyxl

I am trying to use Openpyxl to apply a border to a cell, but I have failed on the most basic "apply any kind of border to any cell anywhere" task. I tried copying from the Openpyxl documentation ( http://pythonhosted.org/openpyxl/styles.html#introduction ) default style and modifying, but that gives me "TypeError: init () got an unexpected keyword argument 'superscript'" I tried copying straight out of another example here ( Apply borders to all cells in a range with openpyxl ), but that gives me AttributeError: type object 'Border' has no attribute 'BORDER_THIN' (even after I fix the typos
