Using Openpyxl to create multiple custom spreadsheets

问题 I'm trying to create a series of spreadsheets for my office based on criteria from a larger spreadsheet we have. This could very easily be done by hand, but since I am new to programming, I thought this could be a fun exercise to see if I could do it with python using the Openpyxl module. Basic problem: I have a list of countries people are traveling to, and I have rows with people's names and other data, including the name of the country each person is traveling to. The country each person

Export xlsx to csv in Angular

问题 I am using XLSX to parse data from an xlsx file. The problem is that when I try to get the data, the data is different depending on whether I read it in XLSX and CSV. I prefer to read it in CSV, since if I don't have to transform the dates according to the Excel format. I am trying to convert the XLSX file to CSV when the user uploads the file. The way I try is: const reader: FileReader = new FileReader(); reader.onload = (e: any) => { var binaryData = e.target.result; //Converting Binary

Convert xlsx (byte array) to csv(string) with javascript

问题 I am from c# so know nothing about java script. I have excel file (xlsx) that I red into byte array (with unity3d c# in webGL build) and want to send it into java script function that parse it into csv structure and return as string. So the question part is only related to java script that received xlsx as byte array(or any type from memory stream) and return csv as string. I need that function. What else (libs) do I need for that? (Update) The javascript code is MyConverterXlsxToCsvReturn:

Python中也可以写Excel中的“Vlookup”函数?太牛逼了吧!

Vlookup函数 ,可以算是一个数据专员必须要会使用的基本函数了,确实很好用。但是你可能会注意到,Excel一旦数据量过大,打开都费劲了,何况打开后,你还要输入公式计算,就更费劲了,此时你有没有想到过 被称作“万金油”的Python ,他好像啥都可以做,是不是很牛逼?对于Excel来说的大数据量,但是对于Python来说,应该是小菜一碟。 今天我就带着大家对比学习一下,怎么分别在Excel和Python中使用Vlookup函数。 数据源介绍 如图所示,有一个“vlookup.xlsx”文件,“A1:F11”是我们的数据源区域,“K1:L5”是我们的查找源区域。我们的目的就是要在数据源区域的G列加一列数据,查找出不同类型下名称表示。 Vlookup函数介绍 这个函数我想大家应该都会,大家应该也不需要我介绍的太详细,因此我就简单的为大家介绍一下vlookup函数的语法。 参数说明:vlookup(待查找目标, 查找区域, 匹配值所在的列, 精确匹配OR模糊查找); 用一句通俗的话来说明vlookup函数的用法:针对每一个待查找目标,它就能从指定的查找区域中,查找返回想要查找到的值。 Excel中使用Vlookup函数 针对上述提到的数据源,了解Vlookup函数的语法后,下面来看看如何在Excel中使用Vlookup函数。 观察上图:首先,我们在G1单元格 新增了一个“名称”列

问题 I'm pretty new at more than simple spreadsheet use and could use some help. I've been told that I can use /n instead of CHAR(10) in concatenate forumla but am finding that simply replacing it with /n is not working. =CONCATENATE(B1," "&CHAR(10)," "&C1," "&CHAR(10)," "&CHAR(10),D1,""&CHAR(10)) Could somebody please show me what this should look like? Explaining might be helpful, but won't help without seeing the full result as I don't understand half the jargon. Thanks in advance. 回答1: I think
