Dynamically converting a list of Excel files to csv files in R

问题 I currently have a folder containing all Excel (.xlsx) files, and using R I would like to automatically convert all of these files to CSV files using the "openxlsx" package (or some variation). I currently have the following code to convert one of the files and place it in the same folder: convert("team_order\\team_1.xlsx", "team_order\\team_1.csv") I would like to automate the process so it does it to all the files in the folder, and also removes the current xlsx files, so only the csv files

问题 I have created dotnet application which is updating metadata (e.g. "Title" property) of XLSX file. I am using Microsoft.WindowsAPICodePack.Shell library in my application...which is perfectly updating metadata of that file on development environment. But on production server that application is not working. It is giving error like..... Microsoft.WindowsAPICodePack.Shell.PropertySystem.PropertySystemException (0x80004005): Unable to get writable property store for this property. Development

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 数据分析师肯定每天都被各种各样的数据数据报表搞得焦头烂额,老板的,运营的、产品的等等。而且大部分报表都是重复性的工作,这篇文章就是帮助大家如何用Python来实现报表的自动发送,解放你的劳动力,可以让你有时间去做更有意思的事情。 首先来介绍下实现自动报表要使用到的Python库: pymysql 一个可以连接MySQL实例并且实现增删改查功能的库 datetime Python标准库中自带的关于时间的库 openpyxl 一个可以读写07版以后的Excel文档(.xlsx格式也支持)的库 smtplib SMTP即简单邮件传输协议,Python简单封装成了一个库 email 一个用来处理邮件消息的库 为什么使用openpyxl库来处理Excel呢?因为它支持每个sheet的行数为100W+,也是支持xlsx格式的文件。如果你接受xls文件,并且每个sheet的行数小于6W,也是可以使用xlwt库,它对大文件的读取速度要大于openpyxl。 接下来我们就进入实战部分,来正式实现这个过程。我把整个实现过程分成几个函数的方式来实现,这样看着会比较有结构感。 首先导入所有要用到的库 编写一个传入sql就返回数据的函数get_datas(sql) 编写一个传入sql就返回数据的字段名称的函数get_datas(sql)

问题 Hello people of Stackverflow! I'm developing a small Android app which purpose is to read an .xlsx file and display its data in a certain form (bar/doughnut charts). As I don't have the time to learn everything I need in Java and Android I'm using Cordova & Ionic framework to do it. I'm pretty new to these (also pretty new to AngularJS) but I'm used to code in JavaScript, and already coded with NodeJS. So far I've managed to create a simple view which reads and display dummy data I created
