问题 How can I import a worksheet from a password-protected xlsx workbook into R ? I would like to be able to convert an Excel worksheet into a csv file without having to go through Excel itself. It is possible for xls workbooks using the perl-based function xls2csv from package gdata . I gather that the problem is Spreadsheet::XLSX doesn't support it. There are a variety of functions and packages for importing non-encrypted xlsx workbooks, but none seems to address this issue. At present it seems

Since the internal data of xlsx files is basically stored in separate xml files, I tried to recreate xlsx structure with all its files and subdirectories, compress them into a zip file and set its extension to xlsx. I use GDataXML parser/writer for creating all the necessary xml files. However, the file I get can't be opened as xlsx file. Even if I rip all the data from a valid xlsx file, create all the xml files manually by copying

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 报表工具的发展史，最早可以追溯到微软报表SSRS(SQL Server Reporting Services)时期。最初，报表工具主要应用于报表的定制、呈现和输出。经过几十年的发展，随着各种业务系统功能和结构的日趋复杂化，对报表工具“交互式、自助式、跨平台”的需求也在逐步攀升。 如今，一款优秀的报表工具，除了可以满足开发人员在不同的业务场景中，设计复杂结构报表和交互式报表的需求，还可以让开发人员将最大精力和时间投入到数据汇总、决策分析以及系统的UI表现层面。 葡萄城的 ActiveReports 报表，正是这些优秀的报表工具之一。作为一款专注于 .NET 平台的报表开发控件，ActiveReports已经为全球超过 300,000 名开发者提供全面的报表解决方案。 “经过二十余年发展历程，以及无数次版本更新迭代， ActiveReports 已经成为了市场上最受欢迎的 .NET报表控件之一，然而基于 .NET 架构的设计，使其很难做到与当下流行的Angular、React、Vue 等前端开发框架完美集成，如果我们推出一款同时具备强大的报表设计能力与前端框架完美兼容性的 纯前端报表控件 ，一定可以受到报表开发者的欢迎”葡萄城ActiveReports产品经理郭岚曾无数次表达出她对这款纯前端报表控件的期待。 终于
