问题 I have a similar question to this question(Javascript: Exporting large text/csv file crashes Google Chrome): I am trying to save the data created by excelbuilder.js 's EB.createFile() function.

《自拍教程64》Python Testlink用例导入拆分Excel工具

由 て烟熏妆下的殇ゞ 提交于 2020-05-09 16:07:03
案例故事： Testlink导入xml格式的用例过程中，还会碰到一个小问题： 如何尽量确保生成的xml尽量小于400kb呢，只能考虑对excel进行切割拆分了， 以下案例假设一个大的测试模块的Excel，内含1000条用例， 需要考虑用Python实现切割，切割拆分成5个子excel，每个Excel是200条左右, 当然如果某个测试模块的Excel，只包含200条以内的用例，肯定用不着切割了。 小提示：本案例不再考虑input.xlsx, output_1/2/3/4/5.xlsx这种输入输出的思维, 而采用python cut_excel.py 1000.xlsx 200 类似这种参数输入处理的形式, 其实很多命令行工具都是采用以上这种多参数实现处理的，比如adb, ffmpeg命令等。 准备阶段 准备一个包含1000条用例的excel表格，名字不限制， 比如取名为：1000.xlsx, 我们计划切割成10个小的Excel，每个Excel 100条， 参数输入，肯定涉及sys模块的argv参数的使用，以下是argv的使用示例： 命令 参数解析 python cut_excel.py 1000.xlsx 200 sys.argv=["cut_excel.py","1000.xlsx","200"]即： 参数0："cut_excel.py" 参数1："1000.xlsx" 参数2:

Is there any way to generate password protected XLSX in NodeJS?

由 扶醉桌前 提交于 2020-05-09 06:11:07
问题 I am looking for an npm package or any other workaround to be able to generate xlsx file with password. I do not want to protect the sheet(s) or cell(s)... I want the whole file password protected. I found few quite good packages (excel4node, exceljs..) but none of them able to do what I need. Any suggestion appreciated 回答1: You can use the xlsx-populate module to do this, for example: const XlsxPopulate = require('xlsx-populate'); XlsxPopulate.fromBlankAsync().then(workbook => { workbook

前言 报表工具是一个接近 20 年的产物了 但是，直到现在，在各种数据信息化的系统中，报表工具的作用，不仅没有褪色，反而是因为信息化需求的增大、数据的增多，以及报表工具本身迭代后越来越方便好用，使得它的使用范围越发的广泛了 报表选型也是一个老生常谈的话题了 但是，直到现在，依然有很多项目组，很多技术人员并不知道该怎样正确的选一个合适的报表，一个不会让自己在项目后期掉坑里的报表 本文全文 9990 字，大概需要 10-20 分钟阅读，旨在把这么多年总结下来的一些选型重点注意事项和验证技巧分享给需要做报表选型的技术同仁们，让我们选型变的更有重点，轻松又有保障 如果有想偷懒同学，也可以直接跳到文章尾部去看结论，也有完整的选型指标，和对应的重点注意事项表格供大家下载使用 常规选型的误区 常规的选型基本都是做一个功能需求列表（也可能从网上搜来），然后去找厂商应答，形式没问题，但很多需求列表却会有很多误区： l 陈年老列表，体现不出当前的新技术，有些指标还可能是错的 l 没有错但也没有用的废话列表，任何厂商都可以应答全部支持 l 没有想到重点要验证什么的列表，也都会被应答成全部支持，没有区分度 l 厂家散布在网络中的钓鱼列表，有些厂商的还算中肯，但也有些厂商会把把一些看似有用实则无用的所谓独有功能说成重点去误导选型 这是一个常规选型表开头的小部分，在这么短短几行中就能出现两个典型的误区
