XLSX

I'm trying to convert a HTML table to XLSX uisng AngularJS or even plain JavaScript. When I'm converting to XLS using below its downloading fine and a XLS file is opening. var blob = new Blob([template], {type: "data:application/vnd.ms-excel"}); window.navigator.msSaveOrOpenBlob(blob, "myExcel.xls"); But, my requirement wants the file in XLSX, so I changed the MIME type and extension of file in the same code like below, var blob = new Blob([template], {type: "data:application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"}); window.navigator.msSaveOrOpenBlob(blob, "myExcel.xlsx"); But

网上关于介绍Apache POI操作Excel的文章已经很多了，但都讲得比较复杂。poi的API 与实际使用中的Excel很类似，可以说是POI把Excel中的workbook、sheet、cell等对象化了，在实际使用中极易理解。但由于Apache POI在存在已有不短时间，至少在excel2007之前就已经出现，造成同样一套Api并不能同时读取(写入)xls和xlsx两种类型的Excel文件。但poi对excel有一个很好的抽象(ss包下的Workbook、Sheet、Cell等类)，可以一定程度上忽略xls/xlsx的处理细节，针对其通用部分进行处理，但如果需要对各自有理强的支持，还是建议使用相应的API。 Apache POI 各个包功能描述： HSSF － 提供读写Microsoft Excel XLS格式档案的功能。 XSSF － 提供读写Microsoft Excel OOXML XLSX格式档案的功能。 HWPF － 提供读写Microsoft Word DOC格式档案的功能。 HSLF － 提供读写Microsoft PowerPoint格式档案的功能。 HDGF － 提供读Microsoft Visio格式档案的功能。 HPBF － 提供读Microsoft Publisher格式档案的功能。 HSMF － 提供读Microsoft Outlook格式档案的功能

POI 简单介绍 Apache POI是 Apache软件基金会 的开放源码函式库，POI提供API给Java程序对Microsoft Office格式档案读和写的功能。 Apache POI 是创建和维护操作各种符合Office Open XML（OOXML）标准和微软的OLE 2复合文档格式（OLE2）的Java API。用它可以使用Java读取和创建,修改MS Excel文件.而且,还可以使用Java读取和创建MS Word和MSPowerPoint文件。Apache POI 提供Java操作Excel解决方案。 如果处理.xlsx、docx、pptx的话可以试试Docx4j 。 Docx4j is a Java library for creating and manipulating Microsoft Open XML (Word docx, Powerpoint pptx, and Excel xlsx) files. 基本功能 HSSF － 提供读写Microsoft Excel XLS格式档案的功能。 XSSF － 提供读写Microsoft Excel OOXML XLSX格式档案的功能。 HWPF － 提供读写Microsoft Word DOC格式档案的功能。 HSLF － 提供读写Microsoft PowerPoint格式档案的功能。 HDGF －

I´m trying to create a new excel workbook from R to save a few small datasets using xlsx package. For some reason it was working fine, but i´m unable to do it again. Code to create a new workbook library("xlsx") library("xlsxjars") library("rJava") file <- "marca_imei.xlsx" wb <- loadWorkbook(file) # The error: # Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl, : # java.lang.IllegalArgumentException: Your InputStream was neither an OLE2 stream, nor an OOXML stream I´ve searched for an answer but it seems people are having the same error when importing data from excel.

I have created dozens of data frames in R and would like to append them all to one sheet in an Excel file. Here are two of the pages I have looked at in an attempt to find an answer (I don't have 10 reputations so I can't paste all four webpage urls I have visited): Write data to Excel file using R package xlsx The author says: "You can also add the dataframes to a particular starting place in the sheet using the startRow and startCol arguments to the addDataFrame function." Here is the suggested code: workbook.sheets workbook.test addDataFrame(x = sample.dataframe, sheet = workbook.test, row

A couple of months ago I found on the Internet information about an R package to connect R with Excel and the other way around (doing basically what xlsx and XLConnect do). However, the main difference with respect to the two above mentioned solutions was that the package wasn't designed to use the JVM (which keeps giving me some trouble). I've been spending quite some time trying to find the reference for that package, without success. Can you help me? Many thanks.

I am trying to create cells comments using apache poi. I am able to create the comments, but by default they are always displayed in excel. I have to manual right click on the cell and un-tick show comments to make them invisible(now they appear only when I hover on the cell). Is it possible to make cell comments invisible by default(so that they don't appear in the excel until user hover over the cell.) Here is the code I used : Drawing drawing = cell.getSheet().createDrawingPatriarch(); CreationHelper factory = cell.getSheet().getWorkbook().getCreationHelper(); ClientAnchor anchor = factory

背景：在后台管理系统项目中，一般都会有将table表格导出为Excel，此文主要总结了如何实现该功能。 一、安装相关依赖 //xlsx 与 file-saver依赖 npm install --save xlsx file-saver 二、在main.js中引入以上安装好的组件 // vue中导出excel表格模板 import FileSaver from 'file-saver' import XLSX from 'xlsx' Vue.prototype.$FileSaver = FileSaver; //设置全局 Vue.prototype.$XLSX = XLSX; //设置全局 三、在组件中 补齐html ，并且在methods中写入方法 <template> <div class="driver-list-main"> <el-table id="out-table" ref="multipleTable" :data="tableData" :header-cell-style="{background:'#ccc',color: ' #333'}" :show-header="true" style="width: 100%" :highlightCurrentRow="true" > <el-table-column type="selection" width=
