XLSX

I want to read an xlsx file that was created in Microsoft Excel, but when I run the following code... $Source_File = "test.xlsx"; $Spreadsheet = \PhpOffice\PhpSpreadsheet\IOFactory::load($Source_File); ...I receive the following error: Fatal error: Uncaught PhpOffice\PhpSpreadsheet\Reader\Exception: Unable to identify a reader for this file in /var/www/html/vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/IOFactory.php:163 Stack trace: #0 /var/www/html/vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/IOFactory.php(93): PhpOffice\PhpSpreadsheet\IOFactory::createReaderForFile('file:///home

I want to print an Excel file to a pdf file after manipulating it. For the manipulation I used the .xlsx package which works fine. There is a function printSetup but I cannot find a function to start the printing. Is there a solution for this? library(xlsx) file <- "test.xlsx" wb <- loadWorkbook(file) sheets <- getSheets(wb) # get all sheets sheet <- sheets[[1]] # get first sheet # HERE: MAGIC TO SAVE THIS SHEET TO PDF It may be a solution using DCOM through the RDCOMClient package, though I would prefer a plattform independent solution (e.g. using xlsx ) as I work on MacOS. Any ideas? Below a

I'm trying to use POI.APACHE to edit excel files in java. I have to convert a .xls to .xlsx because I need to send the file to sharepoint. Thats why it just can't be renamed with a different extension. How would I go about this? I couldn't find any examples on their site. Thanks import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.IOException; import java.io.InputStream; import java.io.OutputStream; import java.util.Iterator; import org.apache.poi.hssf.usermodel.HSSFWorkbook

I have a xlsx with only one spreadsheet. I use PHPExcel to convert it to a pdf through the following code: error_reporting(E_ALL); date_default_timezone_set('Europe/London'); require_once 'phpExcel/PHPExcel/IOFactory.php'; require_once 'phpExcel/PHPExcel.php'; $inputFileName = 'doc/ModUnico'; $excel2 = PHPExcel_IOFactory::createReader('Excel2007'); $excel2 = $excel2->load($inputFileName.'.xlsx'); $excel2->setActiveSheetIndex(0); $excel2->getActiveSheet()->setCellValue('H5', '4'); $objWriter = PHPExcel_IOFactory::createWriter($excel2, 'Excel2007'); $objWriter->save($inputFileName.'_.xlsx');

Reading data (just 20000 numbers) from a xlsx file takes forever: import pandas as pd xlsxfile = pd.ExcelFile("myfile.xlsx") data = xlsxfile.parse('Sheet1', index_col = None, header = None) takes about 9 seconds. If I save the same file in csv format it takes ~25ms: import pandas as pd csvfile = "myfile.csv" data = pd.read_csv(csvfile, index_col = None, header = None) Is this an issue of openpyxl or am I missing something? Are there any alternatives? Matti John xlrd has support for .xlsx files, and this answer suggests that at least the beta version of xlrd with .xlsx support was quicker than

1、简介 Laravel Excel 在 Laravel 5 中集成 PHPOffice 套件中的 PHPExcel ，从而方便我们以优雅的、富有表现力的代码实现Excel/CSV文件的导入和 导出 。 该项目的GitHub地址是： https://github.com/Maatwebsite/Laravel-Excel。 2、安装&配置 使用Composer安装依赖 本文我们将在Laravel中使用Laravel Excel简单实现Excel文件的导入和导出。 首先进入Laravel项目根目录下使用Composer安装依赖： composer require maatwebsite/excel=~2.0 安装后的设置 在 config/app.php 中注册服务提供者到 providers 数组： Maatwebsite\Excel\ExcelServiceProvider::class, 同样在 config/app.php 中注册门面到 aliases 数组： 'Excel' => Maatwebsite\Excel\Facades\Excel::class, 如果想要对Laravel Excel进行更多的自定义配置，执行如下Artisan命令： php artisan vendor:publish 执行成功后会在 config 目录下生成一个配置文件 excel.php 。
