Here i am sharing how one can generate Excel file using php library "PhpSpreadsheet". To use library you need to install using composer. Open command window and excecute below command in your project folder:
composer require phpoffice/phpspreadsheet
It will create a new folder as "vendor" in your project and copy all files and folders as below:
Next create a file as "sample.php" and copy below code:
<?php require 'vendor/autoload.php'; use PhpOffice\PhpSpreadsheet\Spreadsheet; use PhpOffice\PhpSpreadsheet\Writer\Xlsx; $spreadsheet = new Spreadsheet(); $sheet = $spreadsheet->getActiveSheet(); $sheet->setCellValue('A1', 'Hello World !'); $writer = new Xlsx($spreadsheet); $writer->save('hello world.xlsx');
Now open your browser and open the file "sample.php" it will create a excel file as "hellow world.xlsx" in same folder.
