Here are the steps to generate Excel in the CodeIgniter 3 application with PhpSpreadsheet:

Step 1: Download and install CodeIgniter.

Step 2: Run below composer command to download phpspreadsheet library from your project folder. It will create a new folder called “vendor” and it will download phpoffice/phpspreadsheet library into it.

$ composer require phpoffice/phpspreadsheet

Here is my the directory structure after installing phpoffice/phpspreadsheet

Step 3: Open application/config/config.php file and set you vendor directory path

 $config['composer_autoload'] = 'vendor/autoload.php';

Step 4: Use phpspreadsheet library inside in your controller, here is the sample:

		$sheet->setCellValue('A1', 'Hello World !');
		$writer = new Xlsx($spreadsheet);

		$filename = 'name-of-the-generated-file.xlsx';

		$writer->save($filename); // will create and save the file in the root of the project


	public function download()
		$spreadsheet = new Spreadsheet();
		$sheet = $spreadsheet->getActiveSheet();
		$sheet->setCellValue('A1', 'Hello World !');
		$writer = new Xlsx($spreadsheet);

		$filename = 'name-of-the-generated-file';

		header('Content-Type: application/');
		header('Content-Disposition: attachment;filename="'. $filename .'.xlsx"'); 
		header('Cache-Control: max-age=0');
