This article will introduce to you how to use PhpSpreadsheet to import and export Excel. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.
Recently, the company has to do reporting functions, including various financial statements, salary reports, attendance reports, etc. The complexity is so great There are so many people, so I specially encapsulate the import & export operations suitable for various major scenes. I hope that the masters from all walks of life will pay attention to the shortcomings so that I can continue to improve.
Since PHPExcel has stopped updating and maintaining, phpspreadsheet is supported. Students who don’t know how to pull the project package through composer can check out the article Learning Composer. Introduction method:
composer require phpoffice/phpspreadsheet
Since my project requires various operations such as centering, background, cell format, etc., I introduce a lot of them. When you use it, you can use it according to your actual situation. Need to be introduced.
use PhpOffice\PhpSpreadsheet\Reader\Xlsx;use PhpOffice\PhpSpreadsheet\Reader\Xls;use PhpOffice\PhpSpreadsheet\IOFactory;use PhpOffice\PhpSpreadsheet\Cell\Coordinate;use PhpOffice\PhpSpreadsheet\Spreadsheet;use PhpOffice\PhpSpreadsheet\Worksheet\PageSetup;use PhpOffice\PhpSpreadsheet\Cell\DataType;use PhpOffice\PhpSpreadsheet\Style\Fill;use PhpOffice\PhpSpreadsheet\Style\Color;use PhpOffice\PhpSpreadsheet\Style\Alignment;use PhpOffice\PhpSpreadsheet\Style\Border;use PhpOffice\PhpSpreadsheet\Style\NumberFormat;
In addition to simply processing Excel data, you can also extract merged items, formula items, and cell formats in Excel. After extraction, you can according to business needs After corresponding processing, it is stored for subsequent operations.

After the data is processed, the exported Excel can be configured in various ways through additional configurations, such as print style, locked rows, background color, width, etc.
