Welcome to PhpSpreadsheet's documentation

PhpSpreadsheet is a library written in pure PHP and offers a set of classes that allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc.

PHP version 7.4 or newer to develop using PhpSpreadsheet. Other requirements, such as PHP extensions, are enforced by composer. See the require section of the composer.json file for details.

LTS: Support for PHP versions will only be maintained for a period of six months beyond the end of life of that PHP version.

Currently the required PHP minimum version is PHP 7.4: the last release was 7.4.32 on 29th September 2022, and security support ends on 28th November 2022, so PhpSpreadsheet will support PHP 7.4 until 28th May 2023. PHP 8.0 is officially End of Life on 26th November 2023, and PhpSpreadsheet will continue to support PHP 8.0 for six months after that date.

See the composer.json for other requirements.

to ensure that the correct dependencies are retrieved to match your deployment environment.

See CLI vs Application run-time for more details.
