# Upgrading to 3.* from 2.1

Version 3.* is not backwards compatible with 2.*. It's not possible to provide a step-by-step migration guide as it's a complete paradigm shift.

New dependencies

3.* introduces some new dependencies.

  • Requires PHP 7.0 or higher.
  • Requires Laravel 5.5 (or higher).
  • Requires PhpSpreadsheet instead of PHPExcel.

Deprecations

ALL Laravel Excel 2.* methods are deprecated and will not be able to use in 3.0 .

  • Excel::load() is removed and replaced by Excel::import($yourImport)
  • Excel::create() is removed and replaced by Excel::download/Excel::store($yourExport)
  • Excel::create()->string('xlsx') is removed an replaced by Excel::raw($yourExport, Excel::XLSX)
  • 3.0 provides no convenience methods for styling, you are encouraged to use PhpSpreadsheets native methods.
