When dealing with big files, it's better to import the data in big chunks. You can enable this with filter('chunk');To import it into chunks you can use chunk($size, $callback) instead of the normal get(). The first parameter is the size of the chunk. The second parameter is a closure which will return the results.
Excel::filter('chunk')->load('file.csv')->chunk(250, function($results){ foreach($results as $row) { // do stuff }});
When working with ExcelFile injections (in the constructor or as method injection), you can enable the chunk filter inside the ExcelFile class
class UserListImport extends \Maatwebsite\Excel\Files\ExcelFile { public function getFile() { return 'file.csv'; } public function getFilters() { return [ 'chunk' ]; }}
public function importUserList(UserListImport $import){ $import->chunk(250, function($results) { // do stuff // or return true if you want to stop importing. });}
# Queued chunks
We automatically queue every chunk for you, if you have enabled the queue driver in your config.
If you want to by-pass the behaviour, you can pass false as the third parameter of chunk($size, $callback, $shouldQueue).
A non-default job queue may be specified by passing its name as the third parameter of chunk($size, $callback, $shouldQueue).

You basically load the data into what Excel calls a Data Model, keeping just a link to the original CSV file. After that, you can create a Pivot Table directly from the Data Model. With that method, you will be able to load millions of rows.
If you have worksheets with data that you're not using—and that don't contain any formulas you're using—delete them from the spreadsheet. The more data points you have in your workbook, the larger your file size will be. Removing unused data will reduce your file size.
