How to modifiy/set encoding

[OvalMedia]

I am importing csv files that are encoded in ISO-8859-15 which results in cryptic chars instead of umlauts (ä, ö, ü). Is there a way to set or even detect the expected encoding of a file? It all works fine when I convert the csv to utf-8 beforehand but that's a manual step I would like to avoid.

Thanks

It works when I set the input_encoding to ISO-8859-15 in the config/excel.php but it would still be nice to decide the encoding on a per file basis.

For reference, you can override the call method and update the import settings there

use Maatwebsite\Excel\Concerns\WithCustomCsvSettings;

class MyImportFile extends ImportAction
{
    // override the call method
    public function call(array $parameters = []): mixed
    {
        // save the current import config so we can revert later
        $cfg = config('excel.imports.csv');

        // update the import config with this importer settings
        config(['excel.imports.csv' => array_merge($cfg, $this->getCsvSettings())]);

        // call the import process
        $ret = parent::call($parameters);

        // revert back to the default config
        config(['excel.imports.csv' => $cfg]);

        return $ret;
    }

    protected function getCsvSettings(): array
    {
        // for example:
        return [
            'input_encoding' => 'ISO-8859-15',
            'delimiter' => ';',
        ];
    }
}
