use ToCollection method the wrap everything within if($row->filter()->isNotEmpty())
```
public function collection(Collection $rows)
{
foreach($rows as $row) {
if($row->filter()->isNotEmpty()){
// you logic can go here

            $user = User::create([
                'name' => ucwords($row['name']),
                'class' => $row['class'],
                ...
            ]);
        }
    }   
}

```

How does it work for the toModel way?

[patrickbrouwers]

You can return null in toModel, will skip those rows.

Hello,
I have tried to use $row->filter()->isNotEmpty() but due to the fact that I use WithValidation the codes stops with an validation error. My rules look like this:

public function rules(): array { return [ 'name' => 'required', '*.name' => 'required', 'email' => 'required|email', '*.email' => 'required|email', 'discount' => 'nullable|numeric', '*.discount' => 'nullable|numeric', ]; }

Unfortunately, if you have an excel file an delete the content of some rows at the end of the excel file Laravel-Excel still recognizes them as not empty. Then the validation fails. I want to skip such rows before validation.

@seven21 , did you find a solution for this ? does anyone got resolved this issue ?

[seven21]

I use a workaround which helps in my case. Validation is extended by nullable on all rows to avoid errors and then In the method I have added
public function model(array $row) {if(!array_filter($row)) { return null;} return new Customer([..... and skip these rows at this point. Not really happy with this as I cannot return an useful error message but as I found no solution the best way to get the code running.

[mohamednizar]

@seven21 Thank you very much for your instance and useful message, But I'm also thinking this isn't a good way if we actually using validations.

@mohamednizar how did you resolve this issue?

[mohamednizar]

I didn't completely resolve the issue, but for my solution I added following custom functions to return the batch size and row limit. the row limit only will be count if data exists in the column.

 public function limit(): int {
        $highestColumn = $this->worksheet->getHighestDataColumn(3);
        $higestRow = 0;
        for ($row = $this->startRow(); $row <= $this->highestRow; $row++) {
            $rowData = $this->worksheet->rangeToArray('A' . $row . ':' . $highestColumn . $row, NULL, TRUE, FALSE);
            if (isEmptyRow(reset($rowData))) {
                continue;
            } else {
                $higestRow += 1;
            }
        }
        return $higestRow;
    }

   public function batchSize(): int {
        $highestColumn = $this->worksheet->getHighestDataColumn(3);
        $higestRow = 1;
        for ($row = $this->startRow(); $row <= $this->highestRow; $row++) {
            $rowData = $this->worksheet->rangeToArray('A' . $row . ':' . $highestColumn . $row, NULL, TRUE, FALSE);
            if (isEmptyRow(reset($rowData))) {
                continue;
            } else {
                $higestRow += 1;
            }
        }
        if ($higestRow == 0) {
            exit;
        } else {
            return $higestRow;
        }
    }

Some time this may help you to resolve some sort of problems.

you can ignore the empty row by updating the config/excel.php file.

from:

        /*
        |--------------------------------------------------------------------------
        | Ignore Empty
        |--------------------------------------------------------------------------
        |
        | When dealing with imports, you might be interested in ignoring
        | rows that have null values or empty strings. By default rows
        | containing empty strings or empty values are not ignored but can be
        | ignored by enabling the setting ignore_empty to true.
        |
        */
        'ignore_empty' => false,

to:

        /*
        |--------------------------------------------------------------------------
        | Ignore Empty
        |--------------------------------------------------------------------------
        |
        | When dealing with imports, you might be interested in ignoring

        | containing empty strings or empty values are not ignored but can be

        |
        */
        'ignore_empty' => true,
