Call to undefined method Maatwebsite\Excel\Excel::load()

I'm trying to import excel file (.xlsx) using maatwebsite 3.0. How to fix This error

Call to undefined method Maatwebsite\Excel\Excel::load()

My controller

public function importsave(Request $request)
{
   if($request->hasFile('excel'))
    {
        $path = $request->file('excel')->getRealPath();
        $data= Excel::load($path, function($reader) {})->get();
        if(!empty($data) && $data->count())
        {
            foreach($data->toArray() as $key=>$value)
            {
                if(!empty($value))
                {
                    Employee::insert($value);
                }
            }
        }
    }
}

Version 3.0 of that package doesn't handle imports yet. Release date for this feature is unknown. See this post for more details: https://medium.com/@maatwebsite/laravel-excel-lessons-learned-7fee2812551

I suggest you switch to version 2.*.

Else you want to continue further 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.
