Laravel-excel: Downloading a collection as Excel

[courtney1403]

Hello, my question is just basic, but because I couldn't find the answer anywhere, so please help me!
I tried to use this one:

(new Collection([[1, 2, 3], [1, 2, 3]]))->downloadExcel(
$filePath,
$writerType = null,
$headings = false
)

I don't know what correct form should $writeType be. I tried Excel::XLSX but got the error:
"Undefined class constant 'XLSX'".

Hope you don't mind such a basic question, and thank you very much!

@courtney1403 you can let the package guess the correct writer type. Just have .xlsx as your file extension in the filePath.

Excel::XLSX is \Maatwebsite\Excel\Excel::XLSX
