                 $data[] = array(
                    $product->date_start,
                    $product->date_end,
                    $product->condition_status,

                    $product->nama_companies,
                );

            $sheet->fromArray($data);
        });
    })->export('xls');
    }

and it should be :

my problem is how to change the number into text what i want in the header table.

what improvements do i have to make to the code to achieve my goal?

NB : i use maatwebsite/excel

From the official docs:

By default the export will use the keys of your array (or model attribute names) as first row (header column). To change this behaviour you can edit the default config setting (excel::export.generate_heading_by_indices) or pass false as 5th parameter:

Change:

$sheet->fromArray($data); to $sheet->fromArray($data, null, 'A1', false, false);

how to change the number into text what i want in the header table.

Then you can define your own heading and prepend it to the first row of the sheet.

$headings = array('date start', 'date end', 'status condition', 'security', 'company');

$sheet->prependRow(1, $headings);

That should make it work.
