Laravel-excel: 如何合并两个 xlsx 文件并下载合并的文件？

嗨@kurianic ，下面的示例将读取工作簿 A 和 B 中的所有工作表，并将它们复制到新工作簿 C。请确保 A 和 B 不包含同名工作表。

// Load the workbooks to merge in a collection.
// This example is assuming they're stored in the Laravel storage folder.
$workbooks = collect([
    'workbookA.xlsx',
    'workbookB.xlsx',
])->map(function ($filename) {
    return Excel::load(storage_path($filename));
});

// Create merged workbook
$workbookC = Excel::create('workbookC', function ($excel) use ($workbooks) {
    // For each workbook to be merged
    $workbooks->each(function ($workbook) use ($excel) {
        // Get all the sheets
        collect($workbook->getAllSheets())->each(function ($sheet) use ($excel) {
            // And add them to the merged workbook
            $excel->addExternalSheet($sheet);
        });
    });
})->save(); // save merged workbook to storage/exports/workbookC.xlsx

嗨@stephanecoinon ，我想多次添加相同的工作表，以防止名称重复，我调用了 $sheet->setTitle。 但它给了我一个错误“工作表不存在”。 在 setTitle 之后调用 addExternalSheet 时。

$sheet_original->setTitle("SHEET ".$i); $sheets[$i] = $sheet_original; $sheets[$i]->cell('I64', function($cell) use($i) { $cell->setValue($i); }); $excel->addExternalSheet($sheets[$i] );

@sarpkaya-xx 试试addSheet() ：

    Excel::create('workbook', function ($excel) {
        // Create first "original" sheet
        $original = $excel->sheet('Sheet 1', function ($sheet) {
            $sheet->fromArray([
                ['foo' => 'bar']
            ]);
        });
        // Copy the first sheet 4 times
        for ($sheetCount = 2; $sheetCount <= 5; $sheetCount++) {
            $copy = $original->getSheet()->copy();
            $copy->setTitle("Sheet {$sheetCount}");
            $excel->addSheet($copy);
        }
    })->save();
