Merge in excel with phpSpreadSheet - php

Question

I want to merge 2 or more excel with PhpSpreadsheet. I'm trying to keep the styles for each sheet, this is my code:
<?php
require 'vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
$inputFileType = 'Xlsx';
$inputFileNames = [
'a.xlsx',
'b.xlsx',
'c.xlsx'
];
$sheetnames = [
'Worksheet',
'Worksheet1',
'Worksheet2'
];
$reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader($inputFileType);
$reader->setLoadSheetsOnly($sheetnames);
$inputFileName = array_shift($inputFileNames);
$spreadsheetMain = $reader->load($inputFileName);
$spreadsheetMain->getActiveSheet()->setTitle('page0');
$contador = 1;
foreach ($inputFileNames as $book => $inputFileName) {
echo ('$inputFileName: ' . $inputFileName) . '</br>';
$spreadsheet = $reader->load($inputFileName);
$clonedWorksheet = clone $spreadsheet->getActiveSheet()->setTitle($inputFileName[0]);
$clonedWorksheet->setTitle('page' . $contador);
$spreadsheetMain->addSheet($clonedWorksheet);
$contador++;
}
$writer = new Xlsx($spreadsheetMain);
$writer->save('prueba1.xlsx');
to do what I want, I need to change this
$spreadsheetMain->addSheet($clonedWorksheet);
for that $spreadsheetMain->addExternalSheet($clonedWorksheet);
But when I execute that code I get the error: 'Sheet does not exist'
I tought it's not still implemented, but is here in the documentation page: https://phpspreadsheet.readthedocs.io/en/develop/topics/worksheets/#copying-worksheets
Here you can download my excels and code for try if you want:

Answer 1

The problem with addExternalSheet was that I needed to name both sheets (the original that I load and the cloned Sheet) with the same name. (All files are here : https://drive.google.com/open?id=1qkI8jdYDuA6e5CW6z3k0r_7j1pTvW_6D, mergeSolved is the correct file) This is the code with the solution:
require 'vendor/autoload.php';
use PhpOffice\PhpSpreadsheet\Writer\Xlsx;
$inputFileType = 'Xlsx';
$inputFileNames = [
'a.xlsx',
'b.xlsx',
'c.xlsx'
];
$sheetnames = [
'Worksheet',
'Worksheet1',
'Worksheet2'
];
$reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader($inputFileType);
$reader->setLoadSheetsOnly($sheetnames);
$inputFileName = array_shift($inputFileNames);
$spreadsheetMain = $reader->load($inputFileName);
$spreadsheetMain->getActiveSheet()->setTitle('page0');
$contador = 1;
foreach ($inputFileNames as $book => $inputFileName) {
echo ('$inputFileName: ' . $inputFileName) . '</br>';
$spreadsheet = $reader->load($inputFileName);
$clonedWorksheet = clone $spreadsheet->getSheetByName('Worksheet'.$contador);
$clonedWorksheet->setTitle('Worksheet'.$contador);
$spreadsheetMain->addExternalSheet($clonedWorksheet);
$contador++;
}
$writer = new Xlsx($spreadsheetMain);
$writer->save('prueba1.xlsx');`

Answer 2

require 'vendor/autoload.php';
$lists = [
'flie_01.xlsx',
'flie_02.xlsx'
];
$outfile='/tmp/merge.xlsx';
$merge_spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();
$merge_spreadsheet->getProperties()->setCreator("act");
foreach($lists as $file){
if(!file_exists($file)){
continue;
}
$reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader("Xlsx");
$reader->setReadDataOnly(true);
$spreadsheet = $reader->load($file);
foreach($spreadsheet->getSheetNames() as $sheet_name ){
$clonedWorksheet = clone $spreadsheet->getSheetByName($sheet_name);
$clonedWorksheet->setTitle($sheet_name);
$merge_spreadsheet->addSheet($clonedWorksheet);
}
}
$merge_spreadsheet->removeSheetByIndex(0);
$writer = \PhpOffice\PhpSpreadsheet\IOFactory::createWriter($spreadsheet,'Xlsx');
$writer->save($outfile);
