PHPexcel save to CSV linked cells to another sheet are empty - csv

Question

Could someone help me?
I have xlsx file, with 2 sheets.
Second sheet contain cells linked to another(first) sheet.
When I save sheet to CSV file:
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV');
This function doesn't save (linked) cells value...
My code looking like this:
$objPHPExcel = new PHPExcel();
// Read your Excel workbook
try
{
$inputFileType = PHPExcel_IOFactory::identify($excelFile);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objReader->setLoadSheetsOnly('list');
$objReader->setLoadSheetsOnly('main');
/* I also tried like this:
$worksheetList = $objReader->listWorksheetNames($excelFile);
$sheetname = $worksheetList[0];
$sheetname2 = $worksheetList[1];
$objReader->setLoadSheetsOnly($worksheetList[0]);
$objReader->setLoadSheetsOnly($sheetname);
*/
$objPHPExcel = $objReader->load($excelFile);
}
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'CSV');
$objWriter->save($filename);
I also tried to save to EXCEL files (xls and xlsx) -> the same problem, the cells (which was linked) they are empty...
My linked cells looked like this: "=list!C46"
Many hours of looking for answer, I have found not good solution:
I've removed any of these lines: $objReader->setLoadSheetsOnly('list');
and add:
$activeSheetData = $objPHPExcel->getActiveSheet()->toArray(null, true, true, true);
$objPHPExcel->getActiveSheet()->fromArray($activeSheetData, false);
just after:
$objPHPExcel = $objReader->load($excelFile);
and also add: $objWriter->setSheetIndex(1);
Now it will works, but with problems...
One column in original format have linked cells like this: "=list!$AV$46"
I mean with $ symbol.
More detailed:
If I have: $objReader->setReadDataOnly(true);
and have those cells: "=list!$AV$46" then they are empty in output.
But if I remove: $objReader->setReadDataOnly(true);
then those cells: "=list!$AV$46" works good and have a value, but with format
like: 11/17/2017.
As I removed $objReader->setReadDataOnly(true);, then I can't apply
this my code:
$objPHPExcel->setActiveSheetIndex(1)->getStyle('AV1:AV'.$highestRow)->getNumberFormat()->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_DATE_YYYYMMDD);
Then second question, how to write new date format?
I also wanted to say, that initial date format was:
17.11.2017.
And I wanted 17-11-17 (FORMAT_DATE_YYYYMMDD).
And again, with cells which looks like "=list!AV46" all works good.
UPDATE: Solvation: $objReader->setLoadSheetsOnly(['list', 'main']); + $objPHPExcel->setActiveSheetIndex(1); before any of: $objPHPExcel->getActiveSheet()->...

Here's your first problem
$objReader->setLoadSheetsOnly('list');
$objReader->setLoadSheetsOnly('main');
You're only ever loading one sheet, the last one that you tell PHPExcel to load, which is main. Multiple calls to setLoadSheetsOnly() overwrite the setting of the previous call.
If you want to load both sheets, then you need to pass an array listing all the sheetnames that you want to load
$objReader->setLoadSheetsOnly(['list', 'main']);
This is explained in the PHPExcel Documentation
The documentation also says not to use $objReader->setReadDataOnly(true); unless you understand what it is doing; it tells PHPExcel to load only the rw data, not the formatting of data; and it is the formatting that differentiates a number from a date in Excel.
