I want to create a preview of existing excel file(xlsm,xlsx) in browser. I using phpExcel to convert excel file to html file and after this take HTML code from it but after all this converters the tabs (worksheets) disappear and I cannot go to next one, how may I repair this?.
public function createHtmlPreview($path)
{
$file = preg_replace('/\\.[^.\\s]{3,4}$/', '', $path).'.htm';
$objPHPExcelReader = \PHPExcel_IOFactory::createReader('Excel2007');
$objPHPExcel = $objPHPExcelReader->load($path);
$objPHPExcelWriter = \PHPExcel_IOFactory::createWriter($objPHPExcel,'HTML');
$objPHPExcel = $objPHPExcelWriter->save($file);
$html = new \DOMDocument();
$html->loadHTMLFile($file);
unlink($file);
return $html->saveHTML();
//return $file;
}

I'm using PhpSpreadSheet and I need to save the sheets contained in a workbook as individual CSV files.
I've tried to use $reader->setLoadAllSheets(); but at the end I always have a single CSV file containing the first sheet of the workbook.
Here's an example of my code:
$excel = 'excelfile.xlsx';
$name = 'newCsvName';
//Read the file
$reader = new Xlsx();
$reader->setReadDataOnly(true);
$reader->setLoadAllSheets();
$spreadsheet = $reader->load($excel);
//Write the CSV file
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Csv($spreadsheet);
$writer->setDelimiter(";");
$csvPath = 'csv_files/' . $dir . '/' . $name .'.csv';
$writer->save($csvPath);
This is how I solved it.
I first load every sheet contained into the excel file and then save a new CSV file with the info. I'm sure there should be a better way, but it works fine.
$excel = 'excelfile.xlsx';
$name = 'newCsvName';
$reader = new Xlsx();
$reader->setReadDataOnly(true);
//Get all sheets in file
$sheets = $reader->listWorksheetNames($excel);
//Loop for each sheet and save an individual file
foreach($sheets as $sheet){
//Load the file
$spreadsheet = $reader->load($excel);
//Write the CSV file
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Csv($spreadsheet);
$writer->setDelimiter(";");
$csvPath = 'csv_files/' . $dir . '/' . $name.'_'.$sheet.'.csv';
$writer->save($csvPath);
}
The answer above is missing a vital line:
$reader->setLoadSheetsOnly([$sheet]);
This makes the reader load the specific sheet which then allows the loop to open the specific sheet and write it to the CSV, otherwise you will find this code creates each sheet name but with the contents from the first sheet of the document.
$excel = 'excelfile.xlsx';
$name = 'newCsvName';
$reader = new Xlsx();
$reader->setReadDataOnly(true);
//Get all sheets in file
$sheets = $reader->listWorksheetNames($excel);
//Loop for each sheet and save an individual file
foreach($sheets as $sheet){
//Load the file
$reader->setLoadSheetsOnly([$sheet]);
$spreadsheet = $reader->load($excel);
//Write the CSV file
$writer = new \PhpOffice\PhpSpreadsheet\Writer\Csv($spreadsheet);
$writer->setDelimiter(";");
$csvPath = 'csv_files/' . $dir . '/' . $name.'_'.$sheet.'.csv';
$writer->save($csvPath);
}
I am creating excel file with single worksheet using PHPExcel.
I have managed to do this but the issue came after when I created it ones then it didn't get clear so when I am creating it again the the previous data came along with the new data.
So I am just want to clear the excel file before using it again.
Here is the code:
require_once APPPATH.'third_party/PHPExcel.php';
require_once APPPATH.'third_party/PHPExcel/IOFactory.php';
//Getting Data form database
$bTob_gstdata = $this->reports_model->get_bTob_gstdata($date_from, $date_to);
//Sample Excel File (which is clear already Just contain the structure)
$filename = 'assets/btob_base_excel.xls';
$objPHPExcel = PHPExcel_IOFactory::load($filename);
echo $filetype = PHPExcel_IOFactory::identify($filename);
$excel2 = PHPExcel_IOFactory::createReader($filetype);
$excel2 = $excel2->load('assets/btob_base_excel.xls'); // Empty Sheet
$excel2->setActiveSheetIndex(0);
$t=0;
$total_invoice_count = 0;
$recipients_count = array();
$invoice_count = array();
for($k=5;$k<(count($bTob_gstdata)+5);$k++)
{
//Adding Data in Excel WorkSheet
$excel2->getActiveSheet()
->setCellValue('A'.$k, $bTob_gstdata[$t]["dist_gstin"]);
$t++;
}
$excel2->getActiveSheet()->setCellValue('A3', (count($recipients_count)));
$excel2->getActiveSheet()->setCellValue('B3', (count($invoice_count)));
$excel2->getActiveSheet()->setCellValue('D3', '=SUM(D5:D'.(count($bTob_gstdata)+5).')');
$excel2->getActiveSheet()->setCellValue('J3', '=SUM(J5:J'.(count($bTob_gstdata)+5).')');
$excel2->setActiveSheetIndex(0);
$objWriter = PHPExcel_IOFactory::createWriter($excel2, $filetype);
$objWriter->save('btocl_gst_report.xls'); //Saving the excel file
header("location:".base_url("btob_gst_report.xls")); // Downloading the excel file
I want to clear the created excel file to Reuse
I already have a document of excel and I want to use php to insert an image to that excel.
Is it possible to do that? How to implement it (code)?
Thanks,
$fileType = 'Excel2007';
$fileName = 'test.xlsx';
// Load the workbook
$objPHPExcelReader = PHPExcel_IOFactory::createReader($fileType);
$objPHPExcel = $objPHPExcelReader->load($fileName);
// Add an image to the worksheet
$objDrawing = new PHPExcel_Worksheet_Drawing();
$objDrawing->setName('My Image');
$objDrawing->setDescription('The Image that I am inserting');
$objDrawing->setPath('./images/myImage.png');
$objDrawing->setCoordinates('B2');
$objDrawing->setWorksheet($objPHPExcel->getActiveSheet());
// Save the workbook
$objPHPExcelWriter = PHPExcel_IOFactory::createWriter($objPHPExcel,$fileType);
$objPHPExcelWriter->save($fileName);
I have the Excel file that contains a few sheets. How to split this file to get get each sheet as a separate file?
From PHP, you'llneed to have something like phpExcel to open the spreadsheet, and rewrite each tab as a new file.
Using the PHPExcel library:
include 'PHPExcel.php';
$fileType = 'Excel2007';
$inputFileName = 'testExcel.xlsx';
$objPHPExcelReader = PHPExcel_IOFactory::createReader($fileType);
$objPHPExcel = $objPHPExcelReader->load($inputFileName);
$sheetIndex = 0;
$sheetCount = $objPHPExcel->getSheetCount();
while ($sheetIndex < $sheetCount) {
++$sheetIndex;
$workSheet = $objPHPExcel->getSheet(0);
$newObjPHPExcel = new PHPExcel();
$newObjPHPExcel->removeSheetByIndex(0);
$newObjPHPExcel->addExternalSheet($workSheet);
$objPHPExcelWriter = PHPExcel_IOFactory::createWriter($newObjPHPExcel,$fileType);
$outputFileTemp = explode('.',$inputFileName);
$outputFileName = $outputFileTemp[0].$sheetIndex.'.'.$outputFileTemp[1];
$objPHPExcelWriter->save($outputFileName);
}
I have an excel spreadsheet with images which i need to upload to a db. How do i parse the spreadsheet into an array?
http://code.google.com/p/php-excel-reader/ should be able to handle most of what you need.
I'd recommend PHPExcel for parsing Excel files (though I am biased, as one of the developers). You don't mention which version of Excel (xls or xlsx files), but PHPExcel can read either... and it can read the images.
Reading the Excel worksheet data into a PHP array can be as simple as:
$inputFileName = './sampleData/example1.xls';
$objPHPExcel = PHPExcel_IOFactory::load($inputFileName);
$sheetData = $objPHPExcel->getActiveSheet()->toArray();
var_dump($sheetData);
EDIT
To extract images, use something like:
$objPHPExcel = PHPExcel_IOFactory::load("MyExcelFile.xls");
foreach ($objPHPExcel->getSheetByName("My Sheet")->getDrawingCollection() as $drawing) {
if ($drawing instanceof PHPExcel_Worksheet_MemoryDrawing) {
ob_start();
call_user_func(
$drawing->getRenderingFunction(),
$drawing->getImageResource()
);
$imageContents = ob_get_contents();
ob_end_clean();
}
}
