I use PHPspreadsheet to covert a xlsx file to a csv file.
In column "I" I have dates and times like [26-04-2019 07:57:35] how can I change this to [2019-04-26 07:57:35]?
I want to change this for uploading to MYSQL.
use \PhpOffice\PhpSpreadsheet\Reader\Xlsx;
use \PhpOffice\PhpSpreadsheet\Writer\Csv;
$xls_file = "$file";
$reader = new Xlsx();
$spreadsheet = $reader->load($xls_file);
$loadedSheetNames = $spreadsheet->getSheetNames();
$writer = new Csv($spreadsheet);
foreach($loadedSheetNames as $sheetIndex => $loadedSheetName) {
$writer->setSheetIndex($sheetIndex);
$writer->save($loadedSheetName.'.csv');
}
You will need to loop through each row of each sheet and change column I to the format needed for MySQL.
foreach($loadedSheetNames as $sheetIndex => $loadedSheetName) {
$writer->setSheetIndex($sheetIndex);
$worksheet = $spreadsheet->getActiveSheet();
$highestRow = $worksheet->getHighestRow(); // e.g. 10
for ($row = 1; $row <= $highestRow; ++$row) {
$datenow = $worksheet->getCellByColumnAndRow(9,$row)->getValue();
$worksheet->setCellValue('I' . $row,date('Y-m-d h:i:s',strtotime($datenow)));
} // end of for loop through the sheet
$writer->save($loadedSheetName.'.csv');
}

I am trying to import a grade sheet into mysql database but that excel file have multiple sheet how can i make it so only a specified sheet will be going into my database
$uploadfile=$_FILES['uploadfile']['tmp_name'];
require 'PHPExcel/Classes/PHPExcel.php';
require_once 'PHPExcel/Classes/PHPExcel/IOFactory.php';
$objExcel =PHPExcel_IOFactory::load($uploadfile);
foreach($objExcel->getWorksheetIterator() as $worksheet)
{
$highestrow=$worksheet->getHighestRow();
for($row=8;$row<=$highestrow;$row++){
$name=$worksheet->getCellByColumnAndRow(1,$row)->getValue();
$finalgrade=$worksheet->getCellByColumnAndRow(15,$row)->getValue();
if($finalgrade != ''){
$insertqry = "INSERT INTO `user`(`stud_name`, `final_grade`) VALUES ('$name',' $finalgrade')";
$insertres = mysqli_query($con,$insertqry);
}
}
}
As far as I understand you are looking to get data from a specific sheet.
In PHPExcel there is this function: setActiveSheetIndex(sheet_index)
You can try like this:
$uploadfile = 'test.xlsx';
$objExcel = PHPExcel_IOFactory::load($uploadfile);
$objData = PHPExcel_IOFactory::createReader('Excel2007');
//read only
$objData->setReadDataOnly(true);
$objPHPExcel = $objData->load($uploadfile);
// Select sheet to get
$sheet = $objPHPExcel->setActiveSheetIndex(1);
$Totalrow = $sheet->getHighestRow();
$LastColumn = $sheet->getHighestColumn();
$TotalCol = PHPExcel_Cell::columnIndexFromString($LastColumn);
$data = [];
// Proceed to loop through each data cell
// Repeat rows, Since the first row is assumed to be the column header, we will loop the value from line 2
for ($i = 2; $i <= $Totalrow; $i++) {
//---- Loop column
for ($j = 0; $j < $TotalCol; $j++) {
// Proceed to get the value of each cell into the array
$data[$i - 2][$j] = $sheet->getCellByColumnAndRow($j, $i)->getValue();;
}
}
var_dump($data);
i just deleted the foreach and add getSheetName()
require 'PHPExcel/Classes/PHPExcel.php';
require_once 'PHPExcel/Classes/PHPExcel/IOFactory.php';
$objExcel =PHPExcel_IOFactory::load($uploadfile);
$worksheet = $objExcel->getSheetByName('GEN.AVERAGE');
$highestrow=$worksheet->getHighestRow();
for($row=8;$row<=$highestrow;$row++){
$name=$worksheet->getCellByColumnAndRow(1,$row)->getValue();
$finalgrade=$worksheet->getCellByColumnAndRow(15,$row)->getValue();
if($finalgrade != ''){
$insertqry = "INSERT INTO `user`(`stud_name`, `final_grade`) VALUES ('$name',' $finalgrade')";
$insertres = mysqli_query($con,$insertqry);
}
}
I am just learning to code, i dont know much yet.

here's my code. I need to output the data in json from excel table. I have been searching for solution in youtube and google, but i have found nothing i understand so far. What should i write, what should i do? Also, i got this code from this forum and i edited it so it works for me. I would be very grateful if someone could help me with this <3
Try something like this, using your loop to create an array and the json_encode to convert it to a json string:
<!doctype>
<html>
<head>
</head>
<body>
<?php
require_once "Classes/PHPExcel.php";
$tmpfname = "tabula1.xlsx";
$excelReader = PHPExcel_IOFactory::createReaderForFile($tmpfname);
$excelObj = $excelReader->load($tmpfname);
$worksheet = $excelObj->getSheet(0);//
$lastRow = $worksheet->getHighestRow();
$data = [];
for ($row = 1; $row <= $lastRow; $row++) {
$data[] = [
'A' => $worksheet->getCell('A'.$row)->getValue(),
'B' => $worksheet->getCell('B'.$row)->getValue()
];
}
echo json_encode($data);
</body>
</html>
Only logic not tested
$result=array();
for ($row = 1; $row <= $lastRow; $row++)
{
array_push($result,array($worksheet->getCell('A'.$row)->getValue(),$worksheet->getCell('B'.$row)->getValue()));
}
echo json_encode($result);

I am trying to parse an Excel file. I am able to get the contents of individual cells of the excel. I am unable to add the data I got from the cell into an array.
function parseExcel($inputFileName){
$mh = new MainHandler;
// Read your Excel workbook
try {
$inputFileType = PHPExcel_IOFactory::identify($inputFileName);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFileName);
}catch(Exception $e) {
die('Error loading file "'.pathinfo($inputFileName,PATHINFO_BASENAME).'": '.$e->getMessage());
}
$Arr = array();
// Get worksheet dimensions
$sheet = $objPHPExcel->getActiveSheet();
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
for ($row = 1; $row <= $highestRow; $row++){
$myArray = array();
for($col = 'A' ; $col <= $highestColumn ; $col++){
$a = $sheet->getCell($col.$row);
// echo "\n".$a;
$myArray[] = $a;
}
// $Arr[] = $myArray;
echo json_encode($myArray);
}
// echo json_encode($Arr);
}
The output i get is
[{},{},{},{},{}][{},{},{},{},{}][{},{},{},{},{}]
What should be done to get the populated array as output?
What would be the most efficient way of checking data contained in arrays
I want to validate in the following ways:
if cell a and b are a string
if cell c and d are numbers
if cells are empty
Then how would it be best to catch errors and display them to the user?
I'm using codeigniter and the PHPExcel library
an example of where I'm currently at
public function read_excel()
{
$this->load->library('excel');
$inputFileName = 'test.xlsx';
/** Identify the type of $inputFileName **/
$inputFileType = PHPExcel_IOFactory::identify($inputFileName);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
/** Advise the Reader that we only want to load cell data **/
$objReader->setReadDataOnly(true);
/** Load $inputFileName to a PHPExcel Object **/
$objPHPExcel = $objReader->load($inputFileName);
$sheet = $objPHPExcel->getSheet(0);
$highestRow = $sheet->getHighestRow();
$highestColumn = $sheet->getHighestColumn();
// Loop through each row of the worksheet
for ($row = 2; $row <= $highestRow; $row++){ // Read a row of data into an array
$rowData = $sheet->rangeToArray('A'.$row.':'.$highestColumn.$row,NULL,TRUE,FALSE);
$cella = strtoupper($rowData[0][0]);
$cellb = strtoupper($rowData[0][1]);
$cellc = $rowData[0][2];
$celld = $rowData[0][3];
}
}
To Answer my own question i eventually went with the below
if (!isset($rowData[0][0],$rowData[0][1],$rowData[0][2])) {
echo "error cells a-c are required.";
}
for ($i=0; $i <$columns ; $i++) {
switch ($rowData[0][$i]) {
case (is_numeric($rowData[0][$i])):
filter_var($rowData[0][$i],FILTER_SANITIZE_NUMBER_INT);
echo $rowData[0][$i];
echo "</br>";
break;
case (is_string($rowData[0][$i])):
$rowData[0][$i] = preg_replace("/[^A-Za-z0-9\-]/"," ",$rowData[0][$i]);
break;
}
}
I'm looking for a way to do the following:
$file = 'file.xls';
$input = '<tr><td>Some input</td></tr>';
if (!file_exists($file))
{
create_excel($file); //Create the sheet
input_titles($file); //Add column titles
}
else
{
add_input_to_the_last_line($input);
}
Is there a library which can simply do the above?
You could use PHPExcel library:
Example Usage:
$objPHPExcel = new PHPExcel();
$objPHPExcel->setActiveSheetIndex(0);
$rowCount = 1;
while($row = mysql_fetch_array($result)){
$objPHPExcel->getActiveSheet()->SetCellValue('A'.$rowCount, <your_row_name>);
$objPHPExcel->getActiveSheet()->SetCellValue('B'.$rowCount, <your_row_name>);
$rowCount++;
}
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
$objWriter->save('your_file_name.xlsx');
