I'm trying out Box\Spout and rewriting some code which was formerly using PHPExcel. Iterating through rows is clear but in a few cases I need to address directly one specific row. I cannot find this in the documentation.
Something like:
$row = $sheet->getRow(8);
You can't access rows directly. If you need the 8th row, you'll need to read the first 8 rows... This is because Spout does not load the entire spreadsheet in memory so it reads the data row by row.
However, you can do something like this:
foreach ($reader->getSheetIterator() as $sheet) {
foreach ($sheet->getRowIterator() as $rowIndex => $row) {
if ($rowIndex !== 8) {
continue;
}
// do something with row 8
}
}
Try using the iterator's key() method:
$it = $sheet->getRowIterator();
$row = $it->key(8);
I'm trying to read a merged cell in phpexcel, my problem is that the cell is merged on A:B:C:D:E:F ( can't argue with what they want )
$i= 0;
foreach ($worksheet->getRowIterator() as $row) {
if ($i > 10) break ;
$i ++;
$cellIterator = $row->getCellIterator();
foreach ($cellIterator as $cell) {
if($cell->getColumn()== 'A:B:C:D:E:F'){
$specification=$cell->getCalculatedValue();
var_dump($specification);die();
// some other code
always dumps null.
I've tried $cell->getColumn()== 'A' since that the cell starts at A, but dumps null as well.
I would appreciate any help.
I don't understand exactly what you're trying to do here, because getColumn() will only ever return a single column address like A or B and never anything like 'A:B:C:D:E:F'
It may be sensible to iterate only existing cells using
$cellIterator->setIterateOnlyExistingCells(true);
but there's a couple of functions that may help you with merged cells:
$cell->isInMergeRange()
will return a Boolean true/false, indicating if the cell is part of a merge range
and
$cell->isMergeRangeValueCell()
can be used to test whether a cell within a merge range is the top-left (primary) cell of that range, and will return a Boolean true/false indicating whether it holds the actual data value/type etc for that range... Note that it will return a false if the cell isn't part of any merge range
I made the follow function for get a matrix from a worksheet.
private function getMatrixFromSheet($worksheet){
foreach ($worksheet->getRowIterator() as $row) {
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false);
foreach ($cellIterator as $cell) {
if (!is_null($cell)) {
$matrix[$cell->getRow()][$cell->getColumn()] = $cell->getCalculatedValue();
}
}
}
return $matrix;
}
In this way if I want to access to the second row, second col cell, I can do $matrix[2]['B'].
I need to be able to access to the matrix indexes both as number in order to access to the previous cell as $matrix[2][2].
Is there a way to do this?
I try to convert $cell->getColumn() result in a integer, but unfortunately (int) "a" == 0
If you just want a numeric value for the column, then PHPExcel provides a static helper method to do precisely that
$columnIndex = PHPExcel_Cell::columnIndexFromString($cell->getColumn());
Which returns 1 for column A, 2 for column B, 27 for column AA, 28 for column AB, etc
However, you might find that you can simplify your function completely, because PHPExcel also provides the toArray() method to do exactly what you've written this method for:
private function getMatrixFromSheet($worksheet){
return $worksheet->toArray();
}
Note that row/column offsets for the matrix returned by toArray() are 0-based
I'm trying to use PHPExcel to create a website that checks consistency of data in excel files.
I manage to load the excels but now I need to pass some checks on the data, and I can't figure out how. For example some of the checks would be:
Count number of empty cells in a specific column
Count number of non integer values in a specific column
Check that a column only has values that are contained in another one of the excels.
Are there some functions that do a kind of count where on the columns?
Or some way to iterate through the values to achieve this goals?
Thank you
Like Mark said, once I used PHPExcel to put the data into arrays I managed to do the checks myself. Here is an example of logging the empty cells of a column:
$n_row=0;
$divisasNull=0;
foreach ($sheetdata as $row) {
$n_column=0;
foreach ($row as $cell) {
if($n_column==6)
{
if($cell==null)
{
echo 'Error. Empty currency at row: '.$n_row.'<br>';
$divisasNull++;
}
}
$n_column++;
}
$n_row++;
}
echo 'Total errors: '.$divisasNull;
I have an array that can store numbers in such as 01, 01A, 01B, 02, 2, and When I get this value using PHPExcel, it's being removed the '0's in case of 01, 02, for example. To solve this problem, I tried to format the row where these values will be stored in excel and set it as text type, just like in the following code:
$objPHPExcel->setActiveSheetIndexByName('BlocksList');
$objPHPExcel->getActiveSheet()->fromArray($blockNames, null, 'A2');
$latestBLColumn = $objPHPExcel->getActiveSheet()->getHighestDataColumn();
$column = 'A';
$row = 1;
for ($column = 'A'; $column != $latestBLColumn; $column++) {
$objPHPExcel->getActiveSheet()->getStyle($column.$row)->getNumberFormat()->setFormatCode( PHPExcel_Style_NumberFormat::FORMAT_TEXT );
}
$objPHPExcel->getActiveSheet()->fromArray($blockNames, null, 'A1');
So, by doing this, I get the array with numbers like 01, 01A, 02, 02B... and I store it in the Row A2. I get the highest Column to use this value in the condition For. In this condition, I set for the Row 1 in the range A until the highest column, to be formated as text.
My template is generated, and all the numbers are in text format, but the problem is that I think when I use the "fromArray()" method, it transforms the numbers of the array before I can get it right in excel.
Do you have any idea of how can I solve this problem??
Formatting using a number format affects the way a number is displayed, not the way it is stored.
You'll have to store the numbers explicitly as strings, so you can't use fromArray().
Use setCellValueExplicit() or setCellValueExplicitByColumnAndRow() instead, passing a $pDataType argument of PHPExcel_Cell_DataType::TYPE_STRING.
EDIT
Note that you can also set styles for a range of cells, so there's no need to add the overhead of the for loop:
$range = 'A'.$row.':'.$latestBLColumn.$row;
$objPHPExcel->getActiveSheet()
->getStyle($range)
->getNumberFormat()
->setFormatCode( PHPExcel_Style_NumberFormat::FORMAT_TEXT );
EDIT #2 Using a cell binder
Create a customised cell value binder:
class PHPExcel_Cell_MyValueBinder extends PHPExcel_Cell_DefaultValueBinder
implements PHPExcel_Cell_IValueBinder
{
public function bindValue(PHPExcel_Cell $cell, $value = null)
{
// sanitize UTF-8 strings
if (is_string($value)) {
$value = PHPExcel_Shared_String::SanitizeUTF8($value);
}
// Implement your own override logic
if (is_string($value) && $value[0] == '0') {
$cell->setValueExplicit($value, PHPExcel_Cell_DataType::TYPE_STRING);
return true;
}
// Not bound yet? Use default value parent...
return parent::bindValue($cell, $value);
}
}
To avoid any problems with the autoloader, create this in the /Classes/PHPExcel/Cell directory. Otherwise, give the class your own non-PHPExcel name, and ensure that it's loaded independently.
Then, before using your fromArray() call, tell PHPExcel to use your value binder instead of the default binder:
PHPExcel_Cell::setValueBinder( new PHPExcel_Cell_MyValueBinder() );
In case you need to convert the whole sheet numbers to text, you can use calculateWorksheetDimension() to get the sheet's dimensions (example: 'A1:B200' or 'A1:C150') and then use it in getStyle(), like so:
// Get sheet dimension
$sheet_dimension = $spreadsheet->getActiveSheet()->calculateWorksheetDimension();
// Apply text format to numbers
$spreadsheet->getActiveSheet()->getStyle($sheet_dimension)->getNumberFormat()->setFormatCode(\PhpOffice\PhpSpreadsheet\Style\NumberFormat::FORMAT_TEXT);
Note: This example uses PhpSpreadsheet since it is the next version of PHPExcel.
I know this was all posted a while ago, but wanted to share something that worked for me, so you can still use ->fromArray and not have to iterate over the whole spreadsheet.
If you wrap your values in ="VALUE" it will come through as text, and not convert it, and it will not have quotes around it in your spreadsheet
$objPHPExcel
->getActiveSheet()
->getCellByColumnAndRow($col, $row)
->setValueExplicit($value, PHPExcel_Cell_DataType::TYPE_STRING);
You can format value to text with add charater before or after value. Example add after value charater ";"
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow(1, $row,$user->msisdn.';' );
Try this :
$objPHPExcel->getActiveSheet()->setCellValueExplicit("A1","yourvalue",PHPExcel_Cell_DataType::TYPE_STRING);
please see here setCellValueExplicit function : https://github.com/PHPOffice/PHPExcel/blob/1.8/Classes/PHPExcel/Worksheet.php
