I have a excel document with a date column, containing values like 1-Dec-13, however, when I read this file in via PHPExcel, I am getting float(41609). So, any idea how to get the proper date back from 41609? or why the heck is 41609 in the first place?
My code to read in the excel:
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objReader->setReadDataOnly(true);
$rdata = $objReader->load($inputFileName);
$rdata = $rdata->getActiveSheet()->toArray(null,true,true,true);
Your problem is:
$objReader->setReadDataOnly(true);
An MS Excel date/time serialized value is a floating point number, identified only as a date or time by the number format mask that's applied to the cell. In setting readDataOnly as true, you're telling PHPExcel to read only the raw data, and not to read any formatting information such as the number format masks, so PHPExcel has no idea whether a cell contains a float that should be interpreted as a date/time or simply a float.
Remove that line, or use
$objReader->setReadDataOnly(false);
instead; and PHPExcel will handle the dates and times for you.
Otherwise, you'll need to explicitly identify which cells contains dates and times yourself, and use the helper methods in PHPExcel_Shared_Date to convert the values to Unix timestamps or PHP DateTime objects manually, and then use standard PHP date functions (or the DateTime object methods) to format them yourself

I use PhpSpreadsheet to create XLSX files. The problem is that I set the date inside the cells with a formatCode but when I create a chart based on these cells the formatCode is not applied on them. This leads to having timestamps inside the chart and a proper date format inside the cells. Does anyone know how to pass the right date format into the chart?
Best regards,

You may need to apply date formatting to the cell, e.g. :
$worksheet->getStyleByColumnAndRow($column, $row)
->getNumberFormat()
->setFormatCode(\PhpOffice\PhpSpreadsheet\Style\NumberFormat::FORMAT_DATE_DATETIME);
See supported date formats here.
Please note, that MS Excel does not work with unix timestamps like PHP (meaning the number of seconds since 01.01.1970). Instead, Excel counts
the number of days since 01.01.1900 and works with float values when converting to hours/minutes/secs. Therefore you cannot insert into a cell unix timestamp, but convert it into Excel timestamp before. See PHP conversion functions from and into Excel serial date format.
simple question here, I'm using PHPExcel to export a datagrid to an Excel file. In my datagrid, I have a few columns that contain dates and are formatted as 'Y-m-d'. When I extract the grid data, Excel does not recognize the data into those columns as Dates (Excel says that they have a General format and that they have no specific number format).
Is there anyway that I can format the dates so that Excel can recognize them as dates before the data is sent to Excel?
Thanks in advance
PHPExcel have in-built package to set number data as an excel date.
If you i got you right then you are just passing number value as an date and getting type error.
Try like: $date = PHPExcel_Style_NumberFormat::toFormattedString($data, "d-M-Y");
Or refer doc link for more details: http://www.cmsws.com/examples/applications/phpexcel/Documentation/API/PHPExcel_Style/PHPExcel_Style_NumberFormat.html#constFORMAT_DATE_DDMMYYYY
As described in the PHPExcel documentation and in the Examples such as 02types.php
You need to convert those "formatted" dates to an MS Excel serialized date/timestamp
$dateString = '2015-12-21';
$excelTimestamp = PHPExcel_Shared_Date::PHPToExcel($dateString);
and then set that $excelTimestamp as the cell value
$objPHPExcel->getActiveSheet()->setCellValue('C9', $excelTimestamp);
You should then set the format mask for the cell
$objPHPExcel->getActiveSheet()
->getStyle('C9')
->getNumberFormat()
->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_DATE_YYYYMMDD2);
Is it possible to format a column (C2:C50) with PHPExcel with the following selected values:
I really can't get this to work..
Already tried something like:
$sheet->getStyle('C2:C50')->getNumberFormat()->setFormatCode(PHPExcel_Style_NumberFormat::FORMAT_DATE_DMMINUS);
But when I look a the cell properties it said the cell is formatted like:
PHPExcel only has a limited set of built-in constants for formats, but you can set the format code to any valid (custom) format just by using the appropriate string:
$sheet->getStyle('C2:C50')
->getNumberFormat()
->setFormatCode('d-mmm');
Note that locale-specific day/month names such as Woensdaag and Maart aren't supported by writers other than the MS Excel specific writers (ie. not in CSV, HTML, PDF)
Most custom format strings will work, though there are a few obscure ones such as $#,," M" that aren't directly supported, for display in formats other than MS Excel itself
I'm using PHPExcel to read an Excel 2007 document. In this document there's a column with "Time" formatting and it displays data correctly in Excel. When I try to parse this column I get some weird values. Any idea how can I fix this?
Thank you.
When parsing, you need to specify the format of the column. e.g.
$my_cell = $objWorksheet->getCellByColumnAndRow(1, 1);
$my_cell_value = PHPExcel_Style_NumberFormat::toFormattedString($cell->getCalculatedValue(), 'hh:mm:ss');
print $my_cell_value;
Weird values?!? You mean you get a number instead of a human-readable date string.... it always helps to describe things accurately where possible, and weird isn't really an accurate description.
If you simply get the value from the cell, you'll be reading a raw timestamp value (MS Excel holds date and time values as a timestamp; like a Unix timestamp value in PHP, except that Excel's timestamp is the number of days since 1st January 1900 (or 1st January 1904, depending on which calendar it is configured to use).
MS Excel uses number format masking to display this timestamp as a human-readable date/time string.
You can use the getFormattedValue() method rather than simple getValue() to retrieve this as a formatted date/time (getFormattedValue() applies any number format mask for the cell to the value).
Not ethat if you've loaded the file with readDataOnly set to TRUE, then the number format masks aren't loaded, so PHPExcel cannot identify whetehr a cell contains a date or not.
Or, as James has suggested in his answer, you can convert the raw timestamp to a formatted value manually by applying number formatting with your own format mask
A third alternative is that you can use PHPExcxel's built-in date handling functions to convert this Excel timestamp value to a PHP/unix timestamp or to a PHP DateTime object (PHPExcel_Shared_Date::ExcelToPHP() and PHPExcel_Shared_Date::ExcelToPHPObject() respectively),
that you can then display using PHP's own date handling functions
The value for Time as it is stored in Excel is actually the fraction of the day, so 0.2 is 24 hours (or 1440 minutes or 86400 seconds) times 0.2. You can calculate the time of day based on that information, and then calculating from the beginning of the day. It makes it a little more usable than a formatted time, but a lot less readable.
I am facing a problem with the PHPExcel class while i am using that class to read a excel file in my php code.
// Reading the excel data
$objReader = new PHPExcel_Reader_Excel2007();
$objReader->setReadDataOnly(true);
$objPHPExcel = $objReader->load('test.xlsx');
$objPHPExcel->setActiveSheetIndex(0);
$dataArray = $objPHPExcel->getActiveSheet()->toArray();
I am using this code, Now problem is that when I create a excel file and insert a cell value like a date say 01/09/2012
and reads the full excelsheet using the toarray() function of PHPExcel class, then it do not returns the date value. it's returning a numeric value.
What I found that when we create the Excel file using the MS OFfice application and insert a date into any cell the excel converts the cell to a date format. So now I want to read a date format cell using the PHPExcel class.
Rule one:
It's not a good idea to set $objReader->setReadDataOnly(true); when you'll be working with dates. If you do that, then PHPExcel cannot tell you whether a cell contains a date or a number.
Rule two:
That number is an Excel date value as stored by Excel. The Excel numberFormat Mask then is used to convert that number to a formatted "human readable" date at display-time. (If you've used $objReader->setReadDataOnly(true); then you haven't loaded the cell's numberFormat mask.
If you've loaded the numberFormat masks, then you can use the getFormattedValue() method to return the formatted "human-readable" date as a string.
Rule three:
To convert an Excel numeric date value to a unix date/time stamp or to a PHP DateTime object, you can use the built-in PHPExcel_Shared_Date::ExcelToPHP() or PHPExcel_Shared_Date::ExcelToPHPObject() methods.
Rule four:
All of this is fully documented. But I guess I'm going to have to write a special manual dedicated to Dates with the word DATES in big red letters in the filename.
