What is the expected behavior?

I should be able to parse cells with line breaks.

What is the current behavior?

The package throws and exception because there's a row with multiple cells with line breaks. When I remove the row with line breaks it starts working again.

What is the expected behavior?

This code is not calculating formulas with read filters. If I change $chunk_read_filter->setRows(1500, 3000); to $chunk_read_filter->setRows(1, 3000); it works. It need to calculate formulas with the range. My all formulas are in range and within same row.

What is the expected behavior?

Theme/scheme colors should be read as part of Xlsx Reader, and reproduced by Xlsx Writer.

What is the current behavior?

Reader appears to ignore scheme colors. Writer appears to write theme file with hard-coded colors. As a result, the input and output files may differ in their coloring when scheme colors are used. This is especially noticeable in some charts (see PR #3476); I suspect, but am not certain, that other situations might also be affected.

There appears to be a bug when applying a number format to a Style instance when Style was created with a CellAddress instance that has got a Worksheet instance defined.

What is the expected behaviour?

Style instance to be retrieved for further use.

What is the current behaviour?

An exception is thrown due to "Invalid cell coordinate". Stack trace is as follows:

PhpOffice\PhpSpreadsheet\Exception:
Invalid cell coordinate 'CLIENT ACCOUNTS'!N2

  at vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Cell/Coordinate.php:42
  at PhpOffice\PhpSpreadsheet\Cell\Coordinate::coordinateFromString('\'CLIENT ACCOUNTS\'!N2')
     (vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Style/Style.php:218)
  at PhpOffice\PhpSpreadsheet\Style\Style->applyFromArray(array('numberFormat' => array('formatCode' => 'yyyy/mm/dd;@')))
     (vendor/phpoffice/phpspreadsheet/src/PhpSpreadsheet/Style/NumberFormat.php:186)
  at (blah blah Symfony framework stuff here)

What are the steps to reproduce?

First create an instance of a CellAddress class and specify its worksheet instance.
Then try to apply a number format to that cell by passing through the CellAddress instance.

/** @var \PhpOffice\PhpSpreadsheet\Worksheet\Worksheet $worksheet */
$worksheet = ...;

// Make a `CellAddress` instance. This would usually be necessary for more complex iterators and such worksheet building code.
$cellAddress = new \PhpOffice\PhpSpreadsheet\Cell\CellAddress("A1", $worksheet);

// Grab a `Style` instance for that `CellAddress` to do whatever presentation necessary.
$style = $worksheet->getStyle($cellAddress);

// Crash here when applying a number format to the cell(s) in question.
$style->getNumberFormat()->setFormatCode(\PhpOffice\PhpSpreadsheet\Style\NumberFormat::FORMAT_DATE_YYYYMMDDSLASH);

This problem does not occur if you omit the worksheet instance when building the CellAddress instance, though you may need to reference the worksheet later.

What features do you think are causing the issue

Most likely Styles.

Does an issue affect all spreadsheet file formats? If not, which formats are affected?

This happens when building a spreadsheet prior to a file save. We typically export as XLSX though I suspect this issue isn't related to the desired format of the resulting spreadsheet.

Which versions of PhpSpreadsheet and PHP are affected?

Tried on PhpSpreadsheet version 1.24.0. PHP version is 7.3 because "insert mundane project specific reasons here", though this issue doesn't appear to be related to the PHP version.

Looking through the same stack trace on the current version (1.28.0 at time of writing) the issue will occur here too as the relative code is unchanged.

On closer inspection

At the deepest point the issue occurs when \PhpOffice\PhpSpreadsheet\Cell\Coordinate::coordinateFromString() tries to parse a cell address that contains a worksheet, e.g. "'CLIENT ACCOUNTS'!N2".

Looking up the stack trace there are a number of opportunities in which the worksheet name could be cut out of the cell address, and I'm probably not best placed to decide where this would be best done. Essentially the following needs to happen somewhere:

if (false !== ($worksheetNameMarker = strrpos($cellAddress, '!'))) {
    $cellAddress = substr($cellAddress, $worksheetNameMarker + 1);
}

There are 2 reasonable places for this to happen:

1. \PhpOffice\PhpSpreadsheet\Cell\Coordinate::coordinateFromString(): Immediately, before trying to parse the coordinate string.
2. \PhpOffice\PhpSpreadsheet\Style\Style::applyFromArray(): Just after retrieving the selected cells? Though using variable name $pRange instead of $cellAddress.
   $pRange = $this->getSelectedCells();

I suspect the 2nd point (Style::applyFromArray()) would be most appropriate because Coordinate::coordinateFromString is not even expecting a range of cells at this deep point. This function already iterates over the range of cells (if a range was provided), so if the specific worksheet part of the coordinate is no longer necessary this would be a good chance to cut it.

Whichever position, this would correct "'CLIENT ACCOUNTS'!N2" to "N2" and all continues to work as expected.

What is the expected behavior?

The Excel EOMONTH() and EDATE() functions should always return a float with the date, but with the time truncated to 0.

e.g.

EOMONTH(22269.75, 3) should result in float 22371.0
EDATE(22269.75, 2) should result in float 22331.0

What is the current behavior?

If the dateValue argument to EOMONTH() includes a time, then the result also includes that time.

EOMONTH(22269.75, 3) results in float 22371.75
EDATE(22269.75, 2) results in float 22331.75

What are the steps to reproduce?

Please provide a Minimal, Complete, and Verifiable example of code that exhibits the issue without relying on an external Excel file or a web server:

<?php

require __DIR__ . '/vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Calculation\DateTimeExcel\Month;

$dateValue = 22269.75;
$adjustment = 3;
$result = Month::lastDay($dateValue, $adjustment);
var_dump($result); // Should be (float) 22371.0 but is (float) 22371.75

$dateValue = 22269.75;
$adjustment = 2;
$result = Month::adjust($dateValue, $adjustment);
var_dump($result); // Should be (float) 22331.0 but is (float) 22331.75

Unsure as I only output XLSX format.

-- Note, I fixed this issue for myself (in a decidedly poor way) by modifying Writer/Xlsx/FunctionPrefix.php
I commented out one row in the file:

        . '|csch'
#        . '|days'
        . '|dbcs'

The function addXlfnPrefix is being overly aggressive and while it may be correct to modify the "DAYS" function to be "_xlfn.DAYS" the preg_replace is also doing this to the "NETWORKDAYS" by converting it to "NETWORK_xlfn.DAYS" which it either (1) should not do or (2) should do it correctly.

My workaround is fine for my situation, but this will likely cause others problems as well.

Tried Composer, it changed system settings and found lots of issues with php.ini. saying modules not found in ext folder but I visually found them.
Do not have enough time to fixing Composer issue.
why don't PhpSpreadsheet consider a version without Composer?

During HTML to Excel conversion, it is sometimes necessary to know what date type should be used :

                <table>
                    <tr>
                        <!-- boolean data type -->
                        <td data-type="b">1</td>
                        <!-- string data type -->
                        <td data-type="s">12345678987654321</td>
                        <!-- formula data type -->
                        <td data-type="f">=CONCAT("TEXT A ","TEXT B")</td>
                    </tr>
                </table>

Currently PhpSpreadsheet buffers the xlsx until it's written out to a stream which will be a problem if the generated dataset is very large.

Apache POI has a streaming implementation (https://poi.apache.org/spreadsheet/) where it solves this by restricting the operations if using it in a streaming mode.

• Only a limited number of rows are accessible at a point in time.
• Sheet.clone() is not supported.
• Formula evaluation is not supported

Would it be possible to add something similar to PHPSpreadsheet?

Charts to represent custom values passed to $dataValues parameter.

This is based on the line graph example: https://github.com/PHPOffice/PhpSpreadsheet/blob/master/samples/Chart/33_Chart_create_line.php

Place null for $dataSources parameter and place an array of values for the $dataValues parameter of DataSeriesValues.

I have asked about this at StackOverflow already thinking it was a usage issue (it may be) and have not received a response. However, I did today see this issue raising the same exact issue. The apparent solution was exactly what I am trying to do (pass an array of values to $dataValues). That user had success apparently. Maybe there is an issue with line graphs? I do not know.
