The results of uncommenting the statements will often not be successful.
In Excel, if I enter `=MINVERSE({2,0;0,1})` into cell A1, you will get a
`dynamic array` (which we do not yet support) - A1 will contain 0.5, A2
and B1 will contain 0, and B2 will contain 1. There are also `spill`
implications for such a formula. The XML for these cells will be:
``` xml
<row r="1" spans="1:2" x14ac:dyDescent="0.3">
<c r="A1" cm="1">
<f t="array" ref="A1:B2">MINVERSE({2,0;0,1})</f>
<v>0.5</v>
</c>
<c r="B1">
<v>0</v>
</c>
</row>
<row r="2" spans="1:2" x14ac:dyDescent="0.3">
<c r="A2">
<v>0</v>
</c>
<c r="B2">
<v>1</v>
</c>
</row>
```
I believe that the PhpSpreadsheet equivalent of doing this (with the statements
uncommented) is:
```php
$spreadsheet = new Spreadsheet();
$calculation = Calculation::getInstance($spreadsheet);
$calculation::setArrayReturnType(Calculation::RETURN_ARRAY_AS_ARRAY);
$sheet = $spreadsheet->getActiveSheet();
$sheet->getCell('A1')->setValue('=MINVERSE({2,0;0,1})');
$writer = new Xlsx($spreadsheet);
$oufil = 'issue.2343.xlsx';
$writer->save($oufil);
```
But our output file only fills in A1:
```xml
<row r="1" spans="1:1">
<c r="A1">
<f>MINVERSE({2,0;0,1})</f>
<v>0.5</v>
</c>
</row>
```
And, even though A1 has its correct value, note that its `f` tag does not have
a `t` attribute. This is because we never set any formula attributes, except
in Xlsx Reader (see next paragraph), so we do not encounter the `'array'`
condtion for a formula newly added to a spreadsheet.
We do slightly better when we read the first file (as opposed to creating a new
spreadsheet), but we succeed only by accident. Because B1, A2, and B2 are
assigned values in the XML, all 4 cells will have the expected values. But they
are now independent of each other, not part of a dynamic array. When we write
this out, it is almost correct:
```xml
<row r="1" spans="1:2">
<c r="A1">
<f>MINVERSE({2,0;0,1})</f>
<v>0.5</v>
</c>
<c r="B1">
<v>0</v>
</c>
</row>
<row r="2" spans="1:2">
<c r="A2">
<v>0</v>
</c>
<c r="B2">
<v>1</v>
</c>
</row>
```
Again, the `f` tag has no `t` attribute, and it doesn't seem to matter whether we set
RETURN_TYPE_ARRAY or not. I think this particular aspect of the problem might be
relatively easy to fix.

PhpSpreadsheet
PhpSpreadsheet is a library written in pure PHP and offers a set of classes that allow you to read and write various spreadsheet file formats such as Excel and LibreOffice Calc.

PHPExcel vs PhpSpreadsheet ?
PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet master branch.
Do you need to migrate? There is an automated tool for that.
