### Date/Time formatting
When reading a spreadsheet containing dates or times, {{ site.spout_html }} returns the values by default as DateTime objects.
When reading a spreadsheet containing dates or times, {{ site.spout_html }} returns the values by default as `DateTime` objects.
It is possible to change this behavior and have a formatted date returned instead (e.g. "2016-11-29 1:22 AM"). The format of the date corresponds to what is specified in the spreadsheet.

## Empty rows
By default, when {{ site.spout_html }} reads a spreadsheet it skips empty rows and only return rows containing data.
This behavior can be changed so that {{ site.spout_html }} returns all rows:

## Styling rows
## Styling
It is possible to apply some formatting options to a row. {{ site.spout_html }} supports fonts, background, borders as well as alignment styles.
### Available styles
{{ site.spout_html }} supports styling at a row and cell level. It is possible to customize the fonts, backgrounds, alignment as well as borders.
For fonts and alignments, {{ site.spout_html }} does not support all the possible formatting options yet. But you can find the most important ones:
| Category | Property | API
|:----------|:--------------|:--------------------------------------
| Font | Bold | `StyleBuilder::setFontBold()`
| | Italic | `StyleBuilder::setFontItalic()`
| | Underline | `StyleBuilder::setFontUnderline()`
| | Strikethrough | `StyleBuilder::setFontStrikethrough()`
| | Font name | `StyleBuilder::setFontName('Arial')`
| | Font size | `StyleBuilder::setFontSize(14)`
| | Font color | `StyleBuilder::setFontColor(Color::BLUE)`<br>`StyleBuilder::setFontColor(Color::rgb(0, 128, 255))`
| Alignment | Wrap text | `StyleBuilder::setShouldWrapText(true|false)`
### Styling rows

->setFontSize(11)

In addition to passing a reader type to ```ReaderEntityFactory::createReader```, it is also possible to provide a path to a file and create the reader.
Note that {{ site.spout_html }} guesses the reader type based on the file extension. If the extension is not standard (`.csv`, `.ods`, `.xlsx` _- lower/uppercase_), the reader type needs to be specified:
```php
use Box\Spout\Reader\Common\Creator\ReaderEntityFactory;
use Box\Spout\Common\Type;

Similar to the reader, if the file extension of the file to be written is not standard, specific writers can be created this way:
```php
use Box\Spout\Writer\Common\Creator\WriterEntityFactory;
use Box\Spout\Common\Entity\Row;
$writer = WriterEntityFactory::createWriter(Type::XLSX);
// $writer = WriterEntityFactory::createWriter(Type::ODS);
// $writer = WriterEntityFactory::createWriter(Type::CSV);
```
For XLSX and ODS files, the number of rows per sheet is limited to *1,048,576*. By default, once this limit is reached, the writer will automatically create a new sheet and continue writing data into it.
