+#### Preserve date formatting
+
+By default, when reading a spreadsheet with dates or times, the values are returned as `DateTimeImmutable` objects. To return a formatted date (e.g., “9/20/2024”) instead, use the `preserveDateTimeFormatting` method. The date format will match what’s specified in the spreadsheet.

+```php
+$rows = SimpleExcelReader::create($pathToXlsx)
+    ->preserveDateTimeFormatting()
+    ->getRows();
+```
+
+#### Preserve empty rows
+
+You can preserve empty rows by using the `preserveEmptyRows` method.
+
+```php
+$rows = SimpleExcelReader::create($pathToXlsx)
