## Creating a spreadsheet
|
|
|
|
### The `Spreadsheet` class
|
|
|
|
The `Spreadsheet` class is the core of PhpSpreadsheet. It contains references to the contained worksheets, document security settings and document meta data.
|
|
|
|
To simplify the PhpSpreadsheet concept: the `Spreadsheet` class represents your workbook.
|
|
|
|
Typically, you will create a workbook in one of two ways, either by loading it from a spreadsheet file, or creating it manually. A third option, though less commonly used, is cloning an existing workbook that has been created using one of the previous two methods.
|
|
|
|
#### Loading a Workbook from a file
|
|
|
|
Details of the different spreadsheet formats supported, and the options available to read them into a Spreadsheet object are described fully in the PhpSpreadsheet User Documentation - Reading Spreadsheet Files document.
|
|
|
|
```php
|
|
$inputFileName = './sampleData/example1.xls';
|
|
|
|
/** Load $inputFileName to a Spreadsheet object **/
|
|
$spreadsheet = \PhpOffice\PhpSpreadsheet\IOFactory::load($inputFileName);
|
|
```
|
|
|
|
#### Creating a new workbook
|
|
|
|
If you want to create a new workbook, rather than load one from file, then you simply need to instantiate it as a new Spreadsheet object.
|
|
|
|
```php
|
|
/** Create a new Spreadsheet Object **/
|
|
$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();
|
|
```
|
|
|
|
A new workbook will always be created with a single worksheet.
