Replace a worksheet within an Excel workbook (.xlsx) without changing any other properties of the file.

Details

The main purpose of this library is adding a "data table" to an existing excel file without modifying any other components. This is especially useful if you have a template file, e.g. for reporting including "advanced" features like charts, pivot tables, macros and you'd like to change a base data table within a PHP application.

Setup

Use composer to add this repository to your dependencies:

{
  "require": {
    "svrnm/exceldatatables": "dev-master"
  }
}

If you use the Laravel framework you can additionally add the ServiceProvider to your config/app.php:

...
'providers' => array(
  ...
  'Svrnm\ExcelDataTables\ExcelDataTablesServiceProvider'
)
...

Example

The following example demonstrates how to use ExcelDataTables. The following is also contained as example.php within the folder examples/:

<?php
  require_once('../vendor/autoload.php');
  // Create a new instance
  $dataTable = new Svrnm\ExcelDataTables\ExcelDataTable();
  // Specify the source file
  $in = 'spec.xlsx';
  // Specify the output file
  $out = 'test.xlsx';
  // Specify the data for the worksheet.
  $data = array(
    array("Date" => new \DateTime('2014-01-01 13:00:00'), "Value 1" => 0, "Value 2" => 1),
    array("Date" => new \DateTime('2014-01-02 14:00:00'), "Value 1" => 1, "Value 2" => 0),
    array("Date" => new \DateTime('2014-01-03 15:00:00'), "Value 1" => 2, "Value 2" => -1),
    array("Date" => new \DateTime('2014-01-04 16:00:00'), "Value 1" => 3, "Value 2" => -2),
    array("Date" => new \DateTime('2014-01-05 17:00:00'), "Value 1" => 4, "Value 2" => -3),
  );
  // Attach the data table and copy the new xlsx file to the output file.
  $dataTable->showHeaders()->addRows($data)->attachToFile($in, $out);
?>

In this example the method attachToFile creates a new excel file. If you use this library within a web application you might prefer the fillXLSX() function which returns a string representation of the excel document. The following examples demonstrates this case within a Laravel application

<?php
  class ReportController extends Controller {
    protected $dataTable;

     public function __construct(\Svrnm\ExcelDataTables\ExcelDataTable $dataTable) {
         $this->dataTable = $dataTable;
  }

  public function show($month) {
   $data = DB::select('select date,value1,value2 from reporting where MONTH(date) = ?', array($month));
   $path = storage_path() . '/reports/example.xlsx';
   $xlsx = $this->dataTable->showHeaders()->addRows($data)->fillXLSX($path);
   return Response::make($xlsx, 200, array(
    'Content-Type' => 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
    'Content-Disposition' => 'attachment; filename="report.xlsx"',
    'Content-Length' => strlen($xlsx)
   ));
   // ...
  }
 }
?>
