How to save correctly?

[ghost]

Heres what I am trying to do and probably doing it all wrong! But is there a way to update the object then re-write/save it?

I have read the file in as an object type. Converted it to json did some string replacements on it then converted it back to an object. Now I want to take that object and save it back out with the new variables in it.

Other Info:
Basically I have a template xlsx file with things like {{goal0}} so I want to be able to replace those with actual values and save it so I can send out a mass email with it updated.

After you have done your string replacements, you have to convert it to a nice array and give it to the ->with() method of Excel::create(). It will make a new excel file based on the array (which will have the replaced values)

Example of how the array should look

$array = array(
        array('A1','B1'),
        array('A2','B2')
);

Example of the Excel parts:

// Load file into object
$object = Excel::load('file.xlsx')->toObject();

// Do your replace functions

// Convert to an array

// Export to excel
$excel =  Excel::create('export_filename')
           ->sheet('sheetName')
           ->with($array)
          ->store('xlsx', false, true);

// Get the file to use it as attachment
$filename = $excel['full'];
