Load spreadsheet from memory.

What is the expected behavior?

I'm taking a spreadsheet from an email and processing it. I'd prefer to move it directly into PhpSpreadsheet without needing to save it to a file first, because that takes time and I have to delete the file after I'm done with the data anyway.

What is the current behavior?

Currently, I need to download an attachment, save it as a file, load the file into PhpSpreadsheet, process the information, and then delete the saved file.

What are the steps to reproduce?

Please provide a Minimal, Complete, and Verifiable example of code that exhibits the issue without relying on an external Excel file or a web server:

Sorry this isn't complete, but I think you get the idea: I would like to go directly from the decoded email attachment into PhpSpreadsheet. This would save a lot of processing for us.

<?php

require __DIR__ . '/vendor/autoload.php';

// Create new Spreadsheet object
$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();

// add code that show the issue here...
                $rawAttachment = imap_fetchbody($connection, $msg, 1);
                if ($structure->encoding == 3) {
                    $attachment = base64_decode($rawAttachment);
                }
                elseif ($structure->encoding == 4) {
                    $attachment = quoted_printable_decode($rawAttachment);
                }

                $fileName = $msg . "_" . $structure->parameters[0]->value;
                file_put_contents($fileName, $attachment);

                $filExt = explode(".", $fileName);
                $extension = ucfirst(end($filExt));
                $reader = \PhpOffice\PhpSpreadsheet\IOFactory::createReader($extension);
                $spreadSheet = $reader->load($fileName);

Which versions of PhpSpreadsheet and PHP are affected?

Hi

You can use bovigo/vfsStream virtual filesystem library to avoid writing on the hard drive.

Thanks, but I'm not really looking for a work around. I'd prefer to have less code in the project, not more.

This seems like an obviously valuable feature to have, so I'm a bit surprised that it doesn't already exist.

Yes I agree with you, this should be possible to read or save as string. Or at least Steams.
