Data Export Implementation from Web Application

Data Export Implementation

Export user data, transactions, analytics to structured formats. Requires user authentication, access control, rate limiting to prevent abuse.

Data Export Endpoint

class DataExportController
{
    public function export(Request $request)
    {
        $format = $request->query('format', 'json'); // json, csv, xlsx
        
        $data = [
            'user' => auth()->user(),
            'orders' => auth()->user()->orders()->get(),
            'transactions' => auth()->user()->transactions()->get(),
        ];
        
        return match($format) {
            'csv'  => $this->exportCsv($data),
            'xlsx' => $this->exportExcel($data),
            'json' => response()->json($data),
        };
    }
    
    private function exportCsv($data)
    {
        $csv = "ID,Name,Email\n";
        $csv .= "{$data['user']->id},{$data['user']->name},{$data['user']->email}\n";
        
        return response($csv, 200, [
            'Content-Type' => 'text/csv',
            'Content-Disposition' => 'attachment; filename="export.csv"',
        ]);
    }
}

GDPR Compliance

• Verify user identity
• Log all exports
• Limit export frequency (once per day)
• Expire download links after 7 days
• Delete exported files from storage

Implementation timeline

Basic data export: 1 day. With GDPR compliance and multiple formats: 2–3 days.
