 Laravel Excel is created with love and care by Spartner (formerly known as Maatwebsite) to give back to the Laravel community. It is completely free (MIT license) to use, however the package is licensed as Postcardware. This means that if it makes it to your production environment, we would very much appreciate receiving a postcard from your hometown.
