anik/dataset is a PHP package for importing & exporting data within CSV & Database. You can use joins from multiple tables. Create new columns for CSV, based on some calculation on available data. You don't need to put extra pressure on your database anymore. Dataset supports all the databases which are supported by Laravel/Lumen. Because, internally it uses Laravel's database package.

To install via composer, type

composer require "anik/dataset" "^3.0"

A few examples are given in examples directory.

Check the documentation here.

I'd always appreciate if you find any bug, fix it and send a PR. Every type of contributions are appreciated.
