Get sheet data to array with given row range using Laravel Excel

I have a large number of data and I have to read data from csv file. I need to use toArray() with some chunk data reading or read given range of data from sheet. I have data around 45 columns and around 2.5 lacks rows at a time in one sheet.

I have tried to read using toArray() of laravel excel. But it takes too much time to read data. So I was thinking to read data using some range wise.
