Sum up specific cell range

[guevarawebgraphics]

Currently I can get the data from my excel file, for every sheet I can get the data collection. The problem is, I want to sum up the value of specific cell range.

For example, I have field of weight and I want to get the grand total of that field.

Once you get the collection object, you can use one of the standard laravel methods to calculate the total. It looks like you need to use "reduce". (https://laravel.com/docs/5.8/collections#method-reduce)
