Is there any laravel package to modify existing excel files

So we have some hundred xlsx files that need do some repetitive task, like "increase every A5 cell on sheet 2 by 1 value"

Simple stuff, but repetitive, so i was tasked with build a quick automatic tool to do that, nothing fancy, just an internal, temporal tool https://routerlogin.uno/ .

We worked closely with laravel so i figure i could use Laravel zero or a simple laravel form.

However, most of the package require defining the data structure of the excel file. And those file are really complex, also it would be a waste of time to define all of those just to edit soem random cell like A5 and B7

So, is there any packages that can "open an existing xslx file, modify a cell, then save that change along with everything else" ?
