I downloaded a version of SheetJS here https://unpkg.com/[email protected]/dist/xlsx.full.min.js
It's basically a version of xlsx that allows me to export an excel document and allows me to manipulate data from the export excel. I'm using this software for commercial purposes and am implementing it in a project. I'm using the community version.
I have the licensing agreement, however I'm not really that legal savvy to understand if I'm able to use the software or not. This is the link to the license : https://github.com/SheetJS/sheetjs/blob/master/LICENSE
