What i'm trying to do is this, I have an sql table, in the table, there are 2 columns that contain user id's. I'm trying to collect the data for each of the id's. this data was going to be written to an xlsx file. the data needed to create the xlsx file is an array of arrays. so i was thinking about making a hash, that contains each of the id's, and then for each of those id's it points to an array of arrays that I can use to create the spreadsheet. Is there some other way that would be more elegant to get this done?
