omg dude - shouldn't these users be querying a database in some capacity where this data resides in the first place?
perhaps via some more "accountant friendly" app than SQL?
That said, I suppose that's partly the goal of this product... a visual/faster alternative to SQL though I personally avoid putting big data in excel, I just (as an accountant myself) carve out subsets from SQL and then peruse it via excel to identify whatever transactions/activity I need to analyze since the web interface for the ERP is such slow steaming garbage...
I'm more in search of a better excel than an excel which can handle big data as I suspect many users will somehow, no matter how well this is built, make it slow/terrible whereas an SQL based approach could be multiple of orders of magnitude faster....
