I am hoping to find an Excel add-in that functions like the product from F9 but can be configured to work against our system data. (Unfortunately F9 does not supply a version that works with our software.) The data is in a SQL database.

With the F9 software, you can display general ledger data in a spreadsheet cell using a formula like "=gl(account,type,year,month)" where "account" references a cell that contains, for example, "11100" or "11100..11199", "type" references a cell that contains "actual" or "budget", and so forth.

I hope to use this as a spreadsheet "front-end", replacing my software's report writers, which are terrible.

Your help is appreciated!
