scslmd here has created an excel macro to convert the exported AC billing file to tab delimited, which can be uploaded to office ally.
scslmd has offered his macro for use, and OA is free (if <=50% medicare/medicaid claims), and that's the cheapest i know of.
i am a longtime AC user (since 2002), but i confess, i haven't cruised these forums for a long time, and i'm glad to know others here are working to find similar solutions.
thanks, all, and i will do my best to offer solutions myself.
