@QuickData.ai

tried quickdata on a stack of rent rolls (pdf+xls), a couple T12s and one chunky OM. setup's just an excel add in, super barebones ribbon button and it goes straight to work (no gimmicks). it mapped a lot of line items correctly and dumped them into my model fast. i like that it plugs into your existing model instead of forcing theirs. a clearer "why" for each auto category would be good.
