I was able to successfully import a GL batch (detail-only style) into Adagio Ledger 8.0B where I saved the import file as Lotus format (*.wk1) using MS Excel.

- Which version of Adagio Ledger are you running?
- Adagio Receivables import batches is currently limited to CSV, PSV and Fixed length formats, even if you select Excel. Perhaps if you are running an older version of Ledger, this limitation is (still) there?
