Can I undo an import without losing later edits?

Open your import history under You → Privacy and data → Import history, choose the import and review the undo summary.

Undo removes unchanged rows from that import. Entries you edited afterwards are kept, along with entries that were already in your diary. The result tells you which rows were left in place.

Review the affected days after undoing. Calsa will not replace a later choice of daily total or weigh-in with an older one without showing the conflict.
