The only problem I can foresee is if the edits you are making are in the first field of the note. If that field changes, Anki won’t be able to match the notes to each other during the update process (see the Importing Text Files link). Then you will end up creating new near-duplicate notes (which will then create cards without your review history). To avoid that, make sure the first field is a different field or add a unique ID number (see the Exporting link).
