• modifiedAt: preferably do not edit manually; if needed, keep the exported ISO-8601 value

How import works

• Import is always additive and never replaces existing lists

• Bukon creates a preview before import

• The preview shows importable books, detected duplicates, and books that would be imported as manual entries

• You can import all importable books or only a selection

• If an Open Library key is present, Bukon loads extra details such as description and cover

• If no Open Library key is present, Bukon tries to find a unique Open Library match via ISBN

• If no unique match is found, the book is imported as a manual entry

• Duplicates are detected by Open Library ID and ISBN

• Invalid values show an error with row, column, and book context
