Learn how areas, material items and compatible purchase groups relate. Saving, JSON backups and imports each have a different purpose; choose the one that matches what you want to keep or move.
Read the PDF and CSV guide before sharing a shopping list. Use a JSON backup when you need the editable project rather than a reading or spreadsheet copy.
