Replaces your account's category taxonomy used by Purchase Categorisation — both receipt-level and product-level. Review what's currently stored with Export Product Categories.> 🚧 Uploads replace, not merge>> Each upload replaces your entire stored category list — categories missing from the file are removed. Always upload the complete taxonomy.A minimal sample CSV:```csvcategoryName,descriptionFood & Drink,Food and non-alcoholic drink purchasesMedication,Prescription and over-the-counter medicinesToiletries,Personal-care and hygiene products````description is optional. Leave it empty when the category name already says what it means — less input often produces better categorisation. Add one only where the name alone is ambiguous.categoryName` values define the category labels used by categorisation. The service does not case-normalise these labels, so treat the exact uploaded spelling and casing as canonical and use it consistently when handling response values.> 📘 Availability>> Available on Startup plans and above.
