Only Product Name is required. Everything else is matched if present, under
any of these headings:
- Purchase Date — or Bought On, Invoice Date. Day-first and month-first
formats are both read, and resolved using your date-format setting.
- Warranty Period (Months) — or Warranty Period, Warranty. Values like
24, 2 years, 6 months and 0.5 are all understood.
- Brand, Model, Serial Numbers,
Purchase Price, Vendor, Receipt No,
Tags, Notes, Category.
Expiry date, pending months and status are not imported — they are
recalculated, so a stale column in your sheet cannot carry a wrong date across.
