Find product pairs with support, confidence and lift. Revenue is supplied historical line-item amounts, in one currency. Repeated lines in the same order sum; orders count distinctly per customer. Dates must be ISO calendar dates. Positive spend is required for concentration. RFM ties receive equal scores using midrank bands; no predictions or causal claims. Basket analysis deduplicates products per order and examines pairs, at most 100 products and 2,000 baskets.

Prepare the input

Find product pairs with support, confidence and lift.

CSV, TSV and arrays of scalar JSON objects are supported. Identifiers stay text. Empty cells are missing by default; add special missing tokens only if their meaning is certain. Use the sample to inspect the exact workflow.

Keep the useful output

Review the summary and result records. Transformation tools retain separate change, rejected-record or diagnostics datasets where relevant. Choose the dataset before exporting; a report and a cleaned dataset serve different purposes.

CSV exports protect formula-like text. JSON keeps data portable without making an Excel workbook. Reports and editable backups may contain private source values; download only what you intend to share. No automatic account storage or server processing is used.
