OVERVIEW Shopify catalogue preparation that works on your file, not your store — no API key, no OAuth, no store access. Validate a product CSV header against Shopify's current column names, build valid handles, count variants before you hit the ceiling and check metafield keys; with a licence, reprice in bulk and estimate payouts.

KEY CAPABILITIES • product_csv_check — the header row against current Shopify columns: missing, renamed and unrecognised • url_handle — a valid, unique Shopify handle from a product title • variant_matrix — the variant count a set of options produces, with the limits flagged • metafield_key_check — namespace and key validity with a suggested fix • Licence: bulk_price_change (percentage, then flat amount, then rounding — in that stated order) + payout_estimate (net payout after fees and refunds; pass your own rates)

USE CASES • Fix a CSV template copied from an out-of-date guide before the import fails • Decide whether a catalogue needs splitting into several products • Reprice a catalogue before export

WHO THIS IS FOR Merchants and agencies preparing Shopify imports, and the agents that build product files for them.
