RowHarbor, a preflight check for Shopify product CSVs

rowharbor.com Observed source

Editorial interest 76/100 Selection signal · not a rating of the site

A browser-based checker that reviews Shopify product CSVs for formatting problems, duplicate variants, and missing update dependencies.

Landing page captured for the 2026-09-07 issue.

Field notes

RowHarbor accepts a Shopify product CSV or a synthetic example and reviews it locally in the browser rather than connecting to a store account. Its stated limits are unusually concrete: UTF-8 files up to 10 MiB and 50,000 data rows, with checks covering variant dependencies, duplicate option combinations, numeric values, status fields, and image URL syntax. A separate comparison workflow is presented for checking edits against an original catalog export.
