Rowlark - CSV Cleaner & Product Data Cleaning Tool - Sell Project

Try the workflow before buying Open https://rowlark.app/demo, select Whitespace, approve the proposed title trim, and open Change log. The sample shows one approved change while seven other issues remain for review. Download the sample CSV and log without an account. Rowlark keeps duplicate rows and does not invent missing values. Rowlark is a browser-based CSV cleaner for online sellers and catalog freelancers reviewing supplier or client product data before handover. Map columns, inspect duplicate SKUs, missing values, whitespace, prices and URLs, then approve supported whitespace and line-ending corrections. Export the complete CSV with a change log while retaining every original row and column. Files are processed locally in browser memory. Rowlark does not automatically resolve duplicates or guarantee compatibility with a particular marketplace importer. Business model and current stage Rowlark launched in September 2026 and is pre-revenue, with $0 real customer revenue. Anyone can review their own CSV without signing up. Complete corrected CSV and change-log downloads are free for files up to 100 product rows; no rows are silently omitted. Pro adds larger exports and reusable saved presets. Pro costs $29 as a one-time purchase, plus applicable tax, with a seven-day customer refund window. Lemon Squeezy has approved the store and live checkout is enabled. Test-mode purchases, Pro access, refunds and access revocation have been checked; test transactions are not revenue. No established paying customer base or commercial audience is claimed. Operating costs September expenses were $24.20: $14.20 annual domain registration plus $10 allocated from a shared $20/month Resend plan. The monthly equivalent is approximately $11.18 at the current setup. A buyer’s standalone costs may differ; hosting, database and email costs may increase with usage. Included in the sale Rowlark-specific source code, rowlark.app, branding, tests, synthetic fixtures, database migrations, deployment instructions and operating/transfer documentation.

Shared foundation code is included nonexclusively and is also used in other seller products; third-party licenses apply. Other products, personal provider accounts, private credentials and shared recovery keys are excluded. Provider resources will be transferred where supported or recreated under buyer-owned accounts. Domain transfer timing follows registrar rules. The buyer must obtain their own payment-provider approval; seller approval is not guaranteed to transfer.
