Hi Product Hunt! 👋 I'm Artem, a solo founder from Ukraine. ReadyCSV exists because of one awkward moment that kept repeating: an agency or RevOps consultant gets a messy client CSV to import into HubSpot - broken emails, wrong date formats, lifecycle stages that don't match, duplicate contacts. The obvious 2026 move is "paste it into ChatGPT," except you often can't: it's client data under NDA, or GDPR-sensitive, or just not yours to upload anywhere. So ReadyCSV runs the entire preflight in your browser tab: 🔍 Checks the file against real HubSpot import rules (required identity fields, email format & duplicates, date formats, lifecycle/lead-status enums, phone formats, encoding damage, structural CSV problems) 🔧 Lets you apply safe fixes, edit cells, map headers, exclude columns 📤 Exports a cleaned CSV for import + a source-labeled Issue Report you can hand to a client 🔒 No upload, no account, no AI calls, no analytics scripts. Open DevTools → Network tab while you work: your file never leaves the device. The full workflow is free. Paid tiers ($49 one-time Pro / $149/yr Agency with commercial client-work rights) unlock the Excel-friendly export - license keys are verified locally in the browser too, no license server. Honest limits, since trust is the whole point: HubSpot Contacts only for now (Shopify Products is next once its ruleset is ready), ~20MB files, and it flags account-specific things (like custom lifecycle stages) for review rather than pretending to know your HubSpot account. I'd love brutal feedback - especially from anyone who preps client CSVs for a living. What would make this a no-brainer for your workflow?
