SchemaSnap

SchemaSnap is a web app (with optional desktop connector) that turns messy spreadsheets and Airtable-like tables into a clean, validated data model you can actually build on. Users upload a CSV/Excel or connect Google Sheets, and SchemaSnap profiles columns, detects types, finds duplicates, flags risky free-text fields, and proposes a normalized schema with constraints. Then it generates ready-to-use backends for popular no-code tools (Xano, Supabase) plus exports: Postgres DDL, JSON Schema, and API contracts. The brutal truth: most “no-code apps” fail because the data layer is garbage from day one—SchemaSnap fixes that before you waste weeks building workflows on bad tables. It also produces migration plans when your sheet changes, so you don’t silently break automations. Pricing is per project and per connector, aimed at teams building internal tools and lightweight SaaS.
