About this tool

When importing massive datasets into database servers like PostgreSQL or Supabase, developers waste hours mapping data schema parameters manually. This utility acts as an automatic structural translator. It recursively traverses your JSON object keys to identify matching structures, inferring data types with precision.

Numbers are converted to INTEGER or NUMERIC, boolean flags to BOOLEAN, strings mapping to standard characters, and nested objects/arrays to Postgres JSONB parameters automatically. This local generation minimizes the risk of credentials leaking over third-party APIs.
