No. The converter parses the SQL CREATE TABLE syntax statically in your browser and transforms it directly into TypeScript Zod schema code without needing any database connection.
How are nullable columns handled?
Columns without NOT NULL or PRIMARY KEY constraints in SQL are automatically generated with .nullable() in Zod to mirror relational database semantics.
Is my schema data kept private?
Yes. All processing happens 100% client-side in your local browser sandbox. No SQL statements or schema definitions are transmitted over the internet.
