JSON to Drizzle ORM: Generate pgTable, mysqlTable & sqliteTable

Generate Drizzle ORM table definitions from JSON for PostgreSQL, MySQL, and SQLite. Correct column types, import statements, and primaryKey annotations. Free.

What is Drizzle ORM?

Drizzle ORM is a lightweight, TypeScript-native ORM for PostgreSQL, MySQL, and SQLite. Unlike Prisma, schemas are defined in TypeScript code using builder functions (pgTable, mysqlTable, sqliteTable), giving full type inference without a separate schema file.

Why Generate from JSON?

When building API-backed applications, you often have sample JSON from an existing API or database. Generating a Drizzle schema from that sample saves 10–20 minutes of manual mapping per table.

Column Type Mapping per Dialect

  • PostgreSQL: text(), integer(), doublePrecision(), boolean(), timestamp()
  • MySQL: varchar(), int(), double(), tinyint(), datetime()
  • SQLite: text(), integer(), real(), integer() (bool), text() (date)

Frequently Asked Questions

Does the output include the import statement?

Yes. The generated code includes the correct import from drizzle-orm/pg-core, drizzle-orm/mysql-core, or drizzle-orm/sqlite-core.

How do I switch between PostgreSQL, MySQL, and SQLite?

Use the Dialect dropdown in the toolbar. The column functions and import path update automatically.

Can I use the output directly in my project?

Yes. The output is a complete TypeScript module you can paste directly into a new file in your Drizzle project.
