SQL to SQLAlchemy Converter

Convert SQL CREATE TABLE to SQLAlchemy models.

SQL (CREATE TABLE)
SQLAlchemy Model (Python)

How to Use

Paste SQL CREATE TABLE statements into the input panel and the tool will generate equivalent SQLAlchemy model classes in Python. It maps SQL data types to SQLAlchemy column types, preserves primary keys, foreign keys, constraints, and default values. The generated code is ready to use with SQLAlchemy ORM.

Common Use Cases

  • Bootstrapping SQLAlchemy models from an existing database schema export
  • Converting database migration SQL files into Python ORM model definitions
  • Generating type-safe Python models from database design tool exports
  • Speeding up the initial setup of a Flask or FastAPI project with an existing database

Frequently Asked Questions

Which SQL data types are supported?

The tool maps common SQL types including INTEGER, VARCHAR, TEXT, BOOLEAN, FLOAT, DECIMAL, DATE, DATETIME, TIMESTAMP, BLOB, and JSON to their SQLAlchemy equivalents (Integer, String, Text, Boolean, Float, Numeric, Date, DateTime, LargeBinary, JSON).

Are foreign key relationships converted?

Yes. SQL FOREIGN KEY constraints are converted to SQLAlchemy ForeignKey references and relationship() declarations, preserving the referential integrity defined in your schema.

Can I convert multiple CREATE TABLE statements at once?

Yes. Paste all your CREATE TABLE statements together and the tool will generate a separate SQLAlchemy model class for each table, with proper imports and relationships between them.
