Data and code conversion tools

Convert a T-SQL CREATE TABLE statement to PostgreSQL DDL, or turn a JSON sample into Pydantic v2 models. Deterministic, documented rules, no AI and no uploads.

Deterministic converters for everyday developer chores. Each one lists the rules it applies, what it could not convert, and where those rules come from.

• T-SQL to PostgreSQL DDL Converter

  CREATE TABLE (T-SQL) → PostgreSQL DDL with a documented mapping.

• JSON to Pydantic Models

  JSON sample → Pydantic v2 models.
