SQL CREATE TABLE to JSON Schema Converter

Convert SQL database CREATE TABLE declarations into structured JSON schemas and object configurations.

Sync Database Tables and API Schemas

When building full-stack applications, keeping your database tables and API models in sync is critical. Our SQL schema to JSON converter parses CREATE TABLE statements and outputs JSON schemas representing your data models.

Automate Data Models

Avoid rewriting database columns as JSON properties manually. The parser extracts field names, data types, primary keys, and nullability constraints to generate matching JSON objects.

Key Benefits & Features

SQL Syntax Parsing

Recognizes standard data types like INT, VARCHAR, DATETIME, and BOOLEAN.

Required Constraints Mapping

Maps NOT NULL database constraints directly to JSON required fields.

Clean JSON Prettifier

Outputs indented JSON files ready to copy and paste.
