How to Use the SQL to JSON Converter
This SQL to JSON converter transforms SQL statements into JSON format. In "Schema Mode", enter a CREATE TABLE statement to output column names, data types, and constraints in JSON Schema format. In "Data Mode", enter INSERT INTO statements to output the data as a JSON array of objects. SQL types are automatically mapped to JSON types (VARCHAR to string, INT to number, BOOLEAN to boolean, etc.), and constraints like PRIMARY KEY, NOT NULL, and DEFAULT values are included.
