Free SQL to JSON Converter Online — No Signup Required

SQL-to-JSON conversion bridges the gap between relational database outputs and JSON-based APIs, front-end applications, and data pipelines. When you run a SELECT query in a database client, the result is a table of rows and columns — but REST APIs, React components, and most modern tools expect JSON objects. This converter takes SQL result output (tab-separated or comma-separated rows, with column headers) and produces a JSON array of objects where each row becomes an object with column names as keys.

The tool also handles CREATE TABLE statements — extracting column names and types to produce a JSON Schema or a sample JSON object with the correct field names. This is useful when documenting APIs, seeding test data, or generating TypeScript interfaces from an existing database schema. Supported input formats include CSV-style query results, pipe-delimited output (common in MySQL CLI), and CREATE TABLE DDL statements.
