What is a SQL to JSON Converter?

A SQL to JSON Converter is a free online tool that parses SQL statements (CREATE TABLE, INSERT INTO) and converts the data within them into clean JSON format. It is the reverse of JSON-to-SQL conversion — taking structured database data and transforming it into the JSON format used by modern web applications, APIs, and NoSQL databases.

Why convert SQL to JSON?

Migrating data from relational databases to NoSQL systems, creating API mock data from existing database records, or generating JSON fixtures for testing — all require converting SQL data to JSON. This tool parses your SQL INSERT statements, extracts the data, and produces a clean JSON array of objects with column names as keys.

How to use the converter?

Paste your SQL INSERT statements. The converter parses the SQL syntax, extracts column names and values, handles different SQL data types and string escaping, and produces a JSON array where each INSERT row becomes a JSON object. It supports MySQL, PostgreSQL, SQLite, and SQL Server syntax variations.
