How do I convert a SQL query to JSON using this tool?

Paste your SQL query into the input box, or upload a .sql file. The tool executes the query against a mock database and produces a JSON array of objects, preserving column names as keys. You can then download or copy the result. For example, SELECT id, name FROM users becomes [{'id': 1, 'name': 'Alice'}]. Ensure your SQL is valid and includes a terminating semicolon if needed.

Why convert from SQL to JSON?

SQL stores data in relational tables with a fixed schema, while JSON is a lightweight, hierarchical format broadly supported in web and NoSQL ecosystems. Converting SQL to JSON lets you use relational data in REST APIs, document stores like MongoDB, JavaScript applications, or data pipelines where nested objects are more natural. It also reduces the need for ORM mapping when exchanging data between systems.

How does the conversion handle SQL data types and attributes?

The converter maps SQL data types to corresponding JSON types: INT/FLOAT to numbers, VARCHAR/TEXT to strings, BOOLEAN to true/false, and NULL to null. DATETIME/TIMESTAMP values are preserved as ISO-8601 strings to avoid ambiguity. Column names become object keys, and each row is an object in an array. No relational constraints like primary or foreign keys are exported, as JSON has no equivalent.

Is SQL-TO-JSON free to use?

Yes, SQL-TO-JSON on LetsConvert is 100% free with no registration or hidden fees required.

Does this converter work on mobile phones and tablets?

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
