How do I convert a JSON file to SQL INSERT statements?

Open the converter, upload your .json file, choose SQL flavor (MySQL, PostgreSQL, SQL Server), and set table name. The tool parses each JSON object into a row. Arrays become either comma-separated values, JSON columns, or linked child tables depending on your 'array handling' setting. Click Convert, then download the .sql script.

Why convert JSON to SQL instead of using JSON directly in an app?

SQL enables relational queries, ACID transactions, and joins across large datasets. JSON documents are self-contained but nested structures lead to repetitive data and slow full-scan filtering. Converting to SQL lets you use indexing and report tools, and reduces storage size when normalized into tables.

How does the JSON-to-SQL conversion preserve data types and nested structures?

The converter maps JSON primitives to SQL types: strings to VARCHAR/TEXT, numbers to INT/DECIMAL, booleans to BOOLEAN/BIT, null remains NULL. Nested objects become either an inline JSON column (PostgreSQL jsonb) or separate related tables via detected foreign keys. Arrays are flattened to one-to-many tables or stored as JSON, preserving the original values without loss.

Is JSON-TO-SQL free to use?

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

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Yes! JSON-TO-SQL works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

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