Free JSON ↔ SQL Converter
Generate SQL INSERT statements from JSON and vice versa
Convert JSON arrays into SQL INSERT statements or parse SQL queries back to JSON format. Essential for database seeding, data migration, and API development. All processing happens client-side for complete data privacy.
💾 JSON and SQL Integration
JSON is the standard format for API responses and modern data exchange. SQL INSERT statements are used to populate database tables. This tool bridges the gap, allowing you to quickly generate database insertion scripts from JSON data or extract JSON from SQL for testing and documentation.

📚 How to Convert
- 1. Select Mode: Choose JSON to SQL or SQL to JSON conversion
- 2. Set Table Name: Enter your database table name (for JSON to SQL)
- 3. Input Data: Paste your JSON array or SQL INSERT statements
- 4. Generate: Click convert to create the output
- 5. Use Result: Copy the generated SQL or JSON for your project
💡 Sample Transformations
Single Record:
[{"id": 1, "name": "Alice"}] → INSERT INTO users (id, name) VALUES (1, 'Alice');
Multiple Records:
JSON array with multiple objects generates separate INSERT statements
String Escaping:
Automatically escapes single quotes in string values for SQL safety
Reverse Parsing:
INSERT INTO table (col) VALUES ('val'); → [{"col": "val"}]
❓ Frequently Asked Questions
What JSON format is required?
The tool expects a JSON array of objects. Each object represents one database row, with keys as column names and values as the data to insert.
Are NULL values supported?
Yes! JSON null values are converted to SQL NULL in the INSERT statements, ensuring proper database handling.
Can I use different table names?
Absolutely! When converting JSON to SQL, you can specify any table name in the input field. The default is "users" but you can change it to match your schema.
What SQL dialects are supported?
The generated SQL uses standard INSERT syntax compatible with MySQL, PostgreSQL, SQLite, and most other relational databases.
Is my database data private?
Yes! All conversions are performed entirely in your browser using JavaScript. Your database data never leaves your machine or gets sent to any server.
