JSON to SQL Converter

How to Use the JSON to SQL Converter

Converting JSON data to SQL INSERT statements is simple with our free online tool:

1. Paste your JSON data into the left textarea. The JSON can be a single object or an array of objects.
2. Configure your options: Set the table name, choose your database type (MySQL, PostgreSQL, or SQLite), and optionally include CREATE TABLE statement.
3. Click "Convert to SQL" and your SQL INSERT statements will appear in the right panel.
4. Copy the SQL using the "Copy SQL" button and paste it into your database management tool.

Key Features

Example: Converting JSON to SQL

[
  {
    "id": 1,
    "name": "John Doe",
    "email": "john@example.com",
    "active": true
  },
  {
    "id": 2,
    "name": "Jane Smith",
    "email": "jane@example.com",
    "active": false
  }
]

INSERT INTO my_table (id, name, email, active)
VALUES (1, 'John Doe', 'john@example.com', true);

INSERT INTO my_table (id, name, email, active)
VALUES (2, 'Jane Smith', 'jane@example.com', false);

Why Use Our JSON to SQL Converter?

When working with APIs, data migrations, or database imports, you often receive data in JSON format but need it as SQL INSERT statements. Manual conversion is tedious and error-prone. Our tool automates this process completely:

• Save Time: Convert hundreds of JSON records to SQL in seconds instead of hours of manual work.
• Avoid Errors: Automatic escaping of special characters, proper quoting, and syntax validation.
• Multiple Formats: Support for different JSON structures including arrays, objects, and nested data.
• Database Compatibility: Generate SQL that works with MySQL, PostgreSQL, and SQLite.
• Privacy First: All processing happens locally in your browser - your data stays private.

Supported JSON Formats

Array of Objects (Most Common)

This is the most common format for converting multiple records:

[
  {"name": "Product 1", "price": 29.99},
  {"name": "Product 2", "price": 49.99}
]

Single Object

Convert a single JSON object to an INSERT statement:

{"name": "Product 1", "price": 29.99, "stock": 100}

Common Use Cases

• API Data Import: Import data from REST APIs directly into your database
• Data Migration: Move data between different database systems
• Testing: Quickly generate test data for development
• Backup Restoration: Convert JSON backups back to SQL format
• Data Analysis: Import JSON logs or analytics data into SQL databases

Database Type Differences

Our converter automatically adjusts the SQL syntax based on your selected database:

• MySQL: Uses backticks for identifiers, supports both single and double quotes for strings
• PostgreSQL: Uses double quotes for identifiers, single quotes for strings, proper boolean handling
• SQLite: Simplified syntax compatible with SQLite's limitations

Frequently Asked Questions

Is my data secure?

Yes! All conversion happens entirely in your browser using JavaScript. Your JSON data never leaves your computer and is never sent to any server.

What's the maximum file size?

The tool can handle very large JSON files (several MB). Performance depends on your browser and device, but most files convert instantly.

Can I convert nested JSON?

The tool works best with flat JSON objects. Nested objects will be converted to JSON strings in the SQL output. For complex nested structures, consider flattening your JSON first.

Do I need to sign up?

No! This tool is completely free and requires no registration, signup, or login. Just paste your JSON and convert.

Can I use this for commercial projects?

Absolutely! This tool is free for both personal and commercial use without any restrictions.
