# How to Convert JSON to SQL Insert Statements Online
When working with APIs, NoSQL exports, or mock data, developers often need to populate relational databases like PostgreSQL, MySQL, or SQLite with JSON data. Manually writing hundreds of `INSERT INTO` statements is tedious and error-prone.
TargetRoot provides a free, instant [JSON to SQL Converter](/tools/data/json-to-sql) that runs entirely on your client machine.

## Why Client-Side JSON to SQL Matters
Most online converters send your sensitive payload to a third-party server. If your JSON contains customer records, private keys, or internal IDs, this poses an immediate data leak risk.
With TargetRoot's [JSON to SQL Tool](/tools/data/json-to-sql):
- **100% Client-Side:** Processing occurs in JavaScript in your browser.
- **No File Size Limitations:** Parse large JSON files directly without server timeouts.
- **Custom Table Names:** Define table names and column types automatically.

## How to Convert JSON to SQL in 3 Steps
1. **Input Your JSON Data:** Paste raw JSON or upload a `.json` file.
2. **Specify the Table Name:** Enter the target database table name (e.g., `users`, `products`).
3. **Generate & Copy SQL:** The tool automatically creates structured `INSERT INTO table_name (col1, col2) VALUES (...);` queries ready to execute.
