Why Convert JSON to SQL?
SQL databases are the backbone of most applications. Converting JSON data to SQL allows you to import data into relational databases, create database schemas from API responses, and build robust data pipelines. This tool ensures proper data type mapping and SQL syntax compliance.
Frequently Asked Questions
What SQL databases are supported?
The generated SQL is compatible with MySQL, PostgreSQL, SQLite, and most other SQL databases. The tool generates standard SQL syntax that works across different database systems.
How does the tool handle different data types?
The tool intelligently maps JSON types to appropriate SQL types: strings become VARCHAR or TEXT, numbers become INT or DECIMAL, booleans become BOOLEAN, and date strings are converted to DATETIME format.
Can I customize the table structure?
Yes, you can configure table names, choose primary keys, enable auto-increment, and control whether CREATE TABLE and INSERT statements are generated separately or together.
What if my JSON has nested objects?
Currently, the tool works best with flat JSON objects. For nested objects, consider flattening them first or using a different approach. The tool will handle simple nested structures by converting them to appropriate SQL types.
Is the generated SQL safe from SQL injection?
Yes, the tool properly escapes string values and handles special characters to prevent SQL injection attacks when the generated SQL is executed.
Can I process large JSON files?
The tool works in the browser, so file size is limited by browser memory. For very large files, consider processing them in chunks or using server-side solutions.
