How are MySQL data types determined?

The tool maps JSON types to MySQL types: strings to VARCHAR/TEXT, numbers to INT/BIGINT/FLOAT/DECIMAL, booleans to TINYINT, and arrays to JSON type.

Can I customize the table name?

Yes, you can specify a custom table name for the generated CREATE TABLE statement.

Does it handle nested JSON objects?

Nested objects are either stored as JSON type columns or can be flattened into separate tables depending on configuration.

About JSON to MySQL

This tool helps you quickly convert JSON data to MySQL CREATE TABLE statements. In backend development, we often need to design database table structures based on API-returned JSON data. Writing these SQL statements manually is tedious and error-prone.

Simply paste JSON data and the tool will automatically analyze the JSON structure and generate corresponding MySQL CREATE TABLE statements. Supports automatic field type inference, nested object handling, and index suggestions.
