How to Convert Go to SQL - Step by Step Guide

Step 1

Input Your Go Struct Slice

Paste your Go slice of structs that represents your database records. Perfect for generating SQL DDL and INSERT statements:

•
Paste Go slice: Copy your []StructType{...} code directly
•
Upload a file: Load Go code from your test fixtures or seed data
•
Try samples: Click sample buttons to see different database structures

Example: Go Struct Slice for Users Table

Here's a typical Go struct slice representing database records:

[]User{
    {
        ID: 1,
        Username: "john_doe",
        Email: "[email protected]",
        Age: 28,
        Active: true,
    },
    {
        ID: 2,
        Username: "jane_smith",
        Email: "[email protected]",
        Age: 32,
        Active: true,
    },
}
Step 2

Automatic SQL Schema Generation

The converter automatically analyzes your Go structs and generates CREATE TABLE and INSERT statements:

•
Type mapping: Converts Go types to appropriate SQL types (int→INTEGER, string→VARCHAR)
•
CREATE TABLE: Generates schema with proper column definitions and data types
•
INSERT statements: Creates INSERT queries for each struct in your slice
•
Value escaping: Properly escapes strings and handles special characters for SQL safety

Example: Generated SQL Output

The Go struct slice converts to this SQL schema and data:

CREATE TABLE User (
    ID INTEGER PRIMARY KEY,
    Username VARCHAR(255),
    Email VARCHAR(255),
    Age INTEGER,
    Active BOOLEAN
);

INSERT INTO User (ID, Username, Email, Age, Active)
VALUES
    (1, 'john_doe', '[email protected]', 28, true),
    (2, 'jane_smith', '[email protected]', 32, true);
Step 3

Customize and Export SQL

Fine-tune your SQL output and export it for use in your database:

•
Toggle INSERTs: Choose whether to include INSERT statements or just CREATE TABLE
•
Copy to clipboard: One-click copy to paste into your database client
•
Download as .sql: Save as SQL file for migrations or seed scripts
•
Ready for all databases: Works with PostgreSQL, MySQL, SQLite, and more

Frequently Asked Questions

What SQL dialect is generated?

The converter generates standard SQL that works with PostgreSQL, MySQL, SQLite, and most SQL databases. It uses common types like INTEGER, VARCHAR, TEXT, DECIMAL, and BOOLEAN.

How are Go types mapped to SQL types?

int → INTEGER, float64 → DECIMAL(10,2), string → VARCHAR(255) or TEXT, bool → BOOLEAN. The converter intelligently chooses SQL types based on Go values and field names.

Can I generate just CREATE TABLE without INSERTs?

Yes! Toggle the "Generate INSERTs" button to control whether INSERT statements are included. Great for generating schema-only migrations or database documentation.

Does it handle Go struct tags for database columns?

Yes! If your Go structs have db or json tags, the converter uses those for column names. Otherwise, it converts Go field names (like UserName) to snake_case SQL columns (user_name).

Is this free?

Yes, completely free with unlimited conversions! Perfect for database migrations, test data generation, documenting your database schema, or creating seed scripts for development environments.
