Stop Writing Laravel Migrations by Hand. Convert Raw SQL Instantly! 🚀

If you are migrating a legacy application to Laravel, setting up local databases from existing production SQL dumps, or converting raw DDL to PHP schemas—you know the pain.

Translating raw CREATE TABLE statements into Laravel's fluent Blueprint migrations by hand is tedious, slow, and highly prone to syntax typos.

To solve this developer bottleneck, we built a 100% local, instant SQL Schema to Laravel Migration Converter on tools.kandz.me.

🧠 How It Works Under the Hood

This converter is built strictly on browser-first Web APIs. It parses database layouts and translates schemas on the fly without ever exposing your sensitive schema models to a backend database:

1. DDL Pattern-Matching Parser

Our core parsing pipeline reads the raw SQL string line-by-line using a regex DDL tokenizer.

• Table Extraction: It identifies database table labels using the CREATE TABLE matching syntax:

  const tableMatch = rawSql.match(/CREATE\s+TABLE\s+`?([a-zA-Z0-9_]+)`?/i);

• Type Mapping Dictionary: It loops through column declarations, strips backticks, and maps common SQL database types (and constraints) directly into Laravel’s corresponding schema methods:
  • VARCHAR(255) NOT NULL UNIQUE ➔ $table->string('column', 255)->unique();
  • BIGINT AUTO_INCREMENT PRIMARY KEY ➔ $table->id();
  • TINYINT(1) or BOOLEAN ➔ $table->boolean('column');

2. Automatic Modifier Chaining

Standard database modifiers like DEFAULT values or nullability are captured by scanning line contexts. If NOT NULL is absent, the parser automatically appends the fluent nullable chain:

$table->string('bio')->nullable();

It also checks for typical timestamp fields and appends $table->timestamps(); automatically if missing, ensuring compliance with modern Laravel standards.

3. 100% Client-Side Privacy Sandbox

Database schemas and index names represent the blueprint of your system's architecture—uploading DDL files to external servers introduces huge security risks.

Our converter uses 100% local browser execution. The entire parsing loop and PHP class generation run exclusively inside your browser's private memory thread. Your schema definitions never leave your device.

Let me know your feedback in the comments, and if there are specific complex custom database constraints (like foreign key lookups) you would like me to add support for next!

The browser-first approach is a sensible fit for schema conversion, especially when production DDL can contain sensitive table and index names. The examples for mapping BIGINT AUTO_INCREMENT PRIMARY KEY to $table->id() and inferring nullable() from a missing NOT NULL make the basic workflow easy to understand, but regex line parsing will get fragile around multi-line constraints, quoted defaults, and dialect-specific types. I'd treat generated migrations as a strong first draft and add a clear warning when the parser encounters unsupported foreign keys or composite indexes; preserving uncertainty is safer than silently producing.

Thank you for this excellent feedback! You hit the nail on the head—preserving uncertainty is indeed far safer than silently producing output.

I designed this converter to provide a strong first draft, but your suggestion to append clear warning comments when the parser encounters unsupported foreign keys or composite indexes is spot on. I am planning to add these automatic '// TODO' warnings in the next update to prevent silent migration crashes down the line.

I really appreciate you taking the time to share this insight!
