SQL to DBML

How it works

1. Paste your SQL schema into the editor (PostgreSQL, MySQL, SQLite, SQL Server, Oracle…).
2. The diagram renders instantly so you can confirm the tables and relations.
3. Click Export → DBML and copy the result.
4. Paste it into dbdiagram.io or any DBML-based workflow.

Example

This SQL:

CREATE TABLE users (
  id SERIAL PRIMARY KEY,
  email TEXT UNIQUE
);
CREATE TABLE posts (
  id SERIAL PRIMARY KEY,
  user_id INT REFERENCES users(id)
);

…exports as this DBML:

Table users {
  id serial [pk]
  email text [unique]
}
Table posts {
  id serial [pk]
  user_id int
}
Ref: posts.user_id > users.id

Copy it from Export → DBML. Try it with your own →

Why use it

• Private: everything runs in your browser — nothing is uploaded or stored on a server.
• dbdiagram.io-ready DBML output.
• Verify visually — see the live diagram before you copy.
• Free & open source — no account, no sign-up.

FAQ

How do I convert SQL to DBML?

Paste your CREATE TABLE statements, then click Export → DBML and copy the output. Tables become Table blocks and foreign keys become Ref: lines.

Is this a free dbdiagram importer?

Yes — convert SQL to DBML for free and paste it straight into dbdiagram.io, with no account.

Is my schema uploaded anywhere?

No. Everything runs locally in your browser — your schema is never uploaded to or stored on any server.

Is it free?

Yes. It is completely free and open source, with no account or sign-up required.
