Visualize schemas from real inputs
Paste SQL or load SQLite, CSV, JSON, and Excel files to generate an ER diagram in the browser.
Database diagramsbefore the tool feels overwhelming
GraphMyDB turns SQL, SQLite, CSV, JSON, and Excel into readable ER diagrams. Inspect relationships, compare schema versions, preview migrations, export visuals, and collaborate in live co-op sessions from one browser-based workspace.
No forced signup for local schema work
Sample-first onboarding instead of an empty tool wall
Hosted features only when collaboration or billing is needed

Core capabilities
What you can do with GraphMyDB
GraphMyDB is built for reading, understanding, and sharing database structure faster, whether you start from SQL, files, or an existing schema snapshot.
Inspect tables, keys, and relationships
Review columns, constraints, and foreign-key links in an interactive ER view instead of scanning raw DDL.
Export, compare, and collaborate
Export diagrams and schema formats, compare versions, preview migrations, and run invite-code co-op sessions.
Product details
Built to help teams understand schema structure faster
Browser-first workflow
Most schema parsing and diagram work happens locally in the browser before hosted features are needed.
Migration and review support
Use compare and migration tools to understand schema changes before applying them.
Collaboration when needed
Start hosted co-op sessions only when you want live collaboration, not as a requirement for basic use.
How it works
From SQL file to ER diagram in seconds
GraphMyDB generates interactive entity-relationship diagrams from your database schema. No server upload needed — parsing runs locally in your browser.
1
Load your schema
Paste SQL, upload a .sql dump, drag in a SQLite .db, CSV, JSON, or Excel file. GraphMyDB parses it locally in your browser.
2
Explore the ER diagram
Tables, columns, primary keys, foreign keys, and indexes appear as interactive nodes. Click any table to focus on its relationships.
3
Compare, export, or collaborate
Diff old vs new schemas, export as PNG/SVG/SQL/Excel, or start a live co-op session with an invite code.
Supported databases & formats
Visualize MySQL, PostgreSQL, SQLite, CSV, Excel, and JSON schemas
GraphMyDB supports the most common database dialects and data formats. Each tool page is optimized for its specific syntax and features.
MySQL
CREATE TABLE, ALTER TABLE, AUTO_INCREMENT, FOREIGN KEY, indexes
Open MySQL tool →PostgreSQL
SERIAL, BIGSERIAL, CREATE INDEX, GENERATED columns, ALTER COLUMN
Open PostgreSQL tool →SQLite
AUTOINCREMENT, IF NOT EXISTS, .db file import and export
Open SQLite tool →CSV / TSV
Auto-detected types and relationships, any file size
Open CSV / TSV tool →Excel
Each sheet becomes a table with column headers
Open Excel tool →JSON
JSON schema visualization with inferred structure
Open JSON tool →Why GraphMyDB
How GraphMyDB compares to other database diagram tools
GraphMyDB is a relational database schema visualizer — not a graph database. If you need to turn SQL schemas, CSV data, or Excel files into ER diagrams, GraphMyDB is the tool for that.
| Feature | GraphMyDB | Typical alternatives |
|---|---|---|
| Browser-based, no install | Yes | Varies |
| MySQL, PostgreSQL, SQLite DDL | Yes | Often limited |
| CSV/Excel/JSON to ER diagram | Yes | Rare |
| SQLite .db file import | Yes | Rare |
| Live co-op with invite codes | Yes | Rare |
| Schema diff & migration preview | Yes | Some |
| Export PNG, SVG, SQL, Excel, SQLite | Yes | Limited |
| VS Code extension | Yes | Some |
| Free for local use, no sign-up | Yes | Often requires account |
Looking for a database schema visualizer instead of a graph database? GraphMyDB is purpose-built for SQL ER diagrams, not graph queries. Try the MySQL visualizer, PostgreSQL ERD generator, or SQLite diagram tool.
Frequently asked questions
Common questions about the product
What is GraphMyDB?
GraphMyDB is a free, browser-based database visualizer that turns SQL, CSV, JSON, Excel, and SQLite inputs into interactive ER diagrams. No installation needed — everything runs in your browser.
Do I need an account to use GraphMyDB?
No. Local schema parsing, visualization, and diagram export can all be used without an account. Accounts are only needed for hosted co-op sessions, export credits, and Pro features.
Can I collaborate live on database diagrams?
Yes. Load a schema, start a co-op session, and invite collaborators with a room code. Each participant sees the live shared code while keeping independent diagram navigation.
Which SQL dialects does GraphMyDB support?
GraphMyDB supports MySQL, PostgreSQL, and SQLite DDL including CREATE TABLE, ALTER TABLE, FOREIGN KEY, INDEX, SERIAL, AUTO_INCREMENT, AUTOINCREMENT, and all common SQL statements.
What file formats can I upload?
You can upload SQL files (.sql), SQLite databases (.db, .sqlite, .sqlite3), CSV/TSV files of any size, JSON schema files (.json), and Excel spreadsheets (.xlsx, .xls). All parsing happens locally in your browser.
Is my data private?
Yes. GraphMyDB parses files locally in your browser by default and does not upload schemas to any server. Co-op sessions use encrypted peer connections for live sync without permanent storage.
Can I compare two database schemas?
Yes. Use the Compare tab for full snapshot-to-snapshot diff, or the Migration tab for base-plus-migration analysis. Changes are shown visually and as a human-readable changelog.
Is GraphMyDB a graph database?
No. GraphMyDB is a relational database schema visualizer for SQL, CSV, and Excel — it generates ER diagrams from DDL. It is not a graph database engine. If you need to visualize SQL tables, columns, and foreign keys, GraphMyDB is the right tool.
What export formats are available?
You can export diagrams as PNG or SVG, and schemas as SQL DDL, CSV, JSON, Excel (.xlsx), or a generated SQLite .db file. All from the Export tab in the workspace.
Is there a VS Code extension?
Yes. The GraphMyDB VS Code extension lets you visualize schemas, compare database versions, load SQLite files, and run co-op sessions directly from your editor.
Can I upload large CSV files?
Yes. Files of any size are supported. Large CSVs are automatically sampled — the first ~2,000 rows are read for fast schema inference without freezing your browser.
