The extension also generates syntax for:</p> <ul> <li>DuckDB (SQL joins)</li> <li>PySpark</li> </ul> <p>🛠️ Try it out!<br> I just published the very first version to the VS Code Marketplace, and it is 100% free and open-source.</p> <p>If you work with data in VS Code, I would love for you to try it out and let me know what you think!</p> <p>👉 <strong><a href="https://marketplace.visualstudio.com/items?itemName=trushalprevail.visual-join-builder" rel="noopener noreferrer">Install Visual Join Builder from the VS Code Marketplace</a></strong></p> <p>If you like the project, I would be incredibly grateful if you gave it a ⭐️ on GitHub.
