HubSpot's built-in code editor has no formatting tools. You paste in a template, the indentation is wrong. You write a module, the HubL tags are inconsistent. You inherit a codebase from another developer, and every file has different spacing conventions. There is no "Format Document" shortcut, no Prettier integration, no way to clean up code without doing it manually line by line. For HubSpot developers who spend hours in the Design Manager, this is a daily frustration.
The HubL Code Formatter is a browser extension that adds a format button directly to HubSpot's code editor. One click and your HubL, HTML, and CSS are formatted with consistent indentation, proper tag alignment, and clean structure. Available for Chrome and Firefox.
Why HubSpot Developers Need a HubL Formatter
Clean code is not aesthetic preference. It is a maintenance requirement. When HubL tags are inconsistently formatted, bugs hide in plain sight. When indentation is wrong, template logic is harder to follow. When every file in a theme uses different conventions, onboarding a new developer takes twice as long. A HubL code formatter browser extension solves this at the source, inside the editor where the work happens.
How It Works
Install the extension. Open any file in HubSpot's Design Manager code editor. Click the format button that appears in the editor toolbar. Your code is instantly reformatted with consistent indentation, aligned HubL tags, and clean HTML structure. The formatter understands HubL syntax, so it handles {% if %}, {% for %}, {% block %}, and other HubL-specific tags correctly, not just as generic HTML.
What Gets Formatted
HubL templates: Proper indentation of HubL control structures, consistent spacing around tags, clean nesting of conditional blocks and loops.
HTML: Standard HTML formatting with proper tag indentation, attribute alignment, and self-closing tag handling.
CSS: Consistent property indentation, selector formatting, and declaration alignment.
Built for the HubSpot Developer Workflow
The formatter runs entirely in the browser. Your code never leaves your machine or gets sent to an external server. It integrates directly with HubSpot's Monaco-based code editor, so the formatting action feels native. No copy-pasting into an external tool and back. No configuration files. No setup. Install, open a file, click format.
