ComfyUI Workflow Importer

Repository: https://github.com/Matthew-X/comfyui-workflow_importer

Import complete ComfyUI workflows directly from images that contain embedded workflow metadata.

Status: Experimental — still in testing and may have some unforeseen issues.

This extension adds:

• A toolbar button + dialog for drag-and-drop import of images.
• A keyboard shortcut (Ctrl+Shift+I) to open the import dialog.

Features

• Import one or multiple images at once; each image opens in a new workflow tab.
• Supports common ComfyUI metadata keys for both workflow graphs and API prompt formats.
• Detects images that only contain Automatic1111 parameters and reports a clear error.
• Works with both new-style ComfyUI UI menu (0.2.0+) and legacy menu:
  • New-style: adds an Import button group before Settings.
  • Legacy: adds an Import button next to the Manager button (when present).

Example UI (may differ slightly depending on theme/ComfyUI version):

Installation

Using Git (manual install)

1. Navigate to your ComfyUI/custom_nodes directory:

   cd /path/to/ComfyUI/custom_nodes
   

2. Clone this repository:

   git clone https://github.com/Matthew-X/comfyui-workflow_importer.git
   

   (This repo: https://github.com/Matthew-X/comfyui-workflow_importer)
3. Restart ComfyUI.

On startup, ComfyUI will detect the Python package and load the web extension from this repository's web folder.

Via ComfyUI-Manager (when listed)

Once this repository is added to the ComfyUI-Manager extension list, you will be able to:

1. Open Manager inside ComfyUI.
2. Go to the Available (or Extensions) tab.
3. Search for "Workflow Importer" or "Comfy.WorkflowImporter".
4. Install the extension and Restart ComfyUI.

Until it appears in the Manager list, use the Git/manual install method above.

Usage

After installation and restart:

1. Open the Import dialog

   • Click the Import button added to the top toolbar, or
   • Press Ctrl+Shift+I (on macOS: Cmd+Shift+I).

2. Import workflow(s) from images

   • Drag & drop one or more PNG/WEBP/JPEG images into the dialog, or click the drop area to pick files.
   • The extension will attempt to read ComfyUI workflow metadata from each image.
   • Each successfully parsed workflow is opened as a new workflow tab.

3. Status and errors

   • A status area in the dialog shows progress and results.
   • If an image contains no ComfyUI workflow/prompt metadata, or only Automatic1111 parameters, a clear message is shown.

Compatibility & Requirements

• Tested with recent ComfyUI builds (0.2.0+), supporting both new and legacy menu layouts.
• No additional Python dependencies beyond a standard ComfyUI installation (Pillow and aiohttp are already bundled with ComfyUI).
• Should work with images saved by various ComfyUI versions that embed workflow/prompt metadata.

If you encounter issues with a specific image or ComfyUI version, please open an issue and, if possible, attach a sample image (or describe how it was created).
