Saving a workflow for ComfyUI

File ▸ Save workflow for ComfyUI… writes the graph as an ordinary ComfyUI workflow, a .json file that ComfyUI opens. It is clean: explanations, notes and descriptions stay in the project, not in this file. To keep them, also save a project file.

#How to save

1. File ▸ Save workflow for ComfyUI… (Ctrl+E), Export on the toolbar, or Save workflow… after a build.
2. The app checks the graph first. If it finds problems, it asks: "The workflow has 3 issues. ComfyUI may not run it as it is. Open the check to fix them, or save anyway." It lists them. Choose Open check (fix first), Save anyway or Cancel.
3. If a field looks like a key or a token, it asks: "1 field looks like a key or token. Whoever gets the file can read these values. Save without them (the fields stay empty in the file), or save as it is." Choose Save without these values or Save as it is.
4. In the dialog Save the workflow for ComfyUI, choose the place and the name, then Save. The app suggests the title of the graph with .json, and adds .json if the name you type has none.
5. "Workflow saved for ComfyUI." The card Run it in ComfyUI opens and says how to run the file. See Running the result in ComfyUI.

Every save of a workflow asks where to write it: the app does not write over the workflow you opened by itself. Whether the dialog asks before it replaces a file that already exists depends on the file dialog of your system.

#What goes into the file

• Every node with its fields, every link, the groups, the subgraphs, the node names and positions.
• A workflow you opened goes back exactly as it was, except for what you changed.
• Notes on the canvas, colours, bypassed and muted nodes are kept, so ComfyUI shows them too.
• A workflow opened from the API format is saved as an ordinary canvas workflow, with the positions the app gave it. The app does not save in the API format.
• The format is the one the graph came in (1, or the older 0.4); a new graph is written so ComfyUI can open it.

#What the app warns about after saving

• "These fields have no value and no default, so ComfyUI will ask for them: …" Set them in ComfyUI or here and save again.
• "The app does not know the exact order of this node's fields, so these values are not written to the saved workflow." Set those values in ComfyUI.

#What can go wrong

• "The workflow file could not be written." / "This folder cannot be written to. Pick another folder." / "There is no free space on the disk. Free some space or pick another disk." / "This file is protected from writing. Choose another name, or allow writing to it in its properties."
• The file is written whole or not at all: if writing stops halfway, the old file stays as it was.
