Workflow JSON comparison

What this tool does

Both sides are parsed, canonically serialised with sorted keys, and compared. A line-by-line visual diff is out of scope for this version and would be easy to get misleadingly wrong on huge graphs.

How to use it

1. Paste left and right JSON.
2. Read equal: true or false.
3. If they differ, use a dedicated diff editor for line detail.

This tool processes files and text locally in your browser. Your content is not uploaded or stored by this site.

ConvertPass does not include your input in analytics, URLs, or error reports. Encoding: UTF-8. Limit: 2 MB per side (2.00 MB).

Limitations

• Key sorting ignores original key order.
• Numeric noise in floats can make equal graphs look different.

Example

Two exports of the same graph with different key order

{"equal": true}

Troubleshooting

They look the same but equal is false

Seeds, widget values, or last-even-minor-position fields often differ. Format both, then compare in an editor.

FAQ

Why not a red/green diff?

A naive string diff on minified JSON is unreadable, and a structural diff for ComfyUI graphs is a product of its own. Equality is honest for a first tool.

Are comments ignored?

JSON has no comments. JSONC will fail to parse.

Does this upload workflows?

No.

Can I compare prompt chunks?

Yes. Paste any two JSON documents, including prompt graphs.
