🖼️📊 Metadata Extractor (Single)

Reads the generation metadata out of one image: prompts, sampler settings, and the raw block as it was stored.

Inputs

• seed — Which file to take when input_path is a folder. Set its control to increment to walk through them.
• input_path (optional) — A single image file, or a folder of them. Relative paths resolve inside ComfyUI's input folder.
• image_input (optional) — An image already in the workflow. Takes priority over input_path, but carries no metadata of its own — connect a file path instead if you need the settings.
• filter_params (advanced) — Comma-separated keys to pull out, e.g. steps, sampler, seed.

Outputs

• image — The image the metadata came from. A 64×64 black image when nothing could be loaded.
• positive_prompt / negative_prompt — As stored in the file.
• parsed_params_json — Every recognised setting, as indented JSON.
• filtered_params_list — Only the keys from filter_params, one value per line, in the order you asked for them.
• raw_metadata_json — The unparsed metadata block.

Notes

The preview updates when the path or seed changes. Connected inputs show the selected output image after execution. Empty results clear the preview.

Reads png, jpg, jpeg, tiff and tif. Files with no metadata return empty strings and {} rather than failing. Keys absent from the file come back as empty lines in filtered_params_list, so the line positions stay aligned with your filter list.
