SaveText - ComfyUI Built-in Node Documentation

The Save Text node writes text content to a file in the output directory. It supports saving in .txt, .csv, .md, or .json format, and automatically handles JSON pretty-printing when valid JSON is provided.

Inputs

Parameter	Description	Data Type	Required	Range
`text`	The text content to save to a file. This input must be connected from another node.	STRING	Yes	-
`filename_prefix`	Prefix for the output filename. A 5-digit counter is appended to prevent overwriting existing files (default: “ComfyUI”).	STRING	No	-
`format`	The file format to save the text as (default: “txt”). When “json” is selected, valid JSON text is pretty-printed with 2-space indentation; otherwise, the text is saved as-is.	COMBO	No	`"txt"` `"csv"` `"md"` `"json"`

Notes

text is a forced input and must be connected to another node; it cannot be typed directly.
The saved file is named <filename_prefix>_<5-digit counter>.<extension> and is written into the ComfyUI output directory (in a subfolder derived from the prefix).
Selecting the "json" format attempts to parse the text as JSON. If parsing succeeds, the content is written pretty-printed with 2-space indentation; if parsing fails, the raw text is written unchanged.
The node reports the saved file back to the interface so it appears with the other generated output files.

Outputs

Output Name	Description	Data Type
