Formatted String

(ComfyUI workflow included)

Creates a string that contains placeholder variables and replaces them with their respective values. Uses python str.format() internally, see Python - Format String Syntax .

• You can use {a:.2f} to round off a float to 2 decimals.
• You can use {a:05d} to pad up to 5 leading zeros to fit with comfys filename suffix ComfyUI_00001_.png.
• If you want to write { } within your strings (e.g. for JSONs) you have to double them: {{ }}.

Also applies search & replace (S&R) syntax such as %date:yyyy-MM-dd hh:mm:ss% and %KSampler.seed%. Thus you can also use it as a GET-node. Note that "search & replace" takes place in Javascript context and runs before node execution.
