Easy to use string manipulation nodes for ComfyUI (strip/remove multiple text strings or search and replace text strings). Particularly useful for modifying text from LLM outputs (Ollama, Claude.ai, OpenAI ChatGPT), such as prompts or image-to-text description results. Nodes will be located under standard Add Node > utils menu.

Features

Remove or replace text, words, numbers in input strings
Handle multi-word strings (partial sentences/phrases)
Case-sensitive/insensitive matching
Whole string matching option

String Strip Node

Removes specified strings from input text. Each line should contain the string to be searched. The string can contain multiple words. To match individual words/strings place on separate lines.

Inputs

input_string: The string or text to process
strings_to_remove: List of strings to remove (one per line)
match_case: Enable/disable case-sensitive matching (default: disabled)
match_whole_string: Ensure only exact matches are removed (default: enabled)
remove_extra_spaces: Clean up extra spaces after removal (default: enabled)

String Replace Node

Replaces text strings with new strings. Each line should contain a search and replace pair separated by the replacement_delimiter (default is double colon ::).

Inputs

input_string: The string or text to process
replacement_pairs: List of search::replace pairs (one per line)
replacement_delimiter: Character(s) that separate search and replace strings (default: ::)
match_case: Enable/disable case-sensitive matching (default: disabled)
match_whole_string: Ensure only exact matches are replaced (default: disabled)
