# String Essentials - Custom nodes for ComfyUI
|
|
|
|
Simple string manipulation nodes for ComfyUI (strip/remove text strings, search and replace text strings, preview modified string outputs). Useful for modifying text from LLM outputs (Ollama, Claude.ai, OpenAI ChatGPT), such as prompts or image-to-text description results. No additional Python dependencies or external modules required. Nodes use a small amount of basic Python and Javascript code.

## String Textbox
|
|
A simple multiline textbox for free form text.
|
|
|
|
|
|

### 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
|
|

|
|
- **`remove_extra_spaces`**: Clean up extra spaces after removal
|
|
|
|
## String Replace
|
|
Replaces text strings with new strings (replace/swap words etc.). Each line should contain a search and replace pair separated by the replacement_delimiter (default is double colon `::`). Example to replace dog with cat `dog::cat`. Supports mulitple string replacements, just add one replacement per line. You can also remove strings with this node just leave the right side of the delimiter blank.
