ComfyUI Multi-Replace

A ComfyUI custom node package for creating and applying multiple find/replace pairs to text.

Features

• Find/Replace Pairs Node: Create an arbitrary number of find/replace pairs

  • Starts with one pair, click "➕ Add Pair" button to add more
  • Right-click menu also provides Add/Remove pair options
  • All pairs are input connectors for easy connection from other nodes
  • Outputs: pairs object, JSON, and CSV formats

• Text Replacer Node: Apply find/replace pairs to text

  • Accepts pairs from the FindReplacePairs node
  • Supports regular expressions
  • Case-sensitive/insensitive matching
  • Replace all or first occurrence only
  • Outputs: modified text, pairs passthrough (for chaining), changes log, and replacement count

Installation

1. Clone or copy this folder to your ComfyUI custom_nodes directory:

   cd ComfyUI/custom_nodes
   git clone <repo-url> comfyui-multi-replace
   

2. Restart ComfyUI

Usage

Basic Usage

1. Add a Find/Replace Pairs node
2. Enter your find pattern and replacement in the first pair
3. Click ➕ Add Pair to add more pairs as needed
4. Connect the pairs output to a Text Replacer node
5. Enter or connect your input text
6. Get the modified text from the result output

Connecting Dynamic Values

All find/replace pairs are input connectors, making it easy to connect values from other nodes (e.g., text prompts, primitives, or other string outputs).

Chaining Replacers

The Text Replacer node passes through the pairs object, allowing you to chain multiple replacers or use the same pairs set multiple times.

Output Formats

Find/Replace Pairs outputs:

• pairs - Internal pairs object for use with TextReplacer
• json_output - JSON array of pairs: [{"find": "...", "replace": "...", "index": 1}, ...]
• csv_output - CSV format: find,replace per line

Text Replacer outputs:

• result - The text after all replacements
• pairs_passthrough - The pairs object (for chaining)
• changes_log - Human-readable log of changes made
• replacement_count - Total number of replacements performed
