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

  • Supports up to 50 pairs per node
  • Each pair can have values entered directly or connected from other nodes
  • Dynamic UI shows only active pairs
  • 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. Set the number of pairs you need with pair_count
3. Enter your find patterns and replacements
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

Each find/replace pair has optional input connectors (find_N_input and replace_N_input) that can receive values from other nodes. Connected inputs take priority over widget values.

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
