• Toggle to enable/disable negative prompt column
• Outputs positive prompt, negative prompt, and total row count
• Navigate through rows using an index parameter

Sample Workflow

Installation

1. Clone this repository into your ComfyUI custom_nodes directory:

   cd ComfyUI/custom_nodes/
   git clone <your-repo-url> ComfyUI-SimpleCSVParse
   

2. Restart ComfyUI

Usage

CSV File Format

Create a CSV file with two columns (header row is optional and will be auto-detected):

positive_prompt,negative_prompt
a beautiful landscape,"blurry, low quality"
a cute cat,"distorted, ugly"
a futuristic city,"dark, gloomy"

Note: If your prompts contain commas, wrap them in double quotes as shown above.

Or without headers:

a beautiful landscape,"blurry, low quality"
a cute cat,"distorted, ugly"
a futuristic city,"dark, gloomy"

Using the Node

The node automatically detects which input method you're using. You can either select from a dropdown or enter a custom path.

Option 1: From Input Folder (Dropdown)

1. Place your CSV file in the ComfyUI input folder
2. Add the "Simple CSV Parser" node to your workflow
3. Select your CSV file from the csv_from_folder dropdown
4. Leave csv_custom_path empty
5. Set the index to choose which row to read (0 = first row)
6. Toggle "use_negative_prompt" on/off to include the negative prompt column
7. Connect the outputs to your prompt nodes

Option 2: From Custom Path

1. Add the "Simple CSV Parser" node to your workflow
2. Enter the full path to your CSV file in the csv_custom_path field
   • Mac/Linux example: /Users/yourname/Desktop/prompts.csv
   • Windows example: C:\Users\yourname\Desktop\prompts.csv
   • You can use ~ for your home directory: ~/Desktop/prompts.csv
3. The csv_from_folder dropdown will be ignored if custom path is provided
4. Set the index and toggle as above
5. Connect the outputs to your prompt nodes

Outputs

• positive_prompt (STRING): The positive prompt from the selected row
• negative_prompt (STRING): The negative prompt from the selected row (empty if toggle is off)
• total_rows (INT): Total number of rows in the CSV (useful for looping)
• total_rows_string (STRING): Total number of rows as text (for connecting to ShowText nodes)

Example CSV

See example.csv for a sample file format.

Notes

• The node automatically detects and skips header rows if they contain common headers like "positive", "positive_prompt", or "prompt"
• Index is 0-based (0 = first data row after any header)
• If the index exceeds the number of rows, an error message is returned
• Empty cells are handled gracefully
