How to use the Text Load Line From File node from WAS Node Suite to dynamically load prompts line by line from external text files into your existing ComfyUI workflow.

Requirements

• ComfyUI Manager: Recommended to manage plugins.
• ComfyUI Custom Scripts : Provides the Show Text 🐍 node.
• WAS Node Suite : Provides the Logic Boolean, Number Counter, Text Load Line From File nodes used in this workflow.
• Your text file with pre-made prompts, one per line.

Workflow preview

Whenever this workflow is run, a new prompt will be read from the specified text file using a combination of the Text Load Line From File and Number Counter nodes.

With fixed boolean node.

To execute all prompts from your file, set the queue batch count to the amount of lines in your file, then click the Queue button once.

Load Prompt from File group explained

Load Prompt from File group. The optional green nodes are for preview only and can be skipped.

1. Your prompts text file should be placed in your ComfyUI/input folder
2. Logic Boolean node: Used to restart reading lines from text file.
   1. Set boolean_number to 1 to restart from the first line of the prompt text file.
   2. Set boolean_number to 0 to continue from the next line.
3. Number Counter node: Used to increment the index from the Text Load Line From File node, so it reads the next line each time the prompt is queued.
   1. Set start to the first line you want to read from the prompt file.
   2. Set stop to the last line you want to read from the prompt file.
   3. Set step to 1.00 to increase the counter by 1 each time the propmt is run.
4. Text Load Line From File: used to read a line from the prompts text file.
   1. Convert the node’s index value to input.
   2. Set the file_path to the full prompt file path and name.
   3. Set mode to index.
5. Primary Show Text 🐍 node: Used to preview the last loaded prompt. Every time the prompt is queued, this will show the next loaded line from your prompts text file.
6. Secondary Show Text 🐍 node: Used to display the next line number that will be loaded from the prompt text file on the next prompt queue.
7. Clip Text Encode: This node had its text converted to input in order to connect it to the line_text output of the Text Load Line From File node.

Once you have connected the Text Load Line From File node line_text output into the Clip Text Encode node’s text input, the rest of the workflow will continue as usual.

The sample Save Image node uses the filename_prefix %date:yyyy-MM-dd%/%date:hhmmss%_%KSampler.seed% to save the images on a folder with current date.
