Text Split By Delimiter

You've got one big text field with a bunch of prompts in it, separated by commas or newlines, and you want them as a list so a batch can run through each one. This node does exactly that split - plus a few slicing controls so you can grab a subset instead of the whole thing. It's the glue between "a text box full of ideas" and "render all of these."

How it works

Give it a text blob and a delimiter, and it cuts the text at every delimiter into separate pieces, handing back a list of strings. So "a cat, a dog, a bird" split on , becomes three list items. The extra parameters let you slice that list - start partway in, skip some, cap the total - without editing the source text.

The inputs that matter

• text - the blob to split. Multiline, so newline-separated lists work fine.
• delimiter - what to cut on. Default is , (comma). Set it to a newline, a semicolon, or any character your text uses to separate items. This is the one you'll always set to match your data.
• max_count - the biggest number of items to return (default 10). Your batch-size cap. If your text has 50 prompts and you only want to render 10, this is where you say so.
• start_index - skip the first N items and start there. Handy for resuming or grabbing a later chunk.
• skip_every - drop items at a regular interval, thinning the list. Leave at 0 to keep everything.

Output is a STRING list - the pieces. Feed it into a batch prompt setup, a loop, or Mixlab's app batch-prompt feature.

Installing it

Get the pack via ComfyUI Manager (search mixlab, install comfyui-mixlab-nodes, restart), or clone it:

cd ComfyUI/custom_nodes
git clone https://github.com/shadowcz007/comfyui-mixlab-nodes

then install requirements and restart. No downloads - it's plain string handling.

Common snags

• You get one giant item instead of a list. Your delimiter doesn't match what's actually in the text. If your prompts are on separate lines, the delimiter needs to be a newline, not a comma.
• Extra blank or whitespace-padded items. Splitting on , leaves the spaces after each comma attached to the next item ("a cat" vs " a dog"). If a downstream node is fussy, trim the results, or split on , including the space.
• Fewer items than you put in. Check max_count, start_index, and skip_every - any of the three will quietly shrink the list. If you want everything, set max_count high, start_index 0, skip_every 0.
• Pairs beautifully with RandomPrompt or an LLM node: generate or collect a pile of prompts as one string, split them here, batch-render them all.
