ComfyUI_StringOps

Wrap any string in a prefix and suffix — the two-field wrapper

Prefix and suffix every line of a block — formatting lists in bulk

Run a whole dictionary of text replacements in one pass

Does this text contain that string? Returns 1 or 0, ready to route on

Classify a number as small, medium, or large — then route on the label

Pick one of two strings based on a substring check

Count how many times a string appears — as both a number and text

Crop an image and its mask in lockstep, so inpainting never misaligns

VAE-decode to a preview — and still keep the image on the wire

Pull a range or a set of lines and rejoin them into one string

Grab everything before or after a marker — first or last occurrence, your call

Slice a block of text into five named chunks in one node

Two mini-languages for pulling structured data out of text

Pull exact lines out of a block by position — with a bonus combined output

Pull the text trapped between two labels — the tag-between extractor

Cut a string by character range instead of guessing a regex

Copy or move files from inside a workflow — with a status string instead of a crash

Clean out your ComfyUI output folder from inside a workflow — carefully

List every file in a folder by extension — full paths, count, and a list, all at once

Rename in your graph without touching the disk — it builds the new path, you decide what to do with it

Keep or drop lines by keyword — grep, but inside your workflow graph

Keep only the lines that are the right length — a dumb filter that's quietly great

Search an Excel sheet from inside a workflow and get the cell's row and column back

Scan lines for a marker and return everything after it on that line

Stop fighting ComfyUI over int vs float — round, ceil, floor, or snap to 32

Build a padded number list for batch queues without math nodes

One node that turns a plain scene description into a cinematic video prompt

Load an image from a path, a URL, or a base64 blob — one input, same IMAGE out

A live clock in your graph — and the pack's built-in 'random' seed trick

The text-to-float bridge for config lines and batch output

Find the line that contains your key and hand back the int value on it

A random number node that re-rolls every single run — that's the point

One node to resize any image to a sane, model-friendly size — and hand you back width and height

Stack two images with alignment, scale, and opacity — watermark and composition in one node

One node that loads an image, resizes it, and hands you a mask

Four inputs, four outputs, zero processing — the pass-through node

Turning a '2|3' string into two usable integers

One node to clean every prompt before it hits the text encoder

The wildcard-style random prompt picker, without the wildcard plugin

Reading cells out of an .xlsx and into your workflow

How many filled cells are in that row? This node counts and diffs them

It's called 'read page' but it actually phones home to the author's server

Strip everything between two characters — parens, brackets, tags, gone

Replace the same string N times — each time with a different value

Replace only the 3rd 'X' — or every one, if you set it to 0

Save images to any folder you want — and get the image back out

A gender + orientation picker that outputs '1+1' — and probably isn't for you

Randomize your lines, fresh every single run

A random seed you can actually wire in — string and int, fresh every run

The boring find-and-replace node you'll reach for constantly

A text input node with zero processing. Yes, that's the whole thing.

Grab the nth piece of a delimited string — forward or backward

Split a string in two at the first delimiter you give it

Snap your resolution to a small/medium/large preset in one step

Rules with [1] [2] placeholders, up to five outputs

Join up to four strings in any order you like — not just 1+2+3+4

Turn 'is this prompt good enough' into a clean 0 or 1

Turn text into an image — with working Chinese font support out of the box

Turn a multiline box into a real STRING list — clean and empty-line-free

Write your workflow's output back into an .xlsx, row by row
