Int → String

You can't put a number into a text field, and ComfyUI is firm about it - INT wires refuse to connect to STRING ports. But text is where the useful stuff happens: filenames, saved prompts, metadata, labels. SL_IntToString is the conversion that turns 5 into "5" so you can drop an integer parameter into any string context.

The mechanism is one line of Python: str(value). No formatting, no padding, no localization - the integer's plain decimal representation, exactly as you'd type it. 5 → "5". -3 → "-3". That's the whole behavior, and it's refreshingly predictable compared to its float sibling, which drags a decimal point and possible floating-point noise along with it (SL_FloatToString gives you "5.0", this gives you "5").

Inputs and outputs:

• value (INT) - the integer, default 0
• Output: STRING - its text form

Installing it

Part of ComfyUI-SimpleLogics. Manager → search "SimpleLogics" → install → restart. Manual:

cd ComfyUI/custom_nodes
git clone https://github.com/danipisca07/ComfyUI-SimpleLogics

Restart, Add Node → search "Int → String" (menu group SimpleLogics/Convert). Zero dependencies, no models.

Where it shows up

• Dynamic filenames: bake a seed, step count, or batch index into a save path (seed_4521.png).
• Prompt injection: build prompts or text templates with a number literal inside, so a parameter shows up in the text the sampler sees.
• Metadata and labels: stringify a value to store it alongside your workflow or show it on a display node.
• Chaining into string operations: feed text-processing nodes that need everything as STRING.

Gotchas

• No leading zeros, no formatting. If you wanted "007", this node won't produce it - you'd pad the string elsewhere.
• It's the whole number. No decimal point, no rounding surprises - this is actually the cleaner of the two number-to-string conversions in the pack. Use it whenever your value is genuinely an integer.
• Concatenate downstream, not here. The node outputs one number as a string; combining it with other text is done by the string-concatenation or text nodes that follow, not by this node.

It's a one-trick utility with no traps. If your workflow saves files or builds text from numbers, this is the node that makes it possible.
