These nodes are designed to make workflow automation easier when working with LLMs, APIs, JSON data, custom nodes, loop systems, and dynamic workflow logic.

Features

Convert any input to INT
Convert any input to FLOAT
Convert any input to STRING
Convert any input to BOOLEAN
Accepts a single ANY input
Returns a strongly typed ComfyUI output
Safe fallback values on conversion errors
Lightweight and easy to use

Included Nodes

Convert To Integer

Converts any supported input into an INT.

Examples:

| Input | Output | | ----- | ------ | | "6" | 6 | | 6.9 | 6 | | True | 1 | | False | 0 | | None | 0 |

Fallback value:

Convert To Float

Converts any supported input into a FLOAT.

Examples:

| Input | Output | | ----- | ------ | | "6.5" | 6.5 | | 6 | 6.0 | | True | 1.0 | | False | 0.0 |

Fallback value:

0.0

Convert To String

Converts any input into a STRING.

Examples:

| Input | Output | | ----- | ------ | | 123 | "123" | | True | "True" | | 6.5 | "6.5" |

Convert To Boolean

Converts any supported input into a BOOLEAN.

Examples:

| Input | Output | | ----- | ------ | | "true" | True | | "false" | False | | 1 | True | | 0 | False |

Fallback value:

False

Why Use These Nodes?

These nodes are particularly useful when working with:

Ollama
OpenAI
Gemini
JSON outputs
Loop systems
Conditional logic
API integrations
Dynamic ComfyUI workflows

Many LLM and API nodes return values as strings, while other ComfyUI nodes require specific data types such as INT, FLOAT, or BOOLEAN.

These conversion nodes provide a simple bridge between those systems.

Example:

Condition Switch

Installation

Copy the zfrsgtcu-ComfyUI folder into your ComfyUI custom_nodes directory.

Example:

ComfyUI/custom_nodes/zfrsgtcu-ComfyUI

Restart ComfyUI.
The nodes will appear under:
