ComfyUI Node: Concat Text

Concat Text:

The ConcatTextOfUtils node is designed to concatenate two strings together, providing a simple yet powerful way to merge text inputs. This node is particularly useful when you need to combine different pieces of text into a single string, which can be beneficial in various text processing and generation tasks. By allowing you to specify a separator, it offers flexibility in how the strings are joined, making it adaptable to different use cases. Whether you are preparing prompts for AI models or simply need to merge text data, this node streamlines the process, ensuring that the resulting string is formatted according to your needs.

Concat Text Input Parameters:

text1

This parameter represents the first string to be concatenated. It is a required input and supports multiline text, allowing you to input longer strings or multiple lines of text. The default behavior is set to "input," meaning you will need to provide the text manually.

text2

This parameter represents the second string to be concatenated. Similar to text1, it is a required input and supports multiline text. The default behavior is also set to "input," requiring manual input of the text.

separator

This parameter specifies the string that will be used to separate text1 and text2 in the concatenated result. It is a required input but does not support multiline text. The default value is a comma (,), but you can customize it to any string that suits your needs, such as a space, hyphen, or any other character.

Concat Text Output Parameters:

STRING

The output of this node is a single concatenated string. This string is the result of merging text1 and text2 with the specified separator in between. The output is useful for various applications, such as generating prompts, creating combined text data, or any other scenario where merged text is required.

Concat Text Usage Tips:

• To ensure a clean and readable output, choose an appropriate separator that matches the context of your text. For example, use a space (" ") if you are combining words or sentences.
• If you are working with multiline text, make sure to review the combined result to ensure it meets your formatting expectations.
• Utilize this node to prepare text prompts for AI models, ensuring that the input text is formatted correctly and consistently.

Concat Text Common Errors and Solutions:

TypeError: can only concatenate str (not "NoneType") to str

• Explanation: This error occurs when one of the input parameters (text1, text2, or separator) is not provided or is None.
• Solution: Ensure that all required input parameters are provided and are valid strings. Double-check your inputs to confirm that none of them are None.

ValueError: Invalid separator

• Explanation: This error may occur if the separator parameter is set to an invalid value that cannot be used in string concatenation.
• Solution: Verify that the separator is a valid string. Avoid using special characters that may cause issues in the concatenation process.
