Trim Text

Uncontrolled node

Overview

The Trim Text node removes whitespace characters (spaces, tabs, newlines, etc.) from the beginning and/or end of a text string. This is useful for cleaning up user input, removing accidental leading/trailing spaces from data, or standardizing text formatting before further processing.

The node supports three trimming modes:

• Trim Both: Removes whitespace from both the start and end of the text (default)
• Trim Start: Removes whitespace only from the beginning of the text
• Trim End: Removes whitespace only from the end of the text

Inputs

Input	Type	Description	Default
Text	Text	The input text string to be trimmed.	-

Outputs

Properties

Trim Sides	Enum	Determines which side(s) of the text to trim whitespace from. Options: trimBoth, trimStart, trimEnd.	trimBoth

Runtime Behavior and Defaults

The Trim Text node is an uncontrolled data node, meaning it executes immediately when its input changes and does not require an event trigger to run.

• Default Behavior: If no trimSides property is specified, the node defaults to trimBoth, removing whitespace from both ends of the input text.
• Non-string Input: If the input is not a string, the node returns an empty string.
• Whitespace Definition: The node uses JavaScript's standard trim(), trimStart(), and trimEnd() methods, which remove all whitespace characters including spaces, tabs, newlines, and other Unicode whitespace characters.

Example

Basic Usage

Connect a text source (such as a Plain Text node or form input) to the Text input. The node will automatically output the cleaned text.

Input: " Hello World "
Property: trimBoth (default)
Output: "Hello World"

Input: " Hello World "
Property: trimStart
Output: "Hello World "

Input: " Hello World "
Property: trimEnd
Output: " Hello World"

Cleaning Form Input

Use Trim Text to clean up user input before validation or database insertion:

1. Connect a Form Data node (capturing a text field) to the Text input
2. Set Trim Sides to trimBoth to ensure no accidental spaces are stored
3. Connect the Output to a Set Variable or database insertion node

This ensures that entries like " user@example.com " are stored as "user@example.com".
