# Trim String

The **Trim String** node is used to remove any leading and trailing whitespace characters from a string. Whitespace characters include spaces, tabs, and newlines that appear before the first non-whitespace character or after the last non-whitespace character in a string.

### Properties Panel

#### General

| **Field**     | **Description**                                                                      | **Required** |
| ------------- | ------------------------------------------------------------------------------------ | ------------ |
| Node name     | [Node Name](https://docs.cosmocloud.io/concepts-and-in-depth/flow-builder/node-name) | true         |
| Variable Name | Variable name containing string which you want to trim                               | true         |

### Example

Let's say you want to remove all the leading and trailing whitespaces in `@wscos@` stored in `$.variables.password`.

1. Set `Variable Name` to `$.variables.password`.

It will convert the string in place and store in the same variable. If variable `$.variables.password` doesn't exist, it'll raise an error.

### Returns

This node does not return any value, but stores the trimmed string in the same variable provided in `<Variable Name>` in the flow context.
