# Manipulate Text
> Modify a text value using various operations
The **Manipulate Text** action allows you to modify text values by applying various different manipulation operations on the text.
***
### Input Text
The **input text** is the base text value that the manipulative operation will be performed upon. This may be static text or a variable.
### Operation
The **operation** dictates the way your text vaue will be manipulated. Below are listed the available operations that can be applied to a text value using the Manipulate Text action:
| **Operation** | **Description** | **Example Output** |
| ------------------ | ------------------------------------------------------------------------------------------ | :----------------- |
| To Uppercase | Converts text to all capital letters | HELLO THERE |
| To Lowercase | Converts text to all lowercase letters | hello there |
| Trim Spaces | Removed all spaces from the text, including leading/trailing spaces | HelloThere |
| Replace Text | Replaces all instances of a specific string found in the text with another specific string | Hello Bob |
| Split by Delimiter | Splits the text into fragments, using a specific character as a boundary marker | \[Hello,There] |
| Concatenate | Appends additional text to the existing text value | HelloThere |
### Reference Variable
This variable allows you to refer to the result of the text manipulation in future action blocks down your endpoint's flow. This variable must be assigned a custom name.
Make your reference variable names as descriptive and unique as possible to prevent your endpoint flow from becoming cluttered. If a future variable is assigned the same name, the value of your reference variable will be overriden.
