# Changing the look of a Text String

Discover how to changing the look of a text string

In this article we will learn how you can change the look of a text string using the text functions: LOWER, UPPER, TRIM.

  
1\. LOWER

2\. UPPER

3\. TRIM

## **LOWER() and UPPER()**

The LOWER function takes a string of text and makes all the characters lowercase. Conversely, UPPER changes all characters in a string of text to uppercase.

  
Here, example: LOWER(“Is it a Holiday Today?”)  
Result : is it a holiday today?

Alternatively, replacing LOWER with UPPER accomplishes the opposite result: IS IT A HOLIDAY TODAY?

## **TRIM()**

The TRIM function serves a singular purpose: to remove blank space from the beginning and end of a string. Let's see what that looks like in action:

**Result: is it a holiday today ???**

Combined with other functions, TRIM can help you accomplish more.   
For example, if you want a character count for a text field but don't want to count blank spaces at the beginning and/or end, then you can use this formula:

**Result: 22**

If you wanted to remove all of the blank spaces from a string, then another formula would work better in this instance.

**Result: is-it-a-holiday-today?**
