see how they can transform and enhance user entered text.

00:00:13

Imagine you are creating a Power Apps application with

00:00:17

on one side,

00:00:18

a text input named user text where the user can freely enter text

00:00:22

and on the other side a label meant to display the result of our manipulations.

00:00:27

To start,

00:00:28

the upper function is a simple tool that converts all entered text to uppercase.

00:00:33

By using the formula upper,

00:00:34

each letter of the text will be transformed into uppercase.

00:00:38

This function is ideal for standardizing text display,

00:00:41

especially when the case does not matter.

00:00:44

Conversely,

00:00:45

if you want to convert everything to lowercase,

00:00:48

the lower function is your ally.

00:00:51

To give a professional touch to your text,

00:00:53

you might want to capitalize the first letter of each word.

00:00:56

The proper function is perfect for this.

00:00:59

By using this function,

00:01:01

the first letter of each word will be capitalized,

00:01:04

while the rest of the text remains in lower case.

00:01:07

This is ideal for formatting proper names,

00:01:09

titles,

00:01:10

or any other input that requires a neat presentation.

00:01:15

Extra spaces at the beginning or end of the text can sometimes cause issues.

00:01:19

The trim function helps eliminate them.

00:01:21

By using this function,

00:01:23

all spaces at the beginning and end of the text are removed.

00:01:27

For example,

00:01:27

if the user enters Hello world with spaces before and after,

00:01:31

the result will be returned without the extraneous spaces.

00:01:35

This ensures that the text is formatted

00:01:37

correctly without errors due to accidental spaces.

00:01:41

If you need to know the length of the entered text,

00:01:43

the len function is exactly what you need.

00:01:46

You will get the total number of characters in the text,

00:01:49

including spaces and punctuation.

00:01:51

This is useful for imposing length limits or analyzing user input.

00:01:58

Sometimes you need to replace certain words or phrases in your text.

00:02:01

The substitute function offers you this flexibility.

00:02:04

By applying the following function,

00:02:06

every occurrence of the word power will be replaced with Microsoft Power.

00:02:11

This is an effective way to dynamically correct or adapt user entered content.

00:02:16

But why stop there?

00:02:18

By combining several functions,

00:02:20

you can achieve even more powerful manipulations.

00:02:23

Let's take this complex formula.

00:02:25

What exactly does it do?

00:02:27

First,

00:02:28

substitute removes all spaces from the text by

00:02:31

replacing each space with an empty string.

00:02:34

Then upper

00:02:35

converts the obtained result to uppercase.

00:02:38

Next,

00:02:39

Len calculates the number of characters in the text without the spaces.

00:02:44

Finally,

00:02:45

by assembling everything with Ampersson,

00:02:47

we create a complete sentence that displays the

00:02:49

modified text and the number of characters.

00:02:52

For instance,

00:02:53

if the user inputs Hello world,

00:02:55

the resulting output will be as follows.

00:02:58

This combination displays the text without spaces,

00:03:01

all in uppercase,

00:03:03

and indicates the total number of characters,

00:03:05

thus providing an in-depth analysis in a single formula.

00:03:09

By mastering these functions,

00:03:11

you can transform and adapt user text in multiple ways,

00:03:14

thus enriching the experience within your Power App's application.

00:03:18

Feel free to experiment with new combinations to

00:03:20

uncover the full potential of Power FX.
