Power Apps Trim | Power Apps Remove First Character from String

I recently received a task in which I needed to remove the first and last characters from a string and all spaces from the string in Power Apps. Fortunately, Microsoft Power Apps provides Trim and TrimEnds Functions to achieve this.

In this Power Apps tutorial, I will explore all the information about the Power Apps Trim function, Power Apps TrimEnds function, and Power Apps remove first character from string.

Also, we will see how to work with Power Apps remove last character from string, Power Apps replace spaces in string, and Power Apps remove special characters from string with examples.

Power Apps Remove First Character from String

Suppose you want to remove the first character from the string. You can follow the code below.

Text = Right(
    " A Power Apps Tutorial",
    Len("A Power Apps Tutorial") - 1
)

Where,

• ” A Power Apps Tutorial” = Power Apps string value

In this example, I have a Text label control that contains the string ” A Power Apps Trim Function.” Now, I would like to remove the first character[“A”] from the string. To do so, follow the code below.

Text = Mid(
    "A Power Apps Trim Function",
    2,
    Len("A Power Apps Trim Function") - 1
)

This is how we can remove the first character from a string in Power Apps.

Power Apps Get First Character from String

To get the first character from the Power Apps string, follow the code below.

Text = Trim(
    Last(
        FirstN(
            Split(
                txt_Address.Text,
                ","
            ),
            1
        )
    ).Value
)

Where,

• txt_Address = Power Apps text input control name

Power Apps Remove Last Character from String

Let’s say I have a string as “IT,Sales,HR,Finance,Marketing,” in a Text label control. Now, I would like to remove the additional last character “,” at the end of the string.

To achieve it, follow the code below.

Text = Left(
    "IT,Sales,HR,Finance,Marketing,",
    Len("IT,Sales,HR,Finance,Marketing,") - 1
)

Power Apps Get Last Character from String

In this example, I will show you how to get the last character from a string in Power Apps. To do so, follow the code below.

Text = Last(
    Split(
        txt_Address.Text,
        " "
    )
).Value

Power Apps Remove Spaces from String

Next, I will show you how to remove spaces from a string in Power Apps. Follow the code below.

Text = Substitute(
    txt_Address.Text,
    " ",
    ""
)

Similarly, in Power Apps, there is a single-column collection named colSentences. To create the string collection, I took a Button control (Click Me) and applied the code below to its OnSelect property.

OnSelect =  ClearCollect(
    colSentences,
    [
        "   Let   him   play   ",
        "    This   book   is   torn",
        "No way any more",
        "   Left,   Right,   Middle  ",
        "Make it hurry   "
    ]
)

Where,

• colSentences = Collection name

Next, insert a Gallery control and set its Items property to the below code:

Items = Trim(colSentences)

Now save and preview the app. When you tap on the button (Click Me), the trim result [Without spaces] will appear in the gallery control, as shown below.

Note:

If you open the collections, then you can see the extra spaces don’t appear by clicking on the collections name. For this type of string length, you can use the Power Apps Len function.

Power Apps Replace Spaces in String

Finally, I will show you how to replace spaces in the Power Apps string with a simple example.

Example:

In Power Apps, I have a variable having the text value “Welcome To PowerApps” that contains some spaces. Now, I want to replace those spaces with a different character, such as an underscore “_.”

To work around this, follow the below steps. Such as:

1. On the Power Apps app, select the App object [From the left navigation] and set its OnStart property, as shown below.

OnStart = Set(varText, "Welcome To PowerApps")

Where,

• varText = Power Apps variable name

2. Next, on the Power Apps, insert a Text label and set its Text property to the code below.

Text = Substitute(
    varText,
    " ",
    "_"
)

This way, you can work with the Power Apps replace spaces in string.
