Upper, Lower and Proper functions in Powerapps Form

Suppose, you have a Powerapps Edit Form and that has connected with a Data source (Either Excel or SharePoint List data source). This form has some field inputs where the user can enter some inputs over there and save the form.

But, you want to convert the user input to be Upper case or lower case while saving the form. Then, in that case, you can convert that particular input field to the Upper case or Lower case. Let us take an example for better understanding.

I have a Powerapps Registration form and it has some fields like the below screenshot. Here, I want to make some fields (First Name and Last Name) to the Upper case, So that a user will enter those inputs with the Upper case and submit the Form.

To make those fields (First Name and Last Name) to Upper case, we need to do these below things as:

• Select the Data card (suppose, First Name) that you want to convert the Upper case.
• Unlock the Data card (Select the Data card -> Go to Advanced tab -> Unlock it).
• Next, go to Update property and set this below formula as:

Update = Upper(DataCardValue1.Text)

Where,

DataCardValue1 = First Name field control name that you want to convert it in the Upper case.

In the same way, you will do these above steps for all fields that you want to convert Upper, Lower, or Proper case.

• Now, Save and Preview (F5) the app. Enter the field details as I have entered below. Then, click on the Submit button.

Once you will submit the form, go to your specific Data source (SharePoint List) and you can see the input fields have been converted into the Upper case as shown below.
