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.

  • 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.
