Question details

The user needs a text input field in Power Apps to automatically display characters in uppercase as they are being typed, rather than converting them only after the input loses focus.

Product: Power Apps
Device & OS: not provided
Scenario: Collecting specific formatted data, such as vehicle registration marks, where real-time capitalization is required for an optimal user experience.
Observed behavior: By default, text inputs only convert to uppercase upon the OnChange event, which occurs after the user has finished typing and clicks away from the field.

Before you start

Ensure you have editing permissions for the Power Apps canvas app and are familiar with modifying control properties. You will also need access to a web browser to review advanced implementation formulas on the official community forums.

Consult the Power Apps Community for Real-Time Transformation Formulas

Because Power Apps requires specific control property configurations or formula workarounds for real-time text formatting, utilizing the official Microsoft Power Platform Community is the most effective approach.

While the standard OnChange property executes after a user finishes typing, achieving keystroke-level uppercase formatting often requires specialized techniques, such as using context variables or adjusting specific input controls.

Frequently Asked Questions

Can I use the OnChange property for uppercase formatting in Power Apps?

Yes, you can use the Upper() function within the OnChange property, but this will only convert the text to uppercase after the user clicks away or presses Enter, not while they are actively typing.

Is there a native property to force uppercase in Power Apps text inputs?

As of recent versions, standard Power Apps text inputs do not have a simple toggle switch for 'force uppercase' during typing. This is why community workarounds using variables or modern controls are frequently required.

How do I capitalize text in standard spreadsheet software like WPS Spreadsheet?

In WPS Spreadsheet, you can use the UPPER() function in an adjacent cell to instantly convert text to uppercase, or utilize data validation to ensure specific formatting rules are followed when users enter data.
