“Can JavaScript button copy & format text in lower case?”

I’m using a button to copy all text from an "input text area", but I need the text to be in uppercase and the script to format everything in lowercase.

How to make it uppercase?

function myFunction() {
        // Get the text field
        var copyText = document.getElementById("myInput");
        // Select the text field
        copyText.select();
        copyText.setSelectionRange(0, 99999); // For mobile devices
        // Copy the text inside the text field
        navigator.clipboard.writeText(copyText.value);
}

    You can use the .toLowerCase() And .toUpperCase()functions to modify a string to be either fully lower or upper case

    let text = "this text is fully lower case"

console.log(text.toUpperCase()) // logs: "THIS TEXT IS FULLY LOWER CASE"

    You can try this, see the edit in last line:

    function myFunction() {
        // Get the text field
        var copyText = document.getElementById("myInput");
        // Select the text field
        copyText.select();
        copyText.setSelectionRange(0, 99999); // For mobile devices
        // Copy the text inside the text field
        navigator.clipboard.writeText(copyText.value.toLocaleLowerCase()); // Add this
}
