Rewriting webhook for checked and unchecked items in form

I need my json file to read “True” or “False” depending on if my form field is checked or unchecked. I split my four questions into separate fields and named them accordingly. I cannot figure out why my JSON files, from my webhook, are returning a “Checked” or “Unchecked”. My code is below:

export function multiStepForm1_wixFormSubmitted ( ) {
$w ( “#multiStepForm1” ). hide ();
$w ( “#box3” ). show ();
if ( $w ( “#checkbox2” ). checked ) {
$w ( “#checkbox2” ). value = “True” ;
}
else {
$w ( “#checkbox2” ). value = “False” ;
}
if ( $w ( “#checkbox3” ). checked ) {
$w ( “#checkbox3” ). value = “True” ;
}
else {
$w ( “#checkbox3” ). value = “False” ;
}
if ( $w ( “#checkbox4” ). checked ) {
$w ( “#checkbox4” ). value = “True” ;
}
else {
$w ( “#checkbox3” ). value = “False” ;
}
}

Where is the code that is creating the json?
