At that point, you are just being unreasonable to keep marching on your crusade.
Frankly, this ain’t kind of crusade I want to join.
You should really rethink how you design your query. If I remember correctly you already have normalized tables and those JSON types are just coming from the view. This means you are creating problems yourself. You currently don’t have a heterogeneous schema, so why bother using JSON?
Anyway, this hasn’t been thoroughly tested but works for your case.
function unstringify(val) {
try {
const parsedValue = JSON.parse(val)
switch(true) {
case Array.isArray(parsedValue):
return parsedValue.map(unstringify)
case typeof parsedValue === 'object':
return Object.entries(parsedValue).reduce((o, [key, val]) => {
o[key] = unstringify(val)
return o
}, {})
default:
return parsedValue
}
} catch(e) {
return val;
}
}
function parse(obj) {
return Object.entries(obj).reduce((o, [key, val]) => {
o[key] = unstringify(val)
return o
}, {})
}
