Tests:

Object.fromEntries
Object.fromEntries(Object.entries(data).map(([key, value]) => [key, value.toString()]));
Reduce (reuse object)
Object.entries(data).map(([key, value]) => [key, value.toString()]).reduce((acc, [k, v]) => { acc[k] = v; return acc; }, {});
Reduce (map in reducer)
Object.entries(data).reduce((acc, [k, v]) => { acc[k] = v.toString(); return acc }, {});
