JSON to text in JavaScript
function textFromJson(json) {
if (json === null || json === undefined) {
return '';
if (!Array.isArray(json) && !Object.getPrototypeOf(json).isPrototypeOf(Object)) {
return '' + json;
const obj = {};
for (const key of Object.keys(json)) {
obj[key] = textFromJson(json[key]);
return Object.values(obj).join(' ');
