Right click in side bar -> select 'New file' -> give it a name ending with the `.json` extension. But somehow I believe that's not what you are really asking. – Mathyn Aug 14 '20 at 12:03

`const fs = require('fs'); fs.writeFileSync('my.json', JSON.stringify(objJson));` – Nikita Madeev Aug 14 '20 at 12:03

You can use JSON.stringify(objJson) to turn it into a string, then save it to a file. I can't tell what you mean by Visual Studio Code, but if you are using NodeJS (like a VS Code extension) you can use the File System Module to save it.
Example:
const fs = require('fs');
fs.writeFileSync(
'data.json',
JSON.stringify(objJson)
);

There is not really a way to do that in JavaScript, but you could save to `localStorage`? – The Otterlord Aug 14 '20 at 12:13

Local storage will save until we close the tab. How to save permanently into harddisk? – Akash Starvin Dsouza Aug 14 '20 at 12:39

Only lost in private browsing. An alternative, especially for larger data is IndexedDB: https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API – The Otterlord Aug 14 '20 at 12:44
