How to import CSV or JSON to firebase cloud firestore

Question

Is there a way to import CSV or JSON to firebase cloud firestore like in firebase realtime database?

Answer 1

This is a small modification that copies the 'id' of the document, if exists, to its path. Otherwise it will use the "for"'s index.

  ...
  ...
  } else {
    // Collection's length of is always odd.
    for (const key in data) {
      // Resolve each collection.
      if (data[key]['id']!==undefined)
        await resolve(data[key], [...path,data[key]['id']])
      else 
        await resolve(data[key], [...path, key]);
    }
  }
}

resolve(data);
