It works for me.

I used Cloud Functions to export all data in Firestore to JSON format. The function that I was used:

exports.exportFirestore2Json = functions.https.onRequest((request, response) => {
    db.collection("data").get().then(function(querySnapshot) {
        const orders = [];
        var order = null

         querySnapshot.forEach(doc => {
             order = doc.data();
             orders.push(order);
         });

         response.send(JSON.stringify(orders))

         return true
    })
    .catch(function(error) {
        console.error("Error adding document: ", error);
        return false
    });
})

Then, go to https://your-project-id.cloudfunctions.net/exportFirestore2Json you will see something like this

Google made it harder than it needed to be, so the community found a workaround. If you have npm installed, you can do this:

Export

npx -p node-firestore-import-export firestore-export -a credentials.json -b backup.json

Import

npx -p node-firestore-import-export firestore-import -a credentials.json -b backup.json
