I have hundreds of entries in my firebase database and I’d like to try moving to SQL in case my Firebase free plan ever goes out of limit. Is there any way I can export the data in JSON format without buying the Blaze plan? (as my card doesn’t work when I try to do payment)

To backup my collection manually I did this:
1. In the same project, created a file called backup.js that is called when I press a backup button.
2. In the backup.js endpoint, I fetch the collection and store every entry in the database, then I return this array of documents I just saved.
3. I console.log the returned data and in Browser's console, I right click the array output and click 'Copy Object' and save it in a text file.
backup.js (Next.js API Endpoint):
```
import { collection, doc, getDoc, getDocs } from "firebase/firestore";
import { StatusCodes } from "http-status-codes";
import { db } from "../../utils/firebase";

export default async function handler(req, res) {
  const collectionName = "myCollection"

  try {
    // check firebase if slug exists
    const documentSnapshot = await getDocs(collection(db, collectionName));

    let backup = [];
    documentSnapshot.forEach((doc) => {
      backup.push(doc.data());
    });
    console.log(backup);
    return res.status(StatusCodes.OK).send(backup);
  } catch (err) {
    console.log("Database Error", err);
  }
}
```
