# Firestore Content Manager
> This page is about FlutterFlow Studio (the visual builder), not FlutterFlow (the app builder you use by describing your app).
URL: https://docs.flutterflow.io/integrations/database/cloud-firestore/firestore-content-manager
Learn how to use the Firestore Content Manager in your FlutterFlow Studio app to manage Firestore data efficiently.
The Firestore Content Manager provides an easy way to visually create, edit, and add documents
to your [**Firestore database**](https://docs.flutterflow.io/integrations/database/cloud-firestore/getting-started).
:::note
Subcollections are not supported in Content Manager at this time.

:::note[Prerequisites]
Before getting started with this section, ensure you:
1. Become familiar with [**Structuring the Firebase Database**](https://docs.flutterflow.io/integrations/database/cloud-firestore/getting-started#structuring-the-database).
2. Completed all steps in the [**Firebase Setup**](https://docs.flutterflow.io/integrations/firebase/connect-to-firebase).
3. Create a [**Collection**](https://docs.flutterflow.io/integrations/database/cloud-firestore/creating-collections).
4. [**Defined the Fields**](https://docs.flutterflow.io/integrations/database/cloud-firestore/creating-collections#define-schema-creating-fields) for the collection. Only fields defined in
your Firebase schema are
shown in the Firebase Content Manager.

## Adding Document
Before you add a new document to the collection, make sure you have some Fields added. For instance, the 'exam_result' collection with basic fields looks like this:
'exam_result' collection
To add a document:
1. Head to the **Firestore** (left side Navigation Menu) and click **Manage Content**. This will
open up a new browser window.
2. Select the **Collection** to which you want to add a document and then select + **Add Document.** A popup will appear.
3. Enter the information for the record and click **Add Document**.
:::caution
If you get this error "**Could not create an account as firebase@flutterflow.io to your Firebase
project**", just enable the '[**Email Sign-In**](https://docs.flutterflow.io/integrations/authentication/firebase/email-login)' in your
Firebase
project.

### Upload CSV file for bulk addition
You might want to migrate your data from somewhere else to the collection of your current project. Adding an extensive list of records one by one is an incredibly time-consuming process. If you can get or already have data in a CSV (comma-separated values) file, we allow uploading the CSV file, and your data will be loaded into the collection in just a few steps.
:::note
To successfully upload the data:
* Ensure you have header rows in your CSV file. The header should contain the exact name of the fields you have in your collection.
* If you are uploading lat-long data, make sure you format it like (lat, lng) or [lat,lng].
* Dates must be in a format like YYYY-MM-DD HH:MM:SS, where hours should be in 24hrs format (e.g., 2022-11-07 13:05:32).

To better understand, here is the sample places collection and CSV file:
**_places.csv_**
```
name,location,last_updated
Central,"(40.76835069123224, -73.97203144014624)",2022-11-07 13:05:32
Museum,"(40.8217031079394, -73.9256367137398)",2022-11-09 16:12:02
Zoo,"(40.85452267684994, -73.8774290321384)",2022-11-04 03:05:54
```
Here's how you upload the CSV file:
1. Select the **Collection** and click the **Upload CSV** button (see top right side). A popup
will open.
2. Click **Select File** and upload your CSV file.
3. Now, you can choose the **Separator Type** and enter the **Number of Rows to Upload**. If you leave this empty, all records will be imported.
4. Click **Upload CSV** button.
5. Once the file is uploaded, you'll see the preview of data with field name and its data type.
6. Click **Validate & Import**. If everything looks good, this will import the data and you can **Finish and Close**. If there is any issue with data type mismatch or formatting issue, you'll see a message like this:
Formatting issue
If your CSV file contains additional fields, you'll go through a quick *field import process* that will add the new fields with their data in your collection.
