Hi and welcome to this tutorial on how to export a Firebase collection to a CSV file in Flutter.

Exporting data from a Firebase collection to a CSV file can be a useful way to backup or analyze your data. CSV, or Comma Separated Values, is a simple and widely supported file format that can be opened in a variety of applications, including spreadsheets and databases.

In this tutorial, we will show you how to use the Flutter framework to export a Firebase collection to a CSV file. This process involves retrieving the data from the Firebase collection, extracting the data that you want to include in the CSV file, creating a CSV string, and writing the string to a file.

We will start by installing the necessary dependencies and importing them in your Flutter code. Then, we will retrieve the data from the Firebase collection and extract the relevant data for each document.

Finally, we will demonstrate how to display a message or perform some other action to let the user know that the export was successful.

By the end of this tutorial, you will have learned how to export a Firebase collection to a CSV file in Flutter and will have the knowledge and tools to do so in your own projects.

I've been looking for this everywhere! <3

HI too good.
Thank you very much for your video.
Let me implement it and give you feedback.

[SasoJakljevic]

Awesome, thank you. I've implemented it in my own project faster because of your tutorial.

Dimitar, thank you very much for this informative video. I have one question: How can I pull the details from the document reference in this code?

I am exporting a CSV file of all orders placed by customers, and I want to include the product data (name and price) for each order. The product data is stored as a document reference in the orders table. Please note that the product reference is an array, so one order can have multiple products.

Any help would be greatly appreciated. Thank you in advance.

You mention Supabase in the title of your video but I do not see anything about Supabase. Is there a way to export a CSV using Flutterflow and Supabase?

[musaabdulrahamanomale]

Thank you for this wonderful tutorial, in my case I want to call the send email action and attach the csv file, how do I return the csv file from this custom action?

[RajeevSharma-iifx]

Hi Dimitar, the file is getting downloaded but the data inside the file is quite jumbled. So many fields in the wrong column. Any idea why this is happening? I even modified the code to use the ~ character instead of comma as separator (since no text has ~ in the data so there is no confusion). But the problem is still there.Any suggestions? Thanks.

Hi there, thanks for this, it's perfect. But I'd like to know if have you tried something like this but with subcollections? or did you consider it's better to work only with collections?

[yusufabkuki]

Thank you so much for the video. Everything works great on the web but on iOS nothing happens. Is there any additional step to get it working on iOS. Really helpful video.

[blackbeauty]

hello sir. Beautiful tutorial. Please I am a novice in flutter. Please is it possible to export a document only if the a field in the document is equal to a particular user? eg. export order only if the orders are created by user a.

[andreasfun]

In Flutterflow in your custom action on the right I see that you have no "return value" set and you have no errors, yet your custom action returns. How is this possible??

[aegisong]

Is there any way to format the DateTime to Date or just to time before exporting to CSV? If not the return value is 57:37.2 in Excel, and I have to click on the value to show 4/18/2023 6:57:37 AM. I just need the Date or maybe the Time and not both values together.

[maxichamas]

Hello! good video. Can it be implemented with Supabase? That changes? Thank you!

How can my user import an xls/excel file to create documents in Firebase?

[garvit]

Hey, when I built the app and tested APK on my phone, it isn't working. It works fine in test mode in flutterflow but nothing is happening on my phone.
Do you know why??

[aaronshailrepair]

I followed the steps exactly but I'm getting an error that says "action declaration not found" and it won't save my custom action
