Supabase-Googlesheet

In this repo, you will see how to pull datas from your supabase project using Supabase API to a Google Sheet. No matter how many fields and rows you want to pull, this should always work. If not, feel free to contact me so that we can look at your issue.

The code

You can get it here.

If you find any issue related to the code, please contact me so that I can help you.

Prerequisites

This project assumes that you are already familiar to supabase and Google appscript.

You will need :

• the URL of your supabase project
• its API KEY (service role or anon one, depending your RLS)

And of course : your Google account.

How often can I refresh datas ?

• Every minute
• Every hour
• Every day
• At a specific date
• On a special event (event-driven triggers)

More informations about Google script triggers here.

CAUTION : be careful of your daily quotas on your Google account. For a free account, you can have 90 minutes of runtime per day (July 2022). Check out the details of Google triggers quotas here.

Motivation

Google Scripts can't handle postsgresql connections yet, so here is a workaround to pull datas everyday at the same hour. We don't really want a realtime update. Just a snapshot is enough.

Once the datas are available on your Google Sheet, you can explore many possibilities, like using Google Data Studio that pulls datas from Google Sheets every 15 minutes.

Limits and recommandation

• Your daily quota from your Google account as stated before
• Your supabase max rows limit, which can be changed here :

I highly recommand you to :

• set this parameter according to the average amount of datas you are going to pull (here for me is ~3.5k rows so I have 500 as an offset)
• NOT set this parameter too high (as low as possible actually) or/and to create a strong RLS to make sure that :
  • your supabase API is not over loading (I already tried with 10k rows and it's definitely NOT a good idea)
  • your users don't over pull your datas

Roadmap

• MVP limited by supabase max row limits
• Paginations (to fetch all datas)

Have fun with your datas !
