Hi there,
We can use Google Script to push the data from Google spreadsheets to Google BigQuery. Google Script can connect to the BigQuery API and of course, it can read the data from Google spreadsheets. In addition, we can make use of Google Script triggers, like perform an update when the spreadsheet is edited, or on a regular interval, like every 5 minutes.
I will be happy to address any of your questions!
Sincerely,
Mohamed
