Hello @Easy_Buy,
There are a few methods you can use to add multiple rows at the same time in Google Sheets.
You’ll need to construct your own values object and use a Google Sheets Make an API Call module to add them using the batchUpdate endpoint. More details can be found in this post I made about a month ago which goes over how to do it manually or use a third-party custom app (for some fee).
Please check it out and let us know if you have any questions!
