This is a sample script for creating a table to Google Document by retrieving values from Google Spreadsheet for Golang.
Before you use this script, please install go library of go-gdoctableapp.
$ go get -v -u github.com/tanaikech/go-gdoctableapp
Sample script:
This sample script uses Service Account.
In this sample script, the values are retrieved from Sheet1!A1:C5 of Spreadsheet, and new table is created to the Document using the values.
