Use npm install https://github.com/mrdizzy/dizzy_google_sheets_api.git --save

Require the module and set the spreadsheetId of the spreadsheet you want to use. The spreadsheetID can be found by looking at the URL of the sheet you are working on when using Google Sheets. Eg:

https://docs.google.com/spreadsheets/d/1yLZ5W59IBxDG-8FsqPSgvkv22WySc8h--C-VkA73j9I/edit`

The spreadsheetID comes after spreadsheets/d/SPREADSHEETID

const Sheets = require('dizzy_google_sheets_api')
const spreadsheetId = "1H2-Bo6LhYNEs4zUVmLkbH3F0t1mDoCpZMBA1DBap7A8";

The credentials object must have the following key-value pairs:

{
  client_email: "[email protected]",
  private_key:  "----BEGIN KEY---kjsdkjhskfhsjkdf---END KEY---"
}

These are obtained by creating a Google Cloud service account and creating and downloading a key for that account.

The spreadsheet should also be shared with the client_email: go to share in the Google sheets app and add the client_email generated in the key for the service account. var sheets_api = new Sheets(spreadsheetId, 0, credentials); sheets_api.getRowsIfColumnMatches(["GM10"], "B", function(response) { console.log(response); })
