How to Call Google Apps Script Function from Web App

In this post, I demonstrate how to call Google Apps Script Functions from Web App. I also show how to pass parameters in and out of functions.

How to Video:

Video Notes:

  • Legacy Apps Script Editor Used in Video
  • Apps Script (Script Editor) is now located under tab ‘Extensions’ instead of ‘Tools’ on Google Sheets
  • For Further Details on Deploying a Web App Click Here

Code in Video:

function doGet(e) {
  return HtmlService.createHtmlOutputFromFile('WebApp');
}

function getOneCellData() { 
  var ss= SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName("Sheet1"); 
  var data = sheet.getRange('A1').getValue(); 
  return data;  
}

function getMultiCellData() { 
  var ss= SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getSheetByName("Sheet1"); 
  var data = sheet.getRange('A1:C1').getValues(); 
  return data;  
}

function getInOutData(inData) { 
  var outData = "IN DATA: " + inData; 
  return outData;  
}

        document.getElementById("multiData").innerHTML = stringArray;
