How to Create a Custom Google Sheets Sidebar

Some Google Sheets features seem a bit complicated to work with initially but it can be very easy once you get an idea of the basics.

To create a custom sidebar, you must write and run some Apps Script code. Since this step involves running custom third-party code, the user must grant permission to run the sidebar script. Sidebars can only be displayed when users perform an action, such as clicking on a custom button or selecting a menu item from a custom menu.

In this tutorial, we’ll make a custom sidebar form, that allows you to enter Lead details such as First name, Last name, Lead Status, and Contact into the spreadsheet. Follow the steps below to create your very own custom sidebar:

Step 1: Create a new spreadsheet and go to extensions and click on Apps Script.

Step 2: In Google Apps Script, create a file and paste the following code into it:


function onOpen() {




   .addItem("Display Sidebar", "showAdminSidebar")



function showAdminSidebar() {

 var widget = HtmlService.createHtmlOutputFromFile("Form.html");

 widget.setTitle("Leads Form");



function appendRowFromFormSubmit(form) {

 var row = [form.firstName, form.lastName, form.status,];




Step 3: Next, create a file named Form.html and paste the following code into it:


<!DOCTYPE html>



   <base target="_top">


     function submitForm() {"leadsForm"));





   <h1>Enter Lead details</h1>

   <form id="leadsForm">

     <label for="firstName">First name</label>

     <input type="text" id="firstName" name="firstName"><br><br>

     <label for="lastName">Last name</label>

     <input type="text" id="lastName" name="lastName"><br><br>

     <label for="contact">Contact</label>

     <input type="number" id="contact" name="contact"><br><br>


       <label for="status">Status:</label><br>

       <input type="radio" id="warm" name="status" value="Warm">

       <label for="warm">Warm</label><br>

       <input type="radio" id="cold" name="status" value="Cold">

       <label for="cold">Cold</label><br>

       <input type="button" value="Submit" onclick="submitForm();">
