How to Read & Write Data on Google Sheets using Apps Script and PHP

Do you want to read from and write data to Google Sheets using PHP? Sometimes you need to build a flow to programmatically send data to the Google Sheets. You may also be required to print data from Google Sheets. There are 2 possible ways to interact with the Google Sheets and perform read/write operations.

I have tried both options and found Google Apps Script much easier.

To integrate the Google OAuth you require to register your app, build the OAuth flow, store the access token in the database, and keep refreshing it in the background. This process requires resources like a database, Google’s PHP library, HybridAuth library(to manage OAuth), and quite complicated PHP code.

On the other hand, for the Apps Script, you will need to write very little code(which is mostly written in JavaScript) and get a Web APP URL. To this Web App URL, you can send a POST request along with data which then eventually writes to the Google Sheets. Reading data from Google Sheets is also possible by making a GET request to the Web App URL. You won’t require a database and PHP libraries to accomplish the task. You just have to write GET and POST requests using PHP cURL and you’re done.

That being said, let’s take a look at how to read and write data on Google Sheets using PHP and Apps Script. We’ll create 2 Web App URLs. One is for the POST request to write data on a spreadsheet and another is a GET request to read data from a spreadsheet.

Create Web APP URL for POST Request

Head over to Google Drive and create new Google Sheets. You may add your headings on the first row. Our code will append new entries starting from the next row.

Click on Extensions -> Apps Script which will open a new page that has a code editor. Inside the editor, we’ll write a code for both GET and POST requests. Let’s first handle the POST request.

const doPost = (request = {}) => {
  const { parameter, postData: { contents, type } = {} } = request;
  if (type === 'application/json') {
	const jsonData = JSON.parse(contents);

	for (let i = 0; i < jsonData.length; i++) {
	result = {
  	status: 'success',
  	message: 'Rows are added.'

	return ContentService.createTextOutput(JSON.stringify(result));

This code receives the payload and writes it to the connected Google Sheets. Our job is to send the payload from the PHP script. To send the payload we have to generate a Web App URL. For this, save the Apps Script code and click on Run.


It’ll prompt for Authorization. Complete the steps. During the process, you may see a screen where it says Google hasn’t verified this app. Don’t worry about this screen as you’re the one who asks for permission. Click on Advanced and proceed with it.


Once you complete the authorization, click on Deploy -> New deployment from the top right corner. Choose a Web app from the settings icon.


Next, execute the web app as yourself, set access to Anyone, and hit the Deploy button.


In the next window, you’ll get a Web App URL. Copy the URL for the later use.

Create Web APP URL for GET Request

Similar to POST requests, you need to generate a Web APP URL for a GET request. In this case, you don’t need to perform authorization steps as it has been already done.

Write the below Apps Script code to the same editor after the doPost method.

function doGet() {
  const values = SpreadsheetApp.getActiveSheet().getDataRange().getValues();
  return ContentService.createTextOutput(JSON.stringify(values));

After this, set doGet at the function dropdown and perform the Deploy process as mentioned in the previous step.


You’ll get a different Web APP URL for the GET request. Copy this URL.

Now you have 2 Web APP URLs. One is to write data on Google Sheets and the second one is to read data from Google Sheets.

In the next section, let’s see how to handle these GET and POST requests using PHP.

Read and Write Data on Google Sheets Using PHP

To post data on the Google Sheets, you need to JSON-encode the input and send it to the Web APP URL. The Apps Script then automatically appends the entries to the Google Sheets. The below code is written using PHP cURL to send a POST request.


$data = array(
    	'John Doe',
    	'Web Development',
    	'Want to develop a new website.',
    	'Sam Doe',
    	'Game Development',
    	'Want to develop a new video game.',
$payload = json_encode($data);

$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // follow redirects response
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
$response = json_decode($result);
if ('success' == $response->status) {
	echo "Form is submitted successfully.";
} else {
	echo "Something went wrong. Try again later.";

Here, I am passing 2 array elements at a time. You can send as much data as you want. Go ahead and run this PHP script. You should see your records added to the Google Sheets.

Just like a POST request, you can send a GET request and receive data written on Google Sheets.


$ch = curl_init($url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); // follow redirects response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
$response = json_decode($result);

This code will print your data into an array format. You can loop through the array and print the records.
