Easy to Follow Guide to Klaviyo Google Sheets Integration

Klaviyo is a go-to marketing automation platform for 100,000+ global companies. It helps e-commerce businesses deliver personalized experiences through its data-driven tools. The platform has quite impressive analytics features and metrics that help businesses determine their next marketing move.

You can connect Klaviyo to Google Sheets and export the data to get a complete view of the marketing performance. Let’s explore the ways to integrate Klaviyo into Google Sheets.

Different ways to integrate Klaviyo into Google Sheets

Klaviyo allows exporting data into .csv files, which can be later imported into Google Sheets. This method requires repeating the manual export-import process every time you need fresh data. Therefore, it is not a feasible method if you’re looking to connect Klaviyo to Google Sheets and integrate the data flow. 

The best part of Klaviyo is its seamless integration ability with other platforms. The availability of API makes it possible to connect it with any other platform or tool. API (Application Programming Interface) is a mechanism that enables the communication between two applications through a common protocol.

Here are the ways to connect Klaviyo API with Google Sheets:

  • ETL tool by No-code and easy-to-follow method to connect Klaviyo to Google Sheets. Requires less technical expertise.
  • Google Apps Script: Programmatic method to pull data from Klaviyo to Google Sheets using Google Apps Script. Demands knowledge of Apps Script.

Both methods use Klaviyo API to integrate Google Sheets. Take reference from the Klaviyo API documentation to learn more about the data you can import.

How to generate Klaviyo API key?

Klaviyo API Key is required to get the Klaviyo data through API. It acts just like a password to authenticate the request.

To get your Klaviyo API Key, log into your account dashboard and follow these steps:

  • On the bottom-left corner of the page, click on your profile and go to Settings.
1 go to klaviyo account settings
  • In the Account Settings, navigate to the API Keys tab, where all your public and private API keys will be listed. We need the private API key to connect Klaviyo to Google Sheets. Click the Create Private API Key button.
2 create klaviyo api key
  • Next, enter the Private API Key Name and select the Access Level, which will be the Full Access Key in our case. Choose Read-Only Key if you want to just import Klaviyo data into Google Sheets. Finally, click Create to get the Klaviyo API Key.
3 define api key access in klaviyo
  • Your Klaviyo API Private Key will be displayed on the screen. Copy the Key and download it for future use.
4 copy download klaviyo api key
  • You can also find the generated API key under the Private API Keys section in Settings > API Keys.

Now, we are ready to go for the Klaviyo Google Sheets integration. You can follow any of the two methods below for successful integration.

Automate Klaviyo Google Sheets integration without coding

Do you want to connect Klaviyo to Google Sheets and import data on schedule? Well, has got you covered! is a data automation and analytics platform that offers an ETL tool to extract data from various sources into destinations such as Excel and Google Sheets. With the help of the JSON connector, you can integrate Klaviyo with Google Sheets and automate the data flow.

Note: In this method, you need to modify the JSON URL and parameters as per Klaviyo API to get the required data. We are not responsible for any errors arising because of misconfigurations or changes in the app’s API. You can request this premium integration at

First, create a account and log into the dashboard. Create an importer and select JSON as the source and Google Sheets as the destination app.

Next, click Proceed and configure the following settings for Klaviyo Google Sheets integration.


  • In the JSON URL, enter the respective Klaviyo API endpoint to get the required data. For example, to get the list of profiles, use the following API endpoint:

Read the Klaviyo API documentation to learn endpoints for different data you can export. 

  • Select GET in the HTTP method.
  • In the Request headers, specify the Klaviyo API key that we generated earlier, and add the revision date of the API endpoint.
    • Authorization – Klaviyo-API-Key {your_private_api_key_here}
    • Revision – 2023-02-22

(Klaviyo keeps updating its API regularly. You need to specify the release date of the API version you’re using in the header. Currently, the latest and stable version is v2023:02:22)

Optionally, you can also specify the URL query parameters, required Columns, and Path in the Source configuration as per the data requirements.

  • Click Jump to Destination Settings to proceed further.


  • In the Account, log into your Google account and authorize access to
  • Select the Spreadsheet in your account where you want to import the Klaviyo data.
  • Next, select the destination Sheet and click Jump to Schedule Settings.
8 configure destination in coupler

Optional destination settings lets you specify the target Cell address/Range for the Klaviyo data import. The default is the A1 cell. You can also choose the import mode from the following:

  • Replace: The old data in the sheet will be replaced by a new one on each refresh.
  • Append: The new data will be added to the sheet on every refresh. Old data will remain intact.

Next, click Continue to proceed with the next section.


  • Enable the Automatic data refresh to update the Klaviyo data in Google Sheets on schedule.
  • Select the Interval of the auto-refresh and choose the applicable Days of the week.
  • Specify the preferred time for the data update and click Save and Run.

Well, that’s Klaviyo Google Sheets integration made easy by Create as many importers as you need by calling different API endpoints to import the desired data!

Connect Klaviyo to Google Sheets using Google Apps Script

Google Apps Script is a JavaScript-based language supported by Google Workspace to integrate various applications. You can use the Google Apps Script to call the Klaviyo API, fetch the required data, and import it into Google Sheets.

This method demands high proficiency in the JavaScript language and working with APIs. Let’s say you want to get all the profiles from Klaviyo into Google Sheets. You can follow these steps to do that using Google Apps Script:

  • Open the Google Sheet where you want to import Klaviyo data and go to Extensions > App Script.
13 open extensions app script in google sheet
  • In the script editor, copy and paste the following code:
function ListProfiles() {
   const API_URL = "";
   const DATA_ENDPOINT = "/v1/people";
   const API_KEY = "Your_Klaviyo_API Key";
   const response = UrlFetchApp.fetch(API_URL + DATA_ENDPOINT + "?api_key=" + API_KEY);
   const content = JSON.parse(response.getContentText());
   const sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1"); // Change Sheet1 to the name of your sheet

  // Create the header row 
  var headerValues = ["ID", "Email", "First Name", "Last Name", "Address 1", "Address 2", "City", "Country", "Region", "Zip", "Title", "Phone Number", "Organization", "Updated"]; // the header row values
  sheet.getRange(1, 1, 1, headerValues.length).setValues([headerValues]); // add the new header row

   // Get existing data in sheet
   const dataRange = sheet.getDataRange();

   const values = dataRange.getValues();

   // Loop through Klaviyo data and update sheet
   for (let i = 0; i <; i++) {
       const id =[i].id;
       // Check if id already exists in sheet
       let existingRowIndex = -1;
       for (let j = 1; j < values.length; j++) { // Start at 1 to skip header row
           if (values[j][0] == id) { // Column 1 contains the id
               existingRowIndex = j + 1; // Add 1 to account for header row
       // If id exists, update other details in same row
       if (existingRowIndex > 0) {
           const rowToUpdate = sheet.getRange(existingRowIndex, 1, 1, 14);
       // If id doesn't exist, add new row
       else {

Remember to replace Your_Klaviyo_API Key in the above code with your Klaviyo Private API Key that we generated earlier.

  • Next, save the script and click Run to execute the code.
14 run script to import klaviyo data into google sheets
  • You may be prompted to authorize the permission to run the script. Click on Review permissions.
