The Google Sheets node offers a wide array of operations for interacting with your data.

Overview of Supported Resources

The Google Sheets node is divided into two main categories of operations:

  • Document Operations: These actions allow you to manage your Google Sheets files themselves. You can:
    • Create a new spreadsheet: perfect for generating new reports or logs on the fly.
    • Delete a spreadsheet: useful for cleaning up temporary files or outdated reports.
  • Sheet Operations: These actions are all about working with the data inside your spreadsheets. You can:
    • Read data from a sheet: Get all rows, a specific range of rows, or even lookup rows based on a specific value.
    • Write data to a sheet: Append new rows, update existing rows, or even clear a sheet entirely.
    • Delete rows or columns: Programmatically remove data from your sheets.
    • Manage tabs (sheets): Create new tabs, duplicate existing ones, or delete them as needed.

Key Node Configuration Options

When you start working with the Google Sheets node, you’ll come across a few key configuration options that are important to understand:

  • Mapping Modes: This is one of the most critical settings in the node, and it determines how your incoming data is mapped to the columns in your Google Sheet. You have three options:
    • Automatically: n8n will try to match the keys in your incoming JSON data to the column headers in your sheet. This is the default and works well for simple workflows, but it can lead to issues if your data isn’t perfectly clean.
    • Map Each Column Manually: This is the recommended approach for production workflows. It gives you full control over how your data is mapped, allowing you to explicitly link each incoming data field to a specific column in your sheet. This prevents errors caused by mismatched column headers or extra data fields.
    • None: This option is for more advanced use cases where you want to provide the data in a specific format that the node can understand without any mapping.
    Screenshot of the Mapping Column Mode option in the n8n Google Sheets node.
    Choose “Map Each Column Manually” for robust and reliable data mapping.
  • Append vs. Update Operation: When you’re writing data to a sheet, you have two main options:
    • Append: This will add a new row to the end of your sheet. This is the most common operation for logging data or adding new entries.
    • Update: This will modify an existing row in your sheet. You’ll need to specify a key column to match on, so n8n knows which row to update.
  • Data Range, Row Index, and Formatting Controls: The node also gives you granular control over how your data is handled:
    • Range: You can specify a specific range of cells to read from or write to using standard A1 notation (e.g., "A1:C10").
    • Screenshot of the Data Location on Sheet option in the n8n node.
      The Range option allows you to target specific cells in your sheet.
    • Row Index: When updating or deleting rows, you’ll often use the row index to specify which row to target.
    • Value Render Mode: This setting allows you to control how the values in your sheet are formatted. You can choose to get the raw, unformatted value, or the formatted value as it appears in the sheet.

✅ Pro Tip Box: Always use “Map Each Column Manually” in your production workflows. This will save you a lot of headaches down the road by preventing row misalignment issues caused by unexpected changes in your incoming data.


Step-by-Step Guide: Setting Up Google Sheets OAuth2 for n8n

Before you can start automating your Google Sheets, you need to set up the proper authentication. This involves creating a Google Cloud project and configuring OAuth2 credentials so n8n can securely access your Google Sheets data. This section will serve as your standalone reference for getting this set up correctly.

✅ Step-by-step:

  1. Visit the Google Cloud Console: Head over to the Google Cloud Console and create a new project. If you already have a project you want to use, you can select that instead.

  3. Enable the Google Drive API: While you’re at it, you should also enable the “Google Drive API.” This is necessary for some of the document operations in the Google Sheets node, such as creating or deleting spreadsheets.
  4. Create OAuth2 Credentials:
    • In the “APIs & Services” section, go to the “Credentials” tab and click on “Create Credentials.”
    • Screenshot highlighting the Create credentials button.
      Start creating credentials for the API.
    • Choose “OAuth client ID.”
    • Screenshot showing the credential type selection screen.
      Select the appropriate credential type.
    • For the “Application type,” select “Web application.”
    • Give your OAuth client ID a name, like “n8n Google Sheets.”
    • Under “Authorized redirect URIs,” add the following URI: https://api.n8n.io/oauth2-credential/callback
    • Screenshot of OAuth client ID configuration.
      Configure the Application type and Redirect URI.
  5. Configure the OAuth Consent Screen:

    The consent screen is what users will see when they authorize your application to access their Google account.

    • Navigate to “APIs & Services” > “OAuth consent screen”.
    • Choose a User Type:
      • Internal: Only for users within your Google Workspace organization.
      • External: For any user with a Google Account, including standard @gmail.com addresses. This is the most common selection.
    • Fill in the required application details: App name, User support email, and Developer contact information.
    • Under “Audience,” note that new “External” apps start in Testing mode. This mode has a critical limitation: refresh tokens expire after 7 days, leading to connection failures. While in testing mode, you must explicitly add the email addresses of authorized testers under the “Test users” section. Add your own Gmail account here to allow yourself to authenticate.
  6. Add Your Credentials to n8n:
    • Now, go back to the “Credentials” tab in the Google Cloud Console and copy your “Client ID” and “Client Secret.”
    • Screenshot showing the Client ID and Client Secret.
      Copy your new Client ID and Client Secret.
    • In your n8n workspace, go to the “Credentials” section and click on “Add credential.”
    • Search for “Google Sheets” and select the “Google Sheets OAuth2 API.”
    • Paste your “Client ID” and “Client Secret” into the corresponding fields.
    • Click “Connect my account” and follow the prompts to authenticate with your Google account.
  7. Test Your Integration: To make sure everything is working correctly, create a new workflow in n8n and add a Google Sheets node. Try to use the “Append” operation to add a new row to a test sheet. If the row is added successfully, you’re all set!

Common Errors FAQ Box:

  • “Redirect URI mismatch”: Double-check that you’ve entered the correct redirect URI in the Google Cloud Console. It should be exactly https://api.n8n.io/oauth2-credential/callback.
  • “Access denied”: Make sure you’ve added the correct scopes to your OAuth consent screen. You need both the spreadsheets and drive scopes.
  • “Error 403: The caller does not have permission”: This usually means you haven’t enabled the Google Sheets or Google Drive API in your Google Cloud project. Go back and make sure both APIs are enabled.


Real Use Case #1: Log Contact Form Submissions to Google Sheets

One of the most common use cases for the n8n Google Sheets integration is logging data from a contact form. This is a simple but powerful workflow that can save you a lot of time and ensure that all your leads are captured in one central location.

Workflow Overview:

  1. Trigger: A Webhook node receives data from your contact form (e.g., name, email, message).
  2. Optional: A Set or Function node can be used to format the values before they’re sent to Google Sheets.
  3. Action: A Google Sheets node with the “Append Row” operation logs each submission to a spreadsheet.

Step-by-step:

  1. Create a Webhook: In your n8n workflow, add a Webhook node. Set the “HTTP Method” to “POST.” This will give you a unique URL that you can use to send data to your workflow.
  2. Configure Your Form: In your website’s contact form, configure it to send a POST request to the webhook URL you just created. Make sure the form fields have names that are easy to identify, like “name,” “email,” and “message.”
  3. Add a Google Sheets Node: Add a Google Sheets node to your workflow and set the “Operation” to “Append.”
  4. Map Your Data:
    • Select your Google Sheets credentials and choose the spreadsheet and sheet where you want to log the data.
    • Set the “Mapping Mode” to “Map each column manually.”
    • Now, you’ll need to map the data from your webhook to the columns in your sheet. You can do this by dragging the output of the Webhook node to the corresponding fields in the Google Sheets node. For example, you would map the “name” field from the webhook to the “Name” column in your sheet.
    • Screenshot showing how to map webhook data to Google Sheet columns in n8n.

✅ Bonus: You can add an IF node to your workflow to add some conditional logic. For example, you could check if there’s any new data to report on, and if not, skip sending the email.


Bonus Use Case: AI Agent + Google Sheets Automation

Now for a more advanced and exciting use case: combining an AI agent with Google Sheets to create an intelligent data logging system. This workflow allows you to log structured data from natural language input, which can be incredibly useful for a wide range of applications.

Scenario: Logging Natural Language Expense Input

Imagine you could just type “I spent $25 on lunch today” into a chat interface and have it automatically logged to your expense tracking spreadsheet. With n8n, an AI agent, and Google Sheets, you can do just that.

Nodes:

  • Chat Trigger: Receives the natural language input from a chat application like Slack or Telegram.
  • AI Agent: Uses a large language model like OpenAI’s GPT or Google’s Gemini to convert the unstructured text into structured JSON data.
  • Set Node: Formats the JSON data for the Google Sheets node.
  • Google Sheets Node (Append Row): Logs the structured data to your spreadsheet.

Output Format:

The AI agent would be prompted to output a clean JSON object like this:

{
  "date": "2025-08-03",
  "amount": 25.00,
  "category": "Food",
  "note": "Lunch"
}

💡 Tip: To ensure that the AI outputs clean JSON, you can use a Code or Set node to sanitize the output before it’s sent to the Google Sheets node. You might need to parse the AI’s response to extract the JSON object or handle any potential formatting errors.


Lookup, Update & Conditional Logic with Google Sheets

Once you’ve mastered the basics of reading and writing data, you can start to explore some of the more advanced features of the Google Sheets node, like looking up and updating rows, and using conditional logic to create more dynamic workflows.

Lookup Row Based on a Value

The “Get Rows” operation can be used to look up a specific row based on a value in one of the columns. For example, you could look up a customer’s record by their email address or a product’s information by its SKU.

Screenshot of the Get row(s) operation in n8n, filtering by an email address.
Use filters to look up specific rows based on a column’s value.

Update Existing Row Using Row Index

Once you’ve found the row you want to update, you can use the “Update” operation to modify its data. You’ll need to provide the row index of the row you want to update, which you can get from the output of the “Get Rows” operation.

Upsert Pattern

A common pattern in data management is the “upsert” pattern, which means “update if it exists, otherwise insert.” You can implement this pattern in n8n by combining the “Get Rows,” “IF,” and “Append/Update” operations:

  1. Lookup: Use the “Get Rows” operation to look for a row that matches your criteria.
  2. If exists → Update: Use an IF node to check if the “Get Rows” operation returned any results. If it did, use the “Update” operation to update the existing row.
  3. Else → Append: If the “Get Rows” operation didn’t return any results, use the “Append” operation to add a new row.

📘 Use case: This pattern is perfect for creating a simple CRM system. You can use it to log new leads or update the information of existing contacts.


Common Pitfalls and How to Fix Them

While the n8n Google Sheets integration is very powerful, there are a few common pitfalls that you might run into. Here’s a quick guide to some of the most common issues and how to fix them:

Problem Solution
Blank values inserted This is often caused by using the “Automatically” mapping mode. Use “Map Each Column Manually” to ensure that your data is always mapped to the correct columns.
Misaligned rows Check that your column headers in Google Sheets match the keys in your incoming data exactly. Even a small typo can cause the rows to be misaligned.
OAuth errors Re-check that you’ve entered the correct redirect URI and added the necessary scopes in the Google Cloud Console.
Append to wrong row Make sure there are no gaps in your sheet, and turn off the “Append” endpoint if you’re not intending to add new rows.
Rate limits hit Google Sheets has a rate limit of 300 requests per minute. If you’re hitting this limit, you can use the “Split In Batches” node to batch your updates and a “Wait” node to add a delay between requests.
Renamed headers If you rename a header in your Google Sheet, you’ll need to reconfigure the Google Sheets node in n8n to reload the columns.

Power Tips for Scaling with Google Sheets

As you start to build more complex workflows, you can use these power tips to scale your Google Sheets integrations and unlock even more possibilities:

  • Use Sheets as a config source: Instead of hardcoding API keys, email addresses, or other configuration values in your workflows, you can store them in a Google Sheet and use the “Get Rows” operation to retrieve them at runtime. This makes it much easier to manage your configurations and update them without having to edit your workflows.
  • Store dynamic logs across workflows: You can create a centralized logging system by having all of your workflows append their logs to a single Google Sheet. This makes it easy to monitor your workflows and debug any issues that arise.
  • Visualize logs with Google Data Studio or Looker Studio: Once you have your logs in a Google Sheet, you can connect it to a data visualization tool like Google Data Studio or Looker Studio to create interactive dashboards and reports.
  • Parse nested JSON: If you’re working with complex nested JSON data, you can use a Function or Code node to parse it and extract the data you need before writing it to your sheet.
  • Use Sheets + OpenAI for AI-assisted audits: You can combine the power of Google Sheets and AI to create an automated data auditing system. For example, you could have an AI agent read through your data and flag any anomalies or inconsistencies.
