Automate JSON Data Import to Google Sheets with n8n

What this workflow does

This workflow in n8n reads user data from a JSON file and adds that data directly into a Google Sheets spreadsheet.

It helps users stop manually copying data, which takes time and causes mistakes.

The final result is fast, reliable importing of JSON data into Google Sheets, saving hours and reducing errors.

Who should use this workflow

Anyone needing to move user or other structured data from JSON files into Google Sheets regularly will benefit.

It suits data analysts or teams tired of manual copy-pasting and looking for simple automation inside n8n.

Tools and services used

• n8n platform: For creating and running the workflow.
• Read Binary File node: To read JSON file data from disk.
• Move Binary Data node: To prepare binary data into the main stream.
• Google Sheets node: To append rows to a specific spreadsheet using OAuth2 authentication.
• Google Sheets OAuth2 credentials: For secure access to spreadsheet data.

Inputs, process, and outputs explained

Inputs

• A JSON file stored at a set file path (example: /username/users_spreadsheet.json) containing user data.
• Google Sheets spreadsheet ID and range where data should be appended (example range: A:C).
• OAuth2 credentials for Google Sheets API access.

Processing steps

• Read Binary File node reads the JSON file as binary data.
• Move Binary Data node moves binary data to the main data stream so later nodes can access it.
• The JSON data is parsed and formatted inside the Google Sheets node before appending.
• Google Sheets node appends the structured data to the specified spreadsheet and range using secure OAuth2.

Outputs

• The user data appears as new rows in Google Sheets at the chosen range.
• The workflow confirms successful addition or shows errors if any processing fails.

Beginner step-by-step: How to use this workflow in n8n

Importing the workflow

1. Download the workflow file using the Download button on this page.
2. Open your n8n editor.
3. Click the top-left menu, choose “Import from File”, and select the downloaded workflow file.

Configuring after import

1. Add Google Sheets OAuth2 credentials in the Credentials tab if not already set up.
2. In the Read Binary File node, update the filePath to match your JSON file location.
3. In the Google Sheets node, enter the correct sheetId and range where data should append in your spreadsheet.

Testing and Activating

1. Run the workflow once manually to check if the JSON data goes into Google Sheets.
2. If it works, enable the workflow by clicking the “Active” toggle in the top right for production use.
3. Optionally, set a Cron node trigger before the Read Binary File node for running it automatically at intervals.

For users running n8n on their own server, refer to self-host n8n resources to schedule or monitor workflow operations.

Possible problems and solutions

File not found error: Check the JSON file path is perfectly correct. Make sure n8n can read the folder and file.

Google Sheets authentication error: Check the OAuth2 credentials setup in n8n. Reauthorize if expired.

No data appended: Ensure the JSON structure matches the columns expected. Add a Function node before the Google Sheets node to adjust data formatting if needed.

Customizations

• Change the filePath in the Read Binary File node to use another JSON file.
• Adjust the range in the Google Sheets node to append data to other columns or sheets.
• Add a Function node after Move Binary Data to clean or transform JSON data before appending.
• Use a Cron node at the start to automate running this workflow regularly without manual start.
