How to Turn a Google Sheet into a REST API (in 1 minute)

If you’ve ever wanted to connect your Google Sheet to your app or fetch its data as JSON — you’re in the right place.
In this tutorial, we’ll show you how to turn any Google Sheet into a live REST API in just one minute using SheetToAPI.

⚙️ Why Convert a Google Sheet into an API?

Google Sheets is one of the most accessible databases in the world.
You can use it as:

• a lightweight CMS for your website,
• a simple database for your prototype,
• or a live data source for dashboards and apps.

Turning it into an API allows you to:

• Fetch your data as JSON
• Use it in your frontend (React, Next.js, Vue, etc.)
• Update your app in real time — without redeploying

🚀 Step-by-Step: Convert Google Sheet to API

Here’s how to create a live REST API endpoint from your Google Sheet.

🧩 Step 1: Prepare Your Google Sheet

1. Open your Google Sheet.

2. Decide how your API will access the sheet:

   • Read-only GET requests (default):
     Click Share → Anyone with the link → Viewer.
     This allows SheetToAPI to fetch data without exposing editing rights.

   • Private access via service account:
     Instead of public access, you can give permissions to:
     sheettoapi-service@sheet-to-api-477722.iam.gserviceaccount.com
     This is safer for sensitive data.

3. If you plan to use POST endpoints (write data), make sure the service account or user has Editor permission.

4. Copy your Spreadsheet ID from the URL:

⚡ Step 2: Paste It Into SheetToAPI

Visit sheettoapi.com and paste your Spreadsheet ID into the input field.
Within seconds, you’ll get a public API endpoint like this:

GET https://api.sheettoapi.com/api/v1/data/{endpoint-name-in-your-dreams}

That’s it — your Google Sheet is now a live JSON API!

📡 Example: Fetching Your Sheet as JSON

Use this endpoint in your frontend, backend, or mobile app. You need to add your ApiKey in to headers(x-api-key).

JavaScript Example:

fetch('https://api.sheettoapi.com/api/v1/data/{endpoint-name-in-your-dreams}')
.then(res => res.json())
.then(data => console.log(data));

.NET Example:

using var client = new HttpClient();
var response = await client.GetStringAsync("https://api.sheettoapi.com/api/v1/data/{endpoint-name-in-your-dreams}");
Console.WriteLine(response);

🧠 Bonus: Filter & Query Data

SheetToAPI also supports query parameters for filtering:

GET api/v1/data/sheets/{endpoint-name-in-your-dreams}?column=Status&value=Active

Perfect for dashboards, search features, or dynamic websites.

🌐 Use Cases

Here are some creative ways users are leveraging this feature:

• Dynamic product lists for ecommerce prototypes
• Updating content on static websites
• Simple data source for AI & automation tools
• Connecting Google Sheets to tools like Make, Zapier, or Notion

🔒 Is It Secure?

Yes — you can control who accesses your data.
With SheetToAPI, you can:

• Enable private sheets (only accessible with an API key)
• Rotate tokens at any time
• View access logs from your dashboard
