Welcome to SheetsJSON - Transform Your Spreadsheets into APIs

We’re thrilled to announce the public launch of SheetsJSON – a platform that transforms your Google Sheets into fully functional JSON APIs in seconds.

Why We Built This

As developers, we’ve all been there: you need a quick backend for a prototype, a simple data source for a mobile app, or a way to let non-technical team members update content without touching code. The traditional path involves setting up databases, writing CRUD endpoints, and managing deployments.

But what if your data is already in a Google Sheet? What if your team is already comfortable editing spreadsheets? That’s where SheetsJSON comes in.

How It Works

Getting started is incredibly simple:

Connect your Google account – We use secure OAuth to access only the sheets you explicitly share with us.
Select a spreadsheet – Choose any Google Sheet from your Drive.
Get your API endpoint – Instantly receive a unique URL that returns your sheet data as clean JSON.

That’s it. No servers to configure, no databases to manage, no code to write.

What You Can Build

Our users are already building amazing things:

Content Management – Let marketing teams update website content through familiar spreadsheets
Product Catalogs – Manage inventory and pricing in sheets, consume via API in your store
Event Listings – Keep event data in sheets, display beautifully on your website
Configuration Files – Store app settings in sheets for easy updates without deployments
Prototypes – Build MVPs with real data in hours, not weeks

Features You’ll Love

Real-time Sync

When you update your spreadsheet, your API reflects those changes instantly. No manual syncing required.

Flexible Querying

Filter, sort, and paginate your data using simple query parameters. Get exactly what you need.

Secure by Default

Every API comes with authentication via API keys. Control who can access your data and set rate limits.

Developer-Friendly

Clean JSON output with proper data types. Comprehensive documentation. CORS enabled out of the box.

Full CRUD Support

With our Pro plan and above, you get complete write API access:

POST – Add new rows to your sheets
PUT – Update existing rows by row number
DELETE – Remove rows from your sheets

This means you can build full applications with SheetsJSON as your backend – not just read-only displays.

What’s Next

We’re continuing to improve the platform:

Webhooks – Get notified when data changes (coming soon)
Custom domains – Use your own domain for API endpoints
Advanced transformations – Reshape data before it leaves our servers
