Everything You Need to Turn Sheets Into APIs
Stop building backends for simple data collection. RowSink gives you production-ready endpoints without the production complexity.
Core Features
Everything you need to get started, built for simplicity and reliability.
Instant Setup
Add your Google Sheet, get a unique endpoint URL, start receiving data. No servers, no deployment pipelines, no infrastructure to maintain.
Smart Schema Evolution
Just send JSON. Columns are created from your keys and preserved for consistency. No manual mapping, no schema definitions—your sheet grows as your data evolves.
Your Data, Your Control
Data flows directly to your Google Sheet. We never store spreadsheet content. You own the sheet and the data—always.
And So Much More
Powerful features that make your life easier, without adding complexity.
Real-Time Sync
Data appears in your sheet as it arrives. Requests are queued and processed without blocking—no delays, no manual refresh.
Automatic Timestamps
Every row gets a timestamp (column A by default), so you always know when each record arrived.
API Key Authentication
Protect endpoints with an API key. Enable per spreadsheet for granular control over who can write.
Standard HTTP
POST from any HTTP client—curl, fetch, axios, or any library. JSON or form-encoded; no proprietary protocols.
Works Everywhere
Webhooks, forms, IoT devices, mobile apps, serverless functions—if it can POST, it can send data to your sheet.
Reliable & Scalable
Built on Google Sheets. Rate limits and queues keep things stable; you get predictable behavior at scale.
Spreadsheet Capacity Monitoring
Built-in tool to check how close your sheet is to the 10 million cell limit—no surprises.
Request Queue & Log
See queued requests and their status in the dashboard. Inspect successes and failures without leaving RowSink.
Nested Array Unwinding
Automatically expand nested JSON arrays into separate rows. Perfect for processing orders, line items, or complex nested payloads.
AI Agent Ready
Optimized for tools like Cursor and Claude. RowSink adapts as your AI-generated app’s schema drifts, keeping ingestion stable.
