TableMonitor

About

Keep a pulse on your critical data with TableMonitor—the premium, lightweight background tracker for Google Sheets. 

Whether you are tracking live sales, team updates, operational workflows, or project statuses, TableMonitor runs silently in the background and alerts you the exact millisecond any cell within your selected range changes.

🚀 ZERO SETUP & NO GOOGLE DEVELOPER API REQUIRED
Unlike other trackers that require complex Google Cloud Console setups, Apps Script webhooks, or OAuth2 logins, TableMonitor works out-of-the-box. It leverages your browser's existing active session cookies to securely scan any spreadsheet you have access to. If you can view the sheet in your browser, TableMonitor can track it!

🔔 APPLE-STYLE SYNTHESIZED SOUND ALERTS
Hear your data updates with beautiful, custom-engineered sound notifications inspired by iconic Apple designs. Built entirely on the modern Web Audio API, sound prompts are synthesized in real-time inside Chrome’s offscreen document:
• 🍏 Apple Tritone — The classic, crisp rising iOS chime.
• 💻 macOS Chord — A deep, resonant harmonic sweep.
• 📬 Apple Ping — A high-pitched, crystalline bell ring.
• ⌨️ Apple Click — An ultra-subtle, modern keyboard tactile click.
• And 4 more custom presets (Gentle Chime, Crystal Ding, Retro Synth, Cosmo Pulse) with Master Volume control.

🎯 PRECISION TARGETED CELL RANGES
Prevent alarm fatigue by monitoring only what matters:
• Track entire tabs or lock down to precise cell ranges (e.g. A1:D20, columns A:B, rows 10:15, or single cells like F5).
• The extension translates cell range coordinates and scans only the specified boundary, ignoring all unrelated edits.

🌍 MULTI-LANGUAGE INTERFACE
Switch dynamically between fully-localized English and Ukrainian interfaces with a single click in the Settings tab. Even background logs and relative timers align automatically with your selected language!

🛡️ PRIVACY-FIRST & HIGH PERFORMANCE
• 100% Local Storage: All sheet URLs, change ledger history, and configurations are stored locally on your device (chrome.storage.local).
• Zero external servers: No third-party API integrations, analytics tracking, or user data harvesting.
• Battery & Rate-Limit Optimized: Restricts checks to a smart 10-minute minimum interval, fully complying with Google Sheets quota systems to avoid browser rate limits (429 errors).
