Automated Google Calendar Event Creation

Intelligent workflow automation transforming manual calendar entry into a hands-free, reliable pipeline

Automated Google Calendar Event Creation

ABOUT THIS PROJECT

The client frequently received .ics files containing multiple meetings and reminders, requiring manual upload into Google Calendar. This created repetitive work, risk of duplicate events, missed entries, and no error tracking system. They needed a hands-free solution that could process .ics files instantly, reliably, and safely with automatic duplicate prevention and error handling.

Result:

The automated system completely eliminated manual event entry work. The workflow processes .ics files instantly, prevents duplicates through intelligent matching, handles errors gracefully with isolated event processing, and performs autonomous file cleanup. The client now enjoys a fully automated, self-maintaining event processing pipeline that operates with minimal supervision and provides instant alerts on any failure points.

SnakeScript's Automation Solution

We developed a robust Make.com workflow that intelligently processes .ics files from detection to cleanup. The system monitors a dedicated Google Drive folder, parses iCalendar files using JavaScript, converts them to structured JSON events, and creates calendar entries with intelligent duplicate prevention. The workflow ensures atomic processing—each file is processed exactly once with complete error isolation, preventing cascading failures and maintaining data integrity throughout the pipeline.
The workflow features intelligent duplicate protection at both file and event levels. Using Make.com Data Store, the system prevents double processing of the same file by checking file IDs before processing. For events, it performs intelligent matching based on start time, end time, summary, and description. If duplicates are detected, the system sends alerts and skips creation, ensuring a clean calendar without redundant entries.

Safety & Reliability Features

The system is built with enterprise-grade reliability features including duplicate file protection via Data Store, event-level error isolation to prevent cascading failures, conditional file deletion only after full success, complete cleanup logic to avoid stale records, and instant error notifications with detailed context. This ensures atomic processing with no partial or inconsistent results.
