Why Convert ICS to CSV?

The Editing Problem

ICS files are structured text that cannot be easily edited, sorted, or filtered. Converting to CSV lets you work with events in any spreadsheet application for analysis or bulk editing.

What This Tool Does

Upload your ICS file exported from any calendar app. The tool parses VEVENT components and creates a flat CSV with separate columns for dates, times, locations, and descriptions.

Multi-Event Support

Handles ICS files with hundreds or thousands of events. Each VEVENT entry becomes one row in the output spreadsheet with all properties extracted.
