Why We Created This Tool
Managing schedules, tracking meeting durations, or analyzing billable client hours often requires opening calendar data in spreadsheet software like Microsoft Excel or Google Sheets. However, standard calendar files (.ics and .ical) are structured for calendar apps, not spreadsheets.
Most traditional file conversion tools force users to upload their calendar files to unknown web servers. Because calendars contain sensitive info—such as client names, meeting notes, phone numbers, and location addresses—uploading them creates unnecessary privacy risks.
We created ICS to CSV Converter to solve this problem: a free tool that processes your calendar files entirely inside your own web browser. Your calendar data never leaves your device.
