About ICALENDAR files
The .icalendar file extension stores calendar events, to-do lists, and meeting requests. Apple Calendar, Microsoft Outlook, and Google Calendar use this format to exchange scheduling data based on the iCalendar standard. Users often need to convert .icalendar files because the lengthy extension is less universally recognized than the standard ICS format, causing web browsers and older software to reject uploads. Furthermore, reading raw event data requires a specialized calendar app. The best conversion targets are CSV for spreadsheet analysis, PDF for printing schedules, and ICS for maximum software compatibility. Note that converting to CSV will likely lose complex recurring event rules (RRULEs) and custom timezone data. Although the baseline standard is open, real-world .icalendar files often function as a closed, proprietary format. Vendors heavily inject custom, non-standard properties (like X-APPLE-TRAVEL-ADVISORY). Explain clearly why standard online converters fail to process it: they crash or drop data when encountering these undocumented, proprietary vendor tags. Often only the original software can properly read or export the full data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your ICALENDAR file, detects the exact format, and lets you read the text inside.

The ICALENDAR Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ICALENDAR converter.
