Why would I need this?

Because an .ics file is unreadable as text and importing it into your real calendar is a heavy way to answer "what is actually in here?" - particularly for a file someone emailed you, or a subscription feed you are not sure you want.

Can I import it into my calendar from here?

No. This reads the file and exports CSV; it does not write to any calendar.

Does it handle repeating events?

It shows what the file declares. Complex recurrence rules with exceptions are where calendar formats get genuinely hard, so check anything unusual against the source.

Is the file uploaded?

No. It is parsed in the page with ical.js. Calendar files are full of names, email addresses and meeting subjects, so that is not a trivial point.

One row for each event in the list as it stands, so the filter and Show past events decide what goes in. Each row has the title, start and end (in UTC, or just the date for an all-day event), location, organiser, attendees, repeat rule, status and the notes, ready to sort and filter in a spreadsheet.

About this ICS calendar file viewer

Opens an .ics invitation or calendar export and lists the events in it — times in your own time zone, locations, attendees and recurrence — and can export them as CSV.

Useful when a calendar attachment will not open, or when you want to see what an export actually contains before importing it. It is free to use, with no account and no upload limit, and it runs entirely in your browser: nothing is uploaded, and while the page stays open, a feature you have already used keeps working offline.

What you can do

Open an .ics calendar file and read its events as a list
Event times shown in your own time zone, using the file’s time zone definitions
Location, organiser, attendees, repeat rule and notes for each event
Cancelled and past events marked as such
Filter events by title, place or notes
Hide past events to see only what is still to come
Export the events to CSV for a spreadsheet

How to read an .ics file

Open the .ics file - an invitation from an email, or an export from a calendar application.
The events are listed in readable form rather than as raw calendar text.
Past events are listed too; untick Show past events to see only what is still to come. A repeating event counts as past only once its last occurrence is over.
Export the events listed as a .csv to open in a spreadsheet - clear the filter and show past events first if you want every one.
