How do I open an .ics file without adding it to my calendar?

Drop it on this page. Phones and Outlook usually offer only to import an .ics file, which adds every event to your calendar. Here you see the events as a list first, so you can check them, keep just one, or export them, and nothing is added anywhere.

Which time zone are the times shown in?

In your device's time zone by default, so an invitation from another country shows when it happens for you. Switch to "Each event's own time zone" to see the times as the organiser wrote them. Times written without a zone (floating times) are shown as written in both modes.

Can I convert an ICS file to Excel?

Yes. "Download CSV" gives one row per event with title, start, end, all-day flag, time zone, location, description, repeat rule, organiser, attendees, categories, status and link. It opens in Excel and Google Sheets with accents and non-Latin text intact. Search first to export only the events that match.

How are repeating events shown?

Once, on their first date, with a summary such as "Every week on Monday, Wednesday · 12 times". Rules the summary cannot describe exactly are shown with the original rule next to them. "Save this event" and "Add to Google Calendar" keep the repeat rule.

Is my calendar uploaded?

No. The file is read by this page in your browser and nothing is sent to a server. "Add to Google Calendar" opens Google's own page with that one event filled in, only when you press it; the event is saved only if you confirm it there.

Yes. Every tool is free to use, with no account and no credit card. The work runs on your device rather than on our servers, which is what keeps it free to run.

Are my files uploaded?

No. Your files are opened and processed inside your browser and are not sent to LibraTool. Some tools first download a processing engine or AI model to your browser; that download contains no data of yours.

Does it work on mobile?

Yes. It runs in current mobile browsers on iOS and Android, with nothing to install. Very large files can be slow or run out of memory on a phone, so use a computer for those.

How It Works

The page reads the iCalendar text in your browser: it joins folded lines, reads each event and task with its dates, durations, time zone and repeat rule, and converts times with a known zone to yours using the browser's own time-zone data. Nothing is fetched and nothing is sent.

1
Open the file
Drop one or more .ics files, or press "Browse files". "Try a sample" opens a made-up team calendar.
2
Read the events
Events are listed day by day in your time zone. Tap one to see the description, organiser, attendees and their replies, reminders and the repeat rule.
3
Find what you need
Search titles, places and people, hide past events, or switch to each event's own time zone.
4
Save or share it
Save one event as its own .ics, add it to Google Calendar, download everything as CSV, or print the list or save it as PDF.

Your calendar is read in this browser. The file is never uploaded.
