Create an ICS file from text or Excel
With this tool you can create an ICS file without a calendar app and without signing up: write one event per line (or paste cells from Excel), optionally choose repeat and reminder – and download a calendar file that iPhone, Android, Google Calendar and Outlook import directly.

How it is calculated
An ICS file is a calendar format (iCalendar, RFC 5545) that every common calendar app imports: iPhone, Android, Google Calendar, Outlook, Thunderbird. Here you create one from a simple text list.
How to write the events
11/3/2026 2:30pm Dentist– event at 2:30 pm, one hour long.11/3/2026 2:30pm-3:15pm Dentist @ Office– with end time and place.12/24/2026 Christmas Eve– without a time it is an all-day event.- Several events: just use several lines. Cells from Excel (date, time, title, place side by side) can be pasted too. ISO dates like 2026-11-03 work as well.
Repeat and reminder
Choose daily, weekly, every two weeks, monthly or yearly and the number of events. The tool writes a recurrence rule (RRULE) into the file and your calendar app creates the single events. Reminders (VALARM) fire before the start; for all-day events at 9 am on the day itself.
Time zone and privacy
Events with a time are saved without a fixed time zone (“floating time”). They apply wherever you import the file, so 2:30 pm stays 2:30 pm. That is ideal for personal events; for online meetings across time zones use an invitation from your calendar app instead. Everything stays in your browser.
Frequently asked questions
How do I create an ICS file?
Enter events as text lines (date, time, title) and click “Download ICS file”. Then open the file in your calendar app and choose “Import”.
Can I create an ICS file from Excel?
Yes. Copy the cells (date, time, title, place side by side) from Excel and paste them into the field. Tabs and semicolons are detected automatically.
Can one ICS file hold several events?
Yes, every line becomes its own event. Up to 500 events per file are possible.
How do I open an ICS file on an iPhone or Android phone?
Tap the file (from mail, downloads or Files) and choose “Add all” or “Import”. In Google Calendar on a PC use Settings and Import.
How do I make a repeating event?
Pick the rhythm and number of events under “Repeat”. Every event in the list then becomes a series, for example a birthday that repeats yearly.
Which time zone does the file use?
None fixed: times apply in your calendar’s time zone. An event at 2:30 pm stays at 2:30 pm there, even when you travel.
