CSV to Calendar Converter

How to convert a CSV file to a calendar

Upload your CSV file, map each column to the corresponding calendar field (date, time, event name, location, description), choose your preferred output format, and download. The entire process runs in your browser — your data stays on your device.

What CSV format do I need?

Any CSV file with a header row works. Your file should contain at least a column with dates and a column with event names. Common additional columns include:

• Start time / End time — for timed events
• Duration — alternative to end time (in minutes)
• Location — venue, room, or address
• Description — notes or details about the event
• URL — link associated with the event

Column names don't need to match exactly — the tool auto-detects common header names and lets you manually adjust the mapping.

Output formats

• ICS (iCalendar) — works with Apple Calendar, Outlook, Thunderbird, and any iCalendar-compatible app
• CSV (Google Calendar) — formatted specifically for Google Calendar's import feature

Common use cases

Class schedules exported from student portals, work rosters from HR systems, event lists from databases, conference schedules, training timetables — if it's a CSV with dates, it can become a calendar.
