Turn a CSV list of events into an iCalendar (.ics) file you can import into Google Calendar, Outlook, or Apple Calendar.
CSV to iCal lets you turn event spreadsheets into calendar-ready ICS files in seconds. Instead of typing each date and time manually, you upload your CSV file, customize a few options, and download a calendar file that works with Google Calendar, Outlook, and Apple Calendar. Whether you have a list of meetings, holidays, or scheduled events, this tool handles the heavy lifting of date parsing and formatting so you can focus on your schedule. It’s the simplest way to convert csv to ics without complex software.

“Just drag your event spreadsheet into the box, pick a reminder time, and download your calendar file.” That’s all it takes to generate ical from csv and get your events into any calendar app.
Turn hundreds of spreadsheet rows into calendar events without manual entry. This tool handles bulk processing so you can import entire schedules at once.
Add default alarms directly during conversion with the reminder dropdown. Choose from options like 15 minutes, 1 hour, or even a day before each event.
Download individual ICS files or a ZIP of all calendars. Whether you need one file or many, the output is ready in a single click.
Supports multiple date formats (ISO, US, EU) and time zones. The tool automatically interprets your dates so you don't have to reformat your spreadsheet.
Combine multiple CSV files into one ICS calendar when needed. Perfect for consolidating events from different sources into a single calendar file.
Use the sample CSV template to match the exact column headers the tool expects – this prevents parsing errors.
For all-day events, leave the time columns blank and mark the “All Day” column as TRUE to keep the date correct.
Check the merge option if you’re uploading multiple files to avoid downloading separate ICS calendars for each one.
The ICS file generated by this tool contains everything from your CSV: event titles, start and end times, locations, descriptions, and any reminders you selected. The tool automatically distinguishes between all-day events and timed events based on your data. It also handles timezone declarations so your events appear at the correct time when imported, no matter which calendar app you use. The result is a clean, import-ready calendar file that preserves every detail from your original spreadsheet.

The raw decoded bytes may contain non‑textual data. This is normal for binary‑encoded Base64 strings.
