CSV to ICS Converter turns a spreadsheet of events into an iCalendar (.ics) file that imports cleanly into Google Calendar, Outlook or Apple Calendar.
Everything runs in the browser: the CSV is parsed on your device and never uploaded. Column mapping is auto-detected but fully editable, you see a preview of the first five events before downloading, and the output carries real VTIMEZONE definitions rather than naive local times — so a 9am meeting stays 9am after import.
It also works in reverse. ICS to CSV turns a calendar export into a spreadsheet with one row per event, and the standalone ICS Viewer lets you read any .ics file — grouped by date, with all-day and recurring badges — without importing it into a calendar first.
Free, no signup, no watermark.
