CSV-to-ICS Converter is a free and simple tool for converting calendar data from the CSV format into the standard iCalendar (ICS) format. It runs locally on your computer, so you don't need to upload your sensitive calendar data to a website to perform the conversion.

A wide variety of input fields are supported, including fields for event recurrence, reminders, categories, and more. The input fields do not have to be in any specific order in the CSV file. The generated ICS files can be emailed, uploaded to your website, or imported into Google Calendar, Outlook, VueMinder, and many other calendar apps.
