If you regularly work with calendar files or need to perform bulk conversions, a dedicated ICS conversion tool is generally a more practical option. One solution you can consider is SysTools ICS Converter Tool. It supports batch conversion of ICS files into multiple output formats while preserving important calendar information such as event subject, start and end date, location, attendees, recurring events, reminders, and descriptions. It also eliminates the need to import each file into a calendar application before converting it.

If your requirement is simply a one-time conversion of a few files, the manual approach may be sufficient. But for larger workloads or professional use, using a specialized converter can save considerable time and help maintain data accuracy during the conversion process.
