How to use iCalendar File Inspector

Inventory a supplied calendar file as literal data. Unknown properties, timezone references and recurrence declarations remain visible instead of being silently interpreted or imported.

  1. Enter local file.
  2. Choose the settings for icalendar file inspector, then run the tool.
  3. Review the result and any limitations before copying or downloading it.

Common questions

Does a listed event mean it has been added to my calendar?

No. The tool only reads the selected file and creates a separate local report.

Is this input sent to a server?

No. The application processes this input inside your browser tab and does not save it to persistent storage.
