Common Questions
Is my data stored on your servers?
No. Conversions happen in your browser and your files never leave your device — except in the AI converter, which uploads your file so a model can read it. Even there the file is discarded as soon as the events come back and is never stored.
What file size limits exist?
Files up to 50MB are supported for optimal performance on most devices.
Which calendar formats are supported?
ICS (iCalendar), CSV, and Excel (XLSX/XLS) formats are fully supported for conversion.
Troubleshooting Tips
File won't convert?
Check if your file is a valid ICS/CSV/Excel format. Try opening it in a text editor first.
Missing event information?
Some calendar fields may not be supported in the target format. Check our format guides for details.
Browser compatibility issues?
Use a modern browser (Chrome, Firefox, Safari, Edge) with JavaScript enabled.
