Frequently Asked Questions

How do I convert an Excel file to a calendar?

Upload your .xlsx, .xls, or .csv file, map the columns to calendar fields (date, time, event name, etc.), choose your output format (ICS or Google Calendar CSV), and download. The entire process takes seconds and runs in your browser — no account or installation needed.

Is my data safe? Do you store my files?

Your data never leaves your browser. Excel to Calendar Converter runs 100% client-side using JavaScript — no files are uploaded to any server, ever. Your spreadsheet is processed entirely on your own device.

Which calendar apps are supported?

ICS files work with Apple Calendar, Microsoft Outlook, Thunderbird, and virtually every calendar app that supports the iCalendar standard. The Google Calendar CSV format is specifically designed for Google Calendar's import feature.

What Excel formats are supported?

.xlsx (Excel 2007+), .xls (legacy Excel), and .csv (comma-separated values). Multi-sheet workbooks are fully supported — you can select which sheet to convert.

How do I import the ICS file into my calendar?

Apple Calendar: Double-click the .ics file, or drag it into Calendar.
Outlook: Double-click the .ics file, or use File → Open & Export → Import.
Google Calendar: Go to Settings → Import & Export → Import, then upload the .ics file.
Thunderbird: Use File → Import → Import from file.

Can I convert a class schedule or work roster from Excel?

Yes — any spreadsheet with dates and event names can be converted. University timetables, work shift rosters, training schedules, exam calendars, and meeting lists all work. Just map your columns to the right calendar fields.

What if my spreadsheet has multiple sheets?

If your Excel file contains more than one sheet, a sheet selector will appear so you can choose which one to convert. Each sheet is processed independently.
