About Converting CSV to ICS
CSV is a plain-text table format where each line is a row and commas separate columns. Its simplicity makes it the universal exchange format for data between spreadsheets, databases and code. When you need to move away from CSV, the usual reason is simple: no formatting, formulas or multiple sheets.
Converting your CSV spreadsheet to ICS solves that. ICS (iCalendar) is the universal calendar format for sharing events, invitations and schedules. Google Calendar, Outlook and Apple Calendar all import and export it. In practice you gain universal calendar exchange and supports recurring events and invites. PrivConvert runs the whole CSV-to-ICS conversion in server memory and deletes your file the instant the ICS is ready — nothing is stored, logged or reused.
When this conversion helps
- You need universal calendar exchange
- You need supports recurring events and invites
- You need plain text

Tips for best results
- After converting, open the ICS and skim the formatting — complex layouts occasionally need a small touch-up.
- Files up to 250 MB are supported, and you can batch-convert several CSV files at once; each is processed privately and deleted immediately.
