About this tool

This site offers one focused utility: a converter that turns CSV or spreadsheet rows into an iCalendar (.ics) file you can import into Google Calendar, Apple Calendar or Outlook. It exists because moving many events into a calendar by hand is slow, and most alternatives either lock you into a single vendor or require uploading your data.

The converter is built and maintained by Marcio, an independent developer who makes small, single-purpose web tools. The guiding principles are simple: it should do one job well, run entirely in your browser so your data stays private, and never ask you to sign up for anything.

How it is funded

The site may display advertising to cover hosting costs. Ads never change how the tool works, and no event data is shared with advertisers — the conversion happens locally on your device.
