ICS to CSV Converter - 2026 Pricing, Features, Reviews & Alternatives

Someone exports a shared calendar, opens it in Excel and finds one long column of raw text. Or the import into another calendar app works, but every meeting has moved by an hour. ICS to CSV Converter exists for those two moments. It reads .ics and .vcs files on a Windows PC and writes one clean table, and the ICS to CSV step takes the guessing out of time zones, all-day dates and recurring events.

🔍 The problems it solves

Calendar files are text, but not the kind a spreadsheet understands. Long lines are folded, commas are escaped, and a holiday on 5 May is saved as running until 6 May. A naive conversion turns each single-day entry into two days. Time zones are harder still: when the receiving app does not recognize a zone name, it may quietly treat the time as GMT. This program reads the zone definitions packed into the file and picks the rule that applied on each date, so winter and summer meetings each get the correct offset. If a file carries no zone definition, a list of widely used IANA zone names is used instead and the row gets a marker.

📂 Typical scenarios

A coordinator collects one .ics per team member every month to count hours by category. All of them go into one queue and come out as a single deduplicated ICS to CSV export.

An admin prepares a calendar move and wants to inspect the data before importing it anywhere. The Plain template keeps every parsed field, including UID, STATUS, SEQUENCE and X- properties.

A user has an archive of .vcs files from an old phone saved in windows-1251. The encoding is detected and the text comes out readable.

⚙️ What the output looks like

Every ICS to CSV run writes one file. With the Google Calendar template you get Subject, Start Date, Start Time, End Date, End Time, All Day Event, Description, Location and Private, with US-style dates and 12-hour times. The Outlook template follows the column order Outlook asks for. The Plain template writes ISO 8601 timestamps and every property it found, which is handy for audits. Attendees can sit in numbered columns or share one cell, whichever your next tool prefers.

❓ FAQ

Can I export a Google Calendar to CSV?

Google hands you .ics files, one per calendar or a zip with all of them. Add those files here and you get the CSV. Building the table from that download keeps guest lists and repeat rules, which a CSV import back into Google would drop.

How do I export an Outlook calendar to Excel?

Save the calendar as an .ics file, convert it with the Outlook template and open the CSV. That is a short ICS to Excel route, and the header row already matches what Outlook expects.

My events shifted by an hour or two. Why?

The app that imported them probably did not know the zone name and used GMT instead. Here the offset is computed from the zone rules of the file, including daylight saving on that date.

🎁 Free trial

The trial needs no registration and converts the first 10 events per run, so you can test the ICS to CSV output on your own files. Windows 11, 10, 8.1, 8 and 7.
