Overview

What Is ICS to CSV Conversion?

ICS to CSV conversion extracts calendar events and todos from iCalendar (.ics) files and transforms them into spreadsheet formats like CSV, JSON, or Excel. The ICS format is the universal standard for calendar data exchange, but spreadsheets are often easier to work with for analysis, filtering, and importing into other tools.

Common reasons to convert include analyzing meeting patterns, migrating between calendar platforms, importing events into project management tools, creating billing records from appointment data, and archiving calendar history in a portable format.

Our tool parses VEVENT and VTODO components from your ICS file on your device — nothing is uploaded. It extracts key fields like summary, start/end dates, location, description, status, organizer, categories, and priority, then lets you download the structured data as CSV, JSON, or XLSX.

The tool works with exports from Google Calendar, Microsoft Outlook, Apple Calendar, Thunderbird, Fastmail, and any other application that produces standard ICS files. It handles recurring event definitions, timezone-aware dates, and files containing thousands of events.

FAQ

FAQ

Frequently asked questions about the ICS to CSV converter

Q1. What is an ICS file?
An ICS (iCalendar) file is a universal calendar format used by Google Calendar, Apple Calendar, Outlook, and many other apps. It contains events (VEVENT), todos (VTODO), and other calendar data in a structured text format. Files typically have a .ics or .ical extension.
Q2. Is my calendar data safe?
Yes. All parsing and conversion happens entirely on your device. Your .ics file is never uploaded to any server. We have no access to your calendar data — close the tab and nothing remains.
Q3. What fields are extracted from my ICS file?
The tool extracts Type (Event/Todo), Summary, Start Date, End Date, Location, Description, Status, Organizer, Categories, Priority, and URL from each VEVENT and VTODO component in the file.
Q4. Can I convert an ICS file with both events and todos?
Yes. The tool parses both VEVENT and VTODO components. You can use the filter buttons to export all items, events only, or todos only. The filter applies to both the preview and the downloaded file.
Q5. What's the difference between CSV, JSON, and XLSX?
CSV is a plain text format with comma-separated values — ideal for importing into spreadsheets, databases, or scripts. JSON is a structured data format preferred by developers and APIs. XLSX is the modern Excel workbook format with formatting support, suitable for direct use in Microsoft Excel or Google Sheets.
Q6. How are dates formatted in the output?
Dates are formatted in a human-readable format (e.g., 'Jan 15, 2025, 2:30 PM'). The original ICS format uses compact timestamps like 20250115T143000Z, which the tool automatically converts.
Q7. What's the maximum file size supported?
There is no fixed limit. Since everything runs on your device, the only constraint is your browser's memory. Calendars with thousands of events convert smoothly; very large files (hundreds of thousands of events) may take a moment longer.
Q8. Does it work with Google Calendar / Outlook / Apple Calendar exports?
Yes. Any standard ICS file exported from Google Calendar, Microsoft Outlook, Apple Calendar, Fastmail, Thunderbird, or any other calendar application is fully supported. The ICS format is an open standard (RFC 5545) used universally.
