Device & OS
not provided

Verify your organization's privacy and security policies regarding third-party calendar conversion tools before exporting and uploading sensitive calendar data.

Solution 1Recommended

Export as ICS and Convert to CSV via a Trusted Tool

Since Outlook on the web only provides ICS exports, you must first download the ICS file and then convert it using a trusted converter or calendar application.

Spreadsheet software does not natively convert ICS files into structured rows and columns. Using a dedicated ICS-to-CSV conversion tool bridges this gap.

1
Publish or Export the ICS File

Log in to Outlook on the web, click the Settings (gear) icon, navigate to Calendar > Shared calendars, and use the 'Publish a calendar' section to generate an ICS link or download the file.

2
Convert the File

Upload the downloaded ICS file to a trusted, secure online ICS-to-CSV converter, or import it into a desktop calendar application (like Google Calendar or Thunderbird) that supports exporting directly to CSV.

3
Open the CSV in a Spreadsheet

Download the resulting CSV file and open it in your preferred spreadsheet software to view your calendar data structured by date, time, and event details.

Frequently Asked Questions

Why doesn't Outlook on the web let me export directly to CSV?

Outlook on the web is designed primarily for quick calendar sharing and syncing, which utilizes the universal ICS standard. The direct CSV export functionality is currently reserved for the fully-featured Outlook desktop application.

Can I open an ICS file directly in Excel or WPS Spreadsheet?

While you can technically open an ICS file in a text or spreadsheet editor, the raw data will not be automatically organized into usable rows and columns. You must parse or convert the ICS file to CSV first for a structured view.

Are online ICS to CSV converters safe to use?

Many popular converters are safe, but uploading files to third-party servers always carries some risk. You should read their privacy policies carefully and avoid using them if your calendar contains sensitive corporate or personal information.
