Extract text from iCalendar files (ICAL)
To convert ICAL calendars to another format, you need Microsoft Outlook or other Data software.
To convert other file formats to the "Internet Calendaring Data" file type, you need software like Microsoft Outlook or a similar tool.
The .ICAL file is a plain-text format used to store and exchange calendar scheduling data, adhering to the iCalendar standard (RFC 5545). These files contain structured event details such as start times, end times, locations, alarms, attendee lists, and free/busy data. They are heavily utilized by enterprise environments like Microsoft Exchange Server and standard email clients like Microsoft Outlook, Apple Calendar, and Google Calendar.
Despite being an open industry standard, the .ICAL format frequently causes synchronization headaches. Different software ecosystems often misinterpret the text rules for complex recurring events and custom time zones. Furthermore, the format is practically unreadable for bulk data analysis. You cannot easily audit a company schedule, tally working hours, or share a visually clean itinerary using raw .ical text.
To overcome these limitations, converting .ICAL to CSV is highly recommended. A CSV spreadsheet allows you to sort, filter, and audit calendar events in Microsoft Excel. Converting to PDF is the best option for generating fixed, printable event lists for non-technical users. Developers often convert .ICAL to JSON to securely parse and feed schedule data into custom web applications. Be aware that converting away from a calendar-specific format means you will lose active alarms, automated RSVP capabilities, and recurring event algorithms.
While .ICAL is theoretically just text, its strict line-folding rules and nested syntax (BEGIN:VCALENDAR...END:VCALENDAR) make manual editing highly dangerous; a single missing character can permanently break the import process. If your file is throwing errors or you cannot natively open it, just drag and drop your file onto convert.guru to identify the format, inspect the raw data structure, and convert it when possible to a standard spreadsheet or document format.
Convert.Guru analyzes your ICAL file, detects the exact format, and lets you read the text inside.
Users also converted ICS, ZIP, CSV, XCAL, XLSX, ICALENDAR, PDF, CAL, JSON, TXT, DAT, ACSM and EDB files.
If you want to convert ICAL file to CSV, ICS, PDF, JSON, XLS, TMP, TEMP, CACHE, LOG, BAK, OLD or NEW, you can use Microsoft Outlook or similar software from the "Calendar Event Scheduling Data" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to ICAL, try Microsoft Outlook or another comparable tool in the "Calendar Event Scheduling Data" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ICAL converter.
