ICS to CSV Converter Software

📅 ICS to CSV Converter reads .ics and .vcs calendar files on a Windows PC and writes them into a single CSV table ready for Excel or Google Sheets. Drop a whole folder onto the file list and every calendar inside is parsed according to RFC 5545, with VEVENT, VTODO and VJOURNAL components all handled. Time zone offsets come from the VTIMEZONE block in each file, not from a name lookup, so a meeting booked in Berlin at 9:00 stays at 9:00 in the output. Files never leave your local disk.

ℹ️ The trial version of ICS to CSV Converter processes up to 10 events per run, giving you enough data to verify parsing accuracy and confirm the chosen template fits. Purchasing a license unlocks unlimited conversion.

👍 Top 🔟 reasons to choose ICS to CSV Converter Software

• 1️⃣ VTIMEZONE rules are computed from STANDARD and DAYLIGHT sub-components, with TZOFFSETFROM and TZOFFSETTO applied for the date of each event, so January and July offsets differ when they should.
• 2️⃣ All-day events stay on their day. The exclusive DTEND boundary defined by RFC 5545 is converted back, and DURATION values in ISO 8601 form expand into real end times.
• 3️⃣ RRULE and RDATE are kept raw, and a readable column appears beside them: "Every 2 weeks on Mon, Wed, until 2026-12-31."
• 4️⃣ Three output templates ship ready to use: Google Calendar, Outlook Calendar with its strict 19-column header, and Plain Full ISO with every parsed field.
• 5️⃣ Legacy vCalendar 1.0 (.vcs) files exported from old Outlook, Nokia or Sony Ericsson phones are accepted alongside modern .ics, with windows-1251 and other legacy encodings decoded automatically.
• 6️⃣ Attendees carry CN, ROLE and PARTSTAT, and the Outlook template splits them into Required and Optional columns.
• 7️⃣ Duplicates collapse by UID and RECURRENCE-ID, with SUMMARY plus DTSTART as the fallback key when UIDs are missing.
• 8️⃣ Output uses UTF-8 encoding with BOM header and RFC 4180 quoting, so Excel opens Cyrillic or CJK text on a double-click.
• 9️⃣ Batch mode walks subfolders recursively, and multi-calendar exports holding thousands of events in one file split into individual rows.
• 🔟 Everything runs locally on your machine. No registration is required and nothing is transmitted to any remote server.

❓ Who uses ICS to CSV Converter Software

• ✅ Schedulers and ops coordinators who need hours and categories per person as rows they can pivot.
• ✅ IT admins migrating mailboxes or merging shared calendars, who want an inspectable step between export and import.
• ✅ Anyone with a stack of .ics invitations or a personal calendar export who simply wants the data in a spreadsheet.

Calendar exports can be handled just as well by ICS to CSV Converter Software on Windows Store.

❓ Frequently asked questions

❔ Can I batch convert ICS files to CSV?
💡 Yes. Drag a folder onto the file list and the ICS to CSV Converter walks subfolders, picking up every .ics and .vcs file. The whole queue lands in a single Calendar.csv.

❔ My events shifted by an hour. What happened?
💡 Something read the time zone by name instead of by its rules. This program reads the VTIMEZONE block and applies the daylight rule in force on each event's date.

❔ Why does Outlook refuse to import my calendar CSV?
💡 Outlook demands an exact header row whose column names match the language Outlook runs in. The Outlook template writes that header for you.

❔ Does the ICS to CSV Converter handle .vcs files from old phones?
💡 It does. The vCalendar 1.0 branch decodes per-property CHARSET and QUOTED-PRINTABLE encodings, including archives in legacy code pages.
