What Our Users Say
Been searching for something like this for months. Our Shopify store processes 500+ orders monthly and this handles everything perfectly. Date formats, tax columns, refunds - all correct.
works good, wish it had batch mode
I was spending 4-5 hours every month reformatting exports manually. This tool paid for itself in the first use. The preview feature helped me verify the mapping before paying.
exactly what i needed thx!!
Super straightforward. Upload, convert, download. No account needed which is nice. Would give 5 stars if they add Xero support.
saved me hours of work
My accountant was so happy when I sent her the converted file. No more back-and-forth about date formats or missing columns. Everything imported correctly on first try.
fast and easy 10/10 would recommend
Been using this for 6 months for monthly reconciliations. Handles all the edge cases - partial refunds, multi-line orders, currency conversions. Very reliable tool.
Good tool, does what it says. Interface could be bit better but conversion quality is excellent. Using it for my 3 Shopify stores.
Switched from A2X to this. Way simpler for my needs - I don't need real-time sync, just clean data once a month. This delivers exactly that.
finally!! something that works with QB desktop!!

Quick Answers
What calendar apps export ICS files?
Google Calendar, Apple Calendar, Outlook, Thunderbird, Yahoo Calendar, and most calendar apps support ICS export. In Google Calendar, go to Settings and use Export to download an ICS file.
Can I convert a file with hundreds of events?
Yes. The tool handles ICS files containing any number of VEVENT entries. Each event becomes one row in the CSV output with all properties extracted.
What columns will the CSV have?
The output includes Subject, Start Date, Start Time, End Date, End Time, All Day Event, Location, Description, Category, Private, Status, Organizer, Recurrence, and UID columns.
Why Convert ICS to CSV?
The Editing Problem
ICS files are structured text that cannot be easily edited, sorted, or filtered. Converting to CSV lets you work with events in any spreadsheet application for analysis or bulk editing.
What This Tool Does
Upload your ICS file exported from any calendar app. The tool parses VEVENT components and creates a flat CSV with separate columns for dates, times, locations, and descriptions.
Multi-Event Support
Handles ICS files with hundreds or thousands of events. Each VEVENT entry becomes one row in the output spreadsheet with all properties extracted.

Frequently Asked Questions
Your data never leaves your device. All files are processed entirely in your browser using client-side JavaScript - no data is stored on our servers or sent anywhere. There's no account to hack, no database storing your files, and no API connections to your bank or accounting software. You upload, convert, download, and we forget it immediately.
No payment or signup required. You can upload your file, see a free preview of the conversion results, and verify everything looks correct before paying anything. If it doesn't work for your files, you haven't wasted any money. We only charge when you're satisfied and ready to download the final converted file.
You can, but free scripts and AI often miss edge cases that break real-world data: missing SKUs, currency formatting quirks, tax calculation errors, or date format mismatches. We have battle-tested validators specifically designed for accounting software imports that catch these issues before they corrupt your books. Plus, you get instant browser-based conversion without installing Python or managing dependencies.
Google Calendar, Apple Calendar, Outlook, Thunderbird, Yahoo Calendar, and most calendar apps support ICS export. In Google Calendar, go to Settings and use Export to download an ICS file.
Yes. The tool handles ICS files containing any number of VEVENT entries. Each event becomes one row in the CSV output with all properties extracted.
The output includes Subject, Start Date, Start Time, End Date, End Time, All Day Event, Location, Description, Category, Private, Status, Organizer, Recurrence, and UID columns.
All-day events are detected from VALUE=DATE parameters or date-only DTSTART values. The exclusive DTEND is adjusted back by one day to show the actual last day of the event.
Yes. After processing, you can download the result as either CSV or Excel (XLSX) format.
In Google Calendar, go to Settings, select your calendar, scroll to Export Calendar, and click the export button. This downloads a ZIP file containing an ICS file.
Recurring events are preserved with their RRULE in the Recurrence column. The tool does not expand recurrences into individual occurrences.
