About the CSV to ICS Converter
The CSV to ICS Converter turns a spreadsheet of events into a single .ics calendar file, matching common column names and reporting every row it skips. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Loading a term timetable into a calendar in one go.
- Publishing a season of fixtures as a subscribable file.
- Turning a rota spreadsheet into calendar entries.
Details
| Required columns | A title and a start date |
|---|---|
| Date format | YYYY-MM-DD only, and deliberately so |
| Optional | Start time, end date, end time, location, description |
| Default times | 09:00 to 10:00 where a time column is missing |
All events land in one file with one calendar header, which is what you want for an import. If you need each event as its own attachment, convert them one at a time with the ICS Event Generator.
Where this tool stops
One event per row, no recurrence, and no attendees. A repeating series belongs in a single event with an RRULE rather than one row per occurrence.
Frequently asked questions
Why will it not accept 03/04/2026?
Because nobody can tell what it means. That is the third of April in Britain and the fourth of March in America, and a calendar tool that guessed would put a portion of your events in the wrong month without saying so. ISO dates — <code>2026-04-03</code> — are unambiguous. In Excel, format the column as <code>yyyy-mm-dd</code> before exporting.
Should I choose floating or UTC?
Floating for anything local: a timetable, a rota, opening hours. Everyone reads 09:00 as 09:00 wherever they are. UTC for anything shared across zones, such as a webinar series, so all attendees see the same moment.
Can I set a different reminder for each event?
Not from the spreadsheet — the reminder applies to every event in the file. Split the list and convert twice if two groups need different reminders.
Is the CSV to ICS Converter free, or is there a paid tier?
It is free, with no account, no trial and no daily cap. Every generators tool on inputtesthub.com works the same way: open the page and use it.
Can you see what I put into this page?
No. The CSV to ICS Converter runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
Who is the CSV to ICS Converter for?
The most common reasons people reach for it: loading a term timetable into a calendar in one go. Publishing a season of fixtures as a subscribable file. Turning a rota spreadsheet into calendar entries. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is there anything the CSV to ICS Converter cannot do?
One event per row, no recurrence, and no attendees. A repeating series belongs in a single event with an RRULE rather than one row per occurrence. Knowing where a tool stops being trustworthy matters more than the cases where it works.
What figures does the CSV to ICS Converter work from?
Required columns is A title and a start date. Date format is YYYY-MM-DD only, and deliberately so. Optional is Start time, end date, end time, location, description. These are printed on the page itself, so you do not have to take them on trust.
Is there a file size limit?
There is no limit set by us, because your file is never uploaded — the only ceiling is the memory your own browser will give the tab. Very large files simply take longer to process, and a phone will give up sooner than a desktop.
