Drop CSV files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the ICS, or download everything as one ZIP if you converted several files.
The CSV to ICS converter is part of this page and runs inside your browser. Your spreadsheets are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
A schedule kept in a spreadsheet, such as a class timetable, a rota or a list of deadlines, can be imported into Google Calendar, Apple Calendar or Outlook as an ICS file. Each row becomes one event.
Events are written as iCalendar 2.0. The CSV needs a Summary (or Title) column and a Start date column, written like 2024-03-10 or 2024-03-10T09:00:00; a date that cannot be read stops the conversion and names the row. Files up to 100 MB are accepted.
CSV is a table written as text: one row per line, values separated by commas. Every spreadsheet and database can import and export it, but it holds one sheet only and no formatting, formulas or data types.

No. The CSV to ICS conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
The values are kept. Anything ICS has no way to express, such as formatting, formulas or nesting, is simplified or left out.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the CSV file, press Convert and save the ICS. There is nothing to install.
Yes. A file can be up to 100 MB; a larger one is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
