ICS to Excel

In short: Excel does not read .ics files as a table. Drop the .ics below and pick the dates. You get a CSV with one row per meeting that Excel opens, or a grid of hours per day you can paste. The plain .ics to CSV page has the column list.

ICS to Excel

.ics, .zip or Outlook CSV

An .ics file from Google Calendar, Apple Calendar or Outlook, Google's .zip of all calendars, or Outlook's calendar CSV. Several files at once are fine.

Your calendar stays on this device

The file is read and added up by this page, inside your browser. Nothing from it is uploaded. Your keyword table and rates are saved only in this browser.

No calendar export handy? or download the sample to look at it first.

The freelancer, clients and meetings in the sample are invented. It is read on this device, like your own file.

How to do it

  1. Export the calendar as .ics: from Google Calendar settings, Outlook's Save Calendar, or File, Export in Calendar on a Mac.
  2. Drop the .ics (or Google's .zip) below.
  3. Pick the dates and the time zone you want the times in.
  4. Download the detail CSV and open it in Excel, or click "Copy grid" and paste.

What it does

  • Repeating events become one row per meeting, which Excel cannot work out from the raw file.
  • Times use the time zone rules inside the file, so daylight saving does not shift rows.
  • Hours are numbers with two decimals, ready for SUM and pivot tables.
  • Several .ics files can be dropped at once and come out in one table.

Export from Google Calendar

  1. Open Google Calendar on a computer (the phone app cannot export).
  2. For every calendar at once: click the gear icon, then Settings, then Import & export, then Export. A .zip downloads. Drop the .zip here as it is.
  3. For one calendar: under My calendars, point at the calendar, click the three dots, then Settings and sharing, then Export calendar. An .ics file downloads.

Work and school accounts can have export turned off by the admin. You need the "Make changes and manage sharing" permission on a calendar to export it.

Export steps for the other apps

Export from Outlook (.ics)

  1. In classic Outlook for Windows, open the calendar, then File, then Save Calendar.
  2. Click More Options. Set Date Range to the period you bill for, and Detail to Full details. "Availability only" leaves out the titles, so no client can be matched.
  3. Save. Drop the .ics file here.

The new Outlook and Outlook on the web do not always offer this. If yours does not, use the CSV export from classic Outlook, or publish the calendar and download its .ics link.

Export from Outlook (CSV)

  1. In classic Outlook for Windows: File, Open & Export, Import/Export.
  2. Choose Export to a file, then Comma Separated Values, then your Calendar folder.
  3. Outlook asks for a date range. Pick the period you bill for. Save, then drop the .csv here.

The CSV has no time zone, no declined status and no repeat rules. Each row is one meeting as it sat in your calendar. If repeating meetings look missing, export as .ics instead.

Export from Apple Calendar

  1. Open Calendar on your Mac. If the calendar list is hidden, choose View, then Show Calendar List.
  2. Click the calendar name in the list.
  3. Choose File, then Export, then Export. Save the .ics file and drop it here.

Apple exports one calendar at a time. The "Calendar Archive" (.icbu) option is a backup format this tool does not read. Drop several .ics files at once if your work sits in more than one calendar.

Limits

  • An event counts on the day it starts, in the time zone you pick. An event that runs past midnight is not split across two days.
  • All-day events are left out unless you set hours per all-day event. Then an event over several days gives one row per day, for the days inside your date range.
  • Declined meetings are left out only when you enter your own email address, and only for .ics files. The Outlook CSV has no declined, tentative or free status, so those tick boxes do nothing for it.
  • Client keywords match whole words, so "art" does not match "Party". A keyword with @ or a dot, like @acme.com, matches inside email addresses.
  • The "events shown as free" box leaves out events marked TRANSP:TRANSPARENT in the file. That this is what Google writes for events set to Free is not confirmed against a real Google export.
  • Repeat rules by the hour or minute, by week number, or by hour of the day are not expanded. Those series are listed as not counted. Calendar apps rarely write them.
  • A repeat that lands on a time skipped by a clock change (for example 2:30 on the night clocks go forward) is skipped, as the iCalendar standard says. Some calendar apps show it an hour later instead. The page names those dates.
  • "This and all later" changes written as RANGE=THISANDFUTURE are applied to the one meeting only, with a warning.
  • The Outlook CSV must have English column names. A CSV from a German, French or other localized Outlook is refused.
  • The Outlook CSV has no time zone. Its times are read as the wall-clock times of the computer that exported them.
  • Not tested against real exports of timed, repeating and declined events from Google, Apple or Outlook. The test files are built from the iCalendar standard and the vendors' help pages. Check the first timesheet against your calendar.
  • The Toggl Track, Harvest and Clockify import files follow those vendors' help pages and were not tested by importing into a real account.

Questions

Can I just rename the .ics to .csv?
No. An .ics file is lines like DTSTART:20260302T100000, one property per line, and a repeating meeting is stored once with a rule. It needs to be read and expanded first, which this page does.
Is there an .xlsx download?
No. The downloads are CSV and tab-separated text. Excel opens the CSV, and "Copy grid" pastes into cells.
Where is the plain list of columns?
On the ICS to CSV page, linked below under Related.
Is my calendar uploaded anywhere?
No. The file is read by this page inside your browser. Nothing from it is sent to a server. You can disconnect from the internet after the page loads and it still works.
How is the client picked for each event?
From a keyword table you can edit. The first row whose keyword appears as a whole word in the event title, categories, location, or a guest's name sets the client; a keyword with @ or a dot, like @acme.com, matches inside email addresses. Suggestions come from guest email domains, categories and titles like "Acme: review". Your own domain is never suggested, and the table is filled in only once your email address is known. It is saved in your browser.
How are hours rounded?
Per event and always up: exact, to 6 minutes (0.1 hour), to 15 minutes, or to 30 minutes. With exact rounding each event counts in whole minutes and is shown as hours:minutes (0:20), and totals add the minutes before giving decimal hours, so three 20-minute calls are 1:00 = 1.00 hours. With 6, 15 or 30 minutes every row is already a whole number of hundredths, so the decimals add up.
