Export Your Asana Calendar to Google Sheets

Two different "calendar" features

Asana has two things that answer to "calendar," and they don't do the same job. Sync to Calendar is a one-way subscription feed: tasks with due dates show up as all-day events in Apple Calendar, Outlook, or Google Calendar. It syncs to a calendar app, not a spreadsheet, and updates in your calendar never write back to Asana.

The Calendar view inside a project is different. It's one of several ways to look at the same project, alongside List, Board, and Timeline. Switching to Calendar view changes how tasks are displayed, not what data the project holds. Exporting a board works the same way for Board view.

What actually exports to Sheets

Export or sync to Google Sheets is a project-level action, triggered from the project's dropdown menu regardless of which view you're looking at. Choose Export or sync → Google Sheets. What comes out is the project's task data: due dates, assignees, sections, custom fields, not a rendering of the calendar grid itself. Being in Calendar view when you export doesn't add or remove anything from that data.

This is the same feature and the same limits as any other Asana-to-Sheets export: gated to Advanced and Enterprise plans, one-way, and capped at 500 rows per sheet. See does Asana have a Google Sheets integration for the full picture of what that native export does and doesn't do, and exactly how that 500-row cap behaves when a project has more tasks than that.

Date formatting, timezones, and tasks without a due date

Asana's API returns dates in ISO 8601 (2026-09-04 for a due date with no time, or a full timestamp for one with a time component). Written straight into a cell as text, that string sorts and filters like a word, not a date, so it needs converting to a real spreadsheet date value before pivots or WEEKNUM/EOMONTH formulas will work on it. A task with only a due date and no due time carries no timezone information at all, so treat it as a calendar date rather than a specific instant. A task with a due time, and one with no due date set, both need explicit handling: the first should keep its time component if the report cares about time of day, and the second should land as a genuinely blank cell rather than a zero date that would otherwise sort to the top of every date-based view.

Worked example: a two-week content calendar

With Due date as a real date type, =WEEKNUM([due date]) groups the three tasks into calendar weeks without a helper column, and a standard Sheets filter view for "next 7 days" works against today's date directly.

Troubleshooting

Dates look right in Asana but sort wrong in the sheet

That's the ISO-string-as-text problem: the column is holding text that happens to look like a date, not an actual date value. Reformat the column as a date type, or re-run the export through a path that writes dates natively.

A task with no due date shows a date anyway

Check whether the export logic defaulted a missing date to an epoch value like 1899-12-30 or 1970-01-01 instead of leaving the cell empty; that's a common side effect of coercing a blank API field into a spreadsheet date type carelessly.

If the report is really about due dates

A calendar-framed report usually wants one thing: tasks with due dates in a given range, readable as spreadsheet dates rather than calendar events. That means keeping the due-date column as an actual date type, not text, so filtering and pivoting by week or month works without a conversion step.
