You can export any view that has an export symbol on the right above it to XML format. XML files can be opened with common spreadsheet tools (e.g. Excel or Numbers).
Tip: At the project level, you have the option of creating an export of all schedules and status reports of the entire project. To do this, select the desired tab (Activities or Status) by clicking on Project level and then the desired level of detail (e.g. Activity level) above the table. You can export all activities of the project or all status reports at once.
