You want to inspect only the unfinished tasks in a shared Google Sheet while a colleague reads the whole list. An ordinary filter and a filter view serve different collaboration needs. A filter view applies filtering to your own view; it does not make the other rows secret.
Choose a view before filtering
In Google Sheets on a computer, open Data → Create filter view. Check that the range includes the intended table and its headings, then filter the status column. With permission to save views, give it a clear name such as “My unfinished review” and use the displayed Save View/Save controls. Reopen the named view to verify the rule rather than assuming it was retained.
Google allows a viewer without edit access to create a temporary filter view, but that view is not saved. Check your permission before planning to reuse or share a named view. A link to a view also does not grant access to the spreadsheet itself.
Verify rows and return to the full list
For a harmless three-row example with statuses Done, Open, Open, the Open view should show two data rows. Close the view and check that all three records remain. Do not replace hidden values with blanks or delete rows merely to reproduce the view. Filtering changes what you inspect, while editing cell contents still changes the shared file.
