If I have already imported a project from an excel spreadsheet via CSV with a couple hundred tasks in it, inclusive of associated due dates, assignees, etc. and now something in the project changed that is forcing me to update all the due dates, can I import another CSV with only the updated due dates?
Hi @MVanGessel and welcome to the forum.
Unfortunately no - the CSV import only imports new projects. There was a recent discussion of your question here and no one came up with a solution for updating existing tasks based on a re-import, short of writing some custom code using the Asana API. See here for more:
