Are you applying the filters to the first sheet on the dashboard too? If no, please ensure that they are applied on them also by right-clicking on the filter and applying it to the first sheet too.
Try checking out the new Extensions Gallery which you can incorporate into your Dashboard. This link is for Information Lab extension for exporting data and the ability to set which columns get exported if used by user:
Hope it helps! Thx, Don
Thanks for the replies all!
Yes the sheet that is downloaded has the filters applied to it. But when you add .csv to the end of a tableau hyperlink it downloads the file as it was when first opened (ie, no filters applied).
Regarding the extension, I gave it a shot! But it said that it required some form of authentication to the Extension source to operate, of which my work network will not connect to it?
