A good understanding of file types in Tableau can save you a ton of time. I've covered the key types and as new file types become available, I'll be updating this playlist.
Tableau Bookmarks allow you to save a single sheet for re-use in other workbooks. It works exactly the same way as copying a tab from one workbook to another but instead, it persists as a file and can be shared across a team. Tableau release notes: "You can save a single worksheet as a Tableau bookmark. When you save the bookmark, Tableau creates a snapshot of the worksheet. Bookmarks can be accessed from any workbook using the Bookmarks menu. When you open a bookmarked worksheet, it adds the worksheet to your workbook in the state that it was in when it was bookmarked. It will never update or change automatically. Bookmarks are convenient when you have worksheets that you use frequently."
