    Tableau Prep: error occurred while communicating with Microsoft Excel Reader

    Kevin Cash

      I'm new to Tableau Prep, but have used Tableau in my MBA program and in some work over the last couple years.


      I'm trying to merge some data from two different Excel files.  The first one is about 760 rows and it loads just fine.  This one, however, is about 43k lines and will not load (see image below).  I keep getting the error in the image that says Prep is unable to read it.  Is the file size too large (3.8MB)? I already tried renaming it and loading it again (as suggested in the error), but there was no change.  Please help!
