Why, when I export my live products out to an Excel spreadsheet, does the Long Description data in some of the product records come in as a long line of ###### marks, in stead of readable letters and numbers?
Try to click once in the upper left-hand corner of the spreadsheet (select all cells in the spreadsheet) and then double-click on the border between cell "A" and cell "B". This will auto-expand all of the cells, and the hash marks should go away.
The hash marks indicate there isn't enough "room" in the (narrow) column / cell to display the information. Doing the resize should take care of it.
