With arrays you can do it : 


      Count | Entry |   Description   
     -------|-------|----------------- 
          2 | Foo   | yada yada       
          3 | Bar   | blah blah blah  

Using this with "**Count**" in `A1`; "**Description**" in `C1`; etc..

    ={B1:C1; transpose(ArrayFormula(SPLIT(transpose(ArrayFormula((REPT(B2:C2&",",A2)))),",",true,true)));transpose(ArrayFormula(SPLIT(transpose(ArrayFormula((REPT(B3:C3&",",A3)))),",",true,true)))}

Result : 

      Entry |   Description   
     -------|----------------- 
       Foo  | yada yada  
       Foo  | yada yada 
       Bar  | blah blah blah
       Bar  | blah blah blah
       Bar  | blah blah blah  


[Working example in `A5`][1]

Edit : New solution using column 

        =transpose(split(TEXTJOIN(",",true,transpose(ArrayFormula(REPT(B2:B100&",",$A2:$A100)))),",",true,true))

Now to use it you juste have to expand it on every column. Don't forget to modify the range I used (`B2:B100` and `$A2:$A100`)
