Isref Function Examples

The following spreadsheet shows examples of the Excel Isref function:

 Formulas:
  A B
1 =ISREF( B1 )  
2 =ISREF( B1:B2 )  
3 =ISREF( B1:D4 C1:C5 )  
4 =ISREF( "text" )  
5 =ISREF( B1 * B2 )  
 Results:
  A B
1 TRUE  
2 TRUE  
3 TRUE  
4 FALSE  
5 FALSE  

Note that, in cell A5, the expression B1 * B2 returns a value (the product of the values in two cells), and so in this case, the Isref function returns FALSE.
