Excel displays error messages such as #DIV/0!, #NAME?, #VALUE!, and #REF! when formulas cannot be calculated properly. Each error points to a different kind of problem, such as dividing by zero or using an invalid cell reference.
Learning what common errors mean helps users troubleshoot spreadsheets more effectively and avoid frustration when formulas do not behave as expected.
