Syntax

IFERROR(value, [value_if_error])

  • value - The value to return if value itself is not an error.

  • value_if_error - [ OPTIONAL - blank by default ] - The value the function returns if value is an error.

Notes

  • IFERROR(exp1,exp2) is logically equivalent to IF(NOT(ISERROR(exp1)),exp1,exp2). Ensure that this is the desired behavior.
