The common error types you may encounter in Google Sheets, particularly in formulas, include the following: 

  • #N/A (Not Applicable): Occurs when a value is not available to a function or formula, such as when a lookup function cannot find a match.
  • #DIV/0! (Division by Zero): Appears when a number is divided by zero, or a formula refers to a cell that is zero or empty in the denominator.
  • #VALUE! (Value Error): Indicates that a wrong type of argument or operand is used in a formula, or if an operation is not supported (e.g., trying to perform a mathematical operation on text).
  • #REF! (Reference Error): Shows up when a formula refers to an invalid cell or range, often because the referenced cells were deleted or moved.
  • #NAME? (Name Error): Displays when Google Sheets doesn’t recognize the text in a formula, commonly due to a misspelled function name or range name.
  • #NUM!  (Number Error): Occurs when a formula contains invalid numeric values, such as a negative number for a function that expects a positive value.
  • #NULL! (Null Error): Happens when specifying an intersection of two ranges that do not actually intersect.
  • #ERROR! (General Error): A general error message for other unspecified problems with a formula or syntax that Google Sheets cannot parse.
  • #### (Column Too Narrow): Not a formula error in the same sense, but an display issue indicating the column is too narrow to display the full content.
  • Circular Reference (Warning): A warning that appears when a formula refers back to its own cell, either directly or indirectly. 

The common error types you may encounter in Microsoft Excel, particularly in formulas, include the following: 

  • #N/A (Not Available): The formula cannot find the referenced data (common in VLOOKUPMATCH).
  • #DIV/0! (Division by Zero): Occurs when a formula divides by zero or an empty cell.
  • #NAME? (Name Error): Excel does not recognize text in a formula, usually due to a misspelled function or undefined range name.
  • #NULL! (Null Error): Occurs when specifying an intersection of two areas that do not actually intersect.
  • #NUM! (Number Error): A formula contains invalid numeric values, or a calculation produces a result too large/small to be displayed.
  • #REF! (Reference Error): A cell reference is invalid, often caused by deleting cells or sheets referred to by a formula.
  • #VALUE! (Value Error): The wrong type of argument is used in a function (e.g., text in a formula expecting a number).
  • #SPILL! (Spill Error): A dynamic array formula tries to output multiple values, but the destination range is not empty.
  • #CALC! (Calculation Error): A formula or function has a calculation error (common with advanced array formulas).
  • #BLOCKED! (Blocked Error): Occurs when a formula is blocked by security settings.
  • ###### (Display Error): The column is not wide enough to display the value, or the cell contains a negative date/time.
  • #GETTING_DATA: The formula is waiting for a slow data source (common with external data connections).
