ExamplesHere are a few example use cases that explain how to use the
ISNAformula in Google Sheets.
Checking for #N/A errors
ISNA function can be used to check if a cell contains the #N/A error. This can be helpful when working with large datasets or complex formulas that may return errors.
ISNA function can be used in combination with conditional formatting to highlight cells that contain #N/A errors. This can make it easier to identify and correct errors in a spreadsheet.
ISNA function can be used in combination with other functions to handle errors in a formula. For example, if a VLOOKUP function returns #N/A, you can use the
IF function with
ISNA to display a custom error message.
ISNAnot working? Here are some common mistakes people make when using the
ISNAGoogle Sheets Formula:
Not providing a value as input
The ISNA formula requires a value as input to determine whether it is #N/A or not. Make sure to provide a value as input.
Using the formula with non-numeric values
The ISNA formula only works with numeric values. If you try to use it with non-numeric values, it will return the #VALUE! error. Make sure to use it only with numeric values.
Not using parentheses around the input value
The ISNA formula requires the input value to be enclosed in parentheses. If you forget to do this, it will return the #NAME? error. Make sure to enclose the input value in parentheses.
The following functions are similar to
ISNA or are often used with it in a formula:
ISERRORformula is used to check if a value contains an error. This formula returns
TRUEif the value is an error, and
FALSEif it is not. This function is most commonly used in combination with other formulas that can return errors, to ensure that the resulting value is valid.
IFERRORformula is used to check whether a specified value results in an error or not. If the value results in an error, then it returns a user-specified value instead of the error. This function is commonly used to prevent errors from breaking a formula or to replace error messages with custom messages.
VLOOKUPfunction is a lookup formula used to search for a value in the first column of a range of cells (the search key) and return a value in the same row from a specified column in that range. This function is most commonly used to look up and retrieve data from a table.
HLOOKUPfunction is a lookup formula that searches for a key in the top row of a table and returns the value in the same column for a specified row. This function is commonly used to extract data from a table based on a specific criteria.
