Checks whether a value is a number. Learn more
ISNUMBER is a function in Google Sheets that checks whether a value is a number or not. It returns a Boolean value of TRUE if the value is a number and FALSE if it is not. This function can be useful when you are working with a dataset that contains different types of data and you want to identify which values are numeric.
For example, if you have a column of data that contains both numeric values and text values, you can use the ISNUMBER function to create a new column that only contains TRUE or FALSE values indicating whether each cell in the original column is a number or not. You can then use this new column to filter or sort the data based on numeric or non-numeric values.
