# ISNOTBLANK function

## ​​​Description

Returns TRUE if the given Value is defined, otherwise it returns FALSE.

> [!TIP]
> For improved performance, we recommend that you use the [ISDEFINED function](/v1/docs/isdefined-function) if possible.
> 
> - `ISNOTBLANK` Returns TRUE or FALSE. This function populates all cells of the property or Metric. The result is 100% density, and can impact performance.
> - `ISDEFINED` Returns TRUE or BLANK. Any cells that are equal to FALSE remain unpopulated. The result is sparse, which means less data and less time required to write the result in the database. This prevents max cardinality and timeout errors.
