How Do I Use the Fill Null Function in Excel?
The Fill Null function within our Excel Add-In allows you to override an empty or missing data point by specifying exactly what should appear in that cell instead. This is particularly useful when you encounter the error message 'ERR: NO DATA', as it enables you to replace that error with a more polished, client-ready value such as a zero, “N/A,” or a custom label that aligns with your reporting standards.

I'm still seeing an error message after I updated the formula, what am I doing wrong?
- Check and make sure that you added quotes around the fill null input, without the quotes the error message will not go away.
