[Excel] Expressions that yield variant data-type cannot be used to define calculated columns.

[markus_zhang]

Hi experts,

I'm getting this strange error in Excel Power Pivot:

Expressions that yield variant data-type cannot be used to define calculated columns.

Now if I look at the columns that have this error, the formula is simple:

IFERROR([NTK], 0)

However in my case [NTK] column is all empty, and when I check the imported data all columns have "General" type but only NTK has this problem. Other columns have empty cells too so I don't think that's the problem.

I really have no idea what to do about this weird thing, but alas I cannot upload my Excel file, and a dummy file probably won't work out.

Hi @markus_zhang,

This error prompts when there existing two different data types in formula. In your scenario, you used both number value (zero 0 ) and text value ( [NTK] ) in  single column.

You can replace the 0 with BLANK() or "" to avoid such an error.

Hi I figured it out,

=[NTK] works but =IFERROR([NTK], 0) doesn't work, weird...
