Power Query Table.UnpivotColumns Expression.Error

[AlmarBiter]

Hi Guys,

Need your help. I was encountering an error when using the Table.UnpivotColumns.

Advance Editor

I try to fix it until I came up to try simple code like this  and I encounter the same error.

let
    Source = #table({"Category", "Value1", "Value2"}, {{"A", 1, 2}, {"B", 3, 4}}),
    Unpivoted = Table.UnpivotColumns(Source, {"Value1", "Value2"}, "Attribute", "Value")
in
    Unpivoted

Appreciate your any feedback. Thank you

Hi @AlmarBiter , The error says it is a formula error: Use Table.Unpivot() or Table.UnpivotOtherColumns() as per your need. Thanks!

Hi @AlmarBiter ,

Okay, Can you replace with 'Table.UnpivotOtherColumns' instead of Table.UnpivotColumns. This function unpivots all columns except the ones specified, which might work for your case.

Could you please check and confirm? Thank you

Thanks for your help. My earlier reference included the Table.UnpivotColumns function, but after reviewing the latest Power Query documentation, it appears this function is no longer available.

There is no function named Table.UnpivotColumns. Hence, your error.

I'm now using the Table.UnpivotOtherColumns and it's working. Thanks for the help
