Table.ReplaceValue

Hello Experts, 

 

I'm trying to replace values - to blank or null in a columns using:

= Table.ReplaceValue(#"Renamed ColumnsY",Number.FromText("-"), null,Replacer.ReplaceValue,{"ColumnX"}) 

 

However I get the following error: 
DataFormat.Error: We couldn't convert to Number.
Details:
-

 

Is there an easy wayt to overcome this? 

 

Thanks in advance!

Don't use Number.FromText("-"). Since you are trying to replace "-" with null, hence Number.FromText is not needed. This will give error as "-" can't be identified as number.

Use below

= Table.ReplaceValue(#"Renamed ColumnsY","-",null,Replacer.ReplaceValue,{"ColumnX"})

Yes, and then I could use Replace Errors instead. Thanks!
