Power Query function Number.From returns incorrect value

Number.From("200+") gives a result of 200 rather than throw an error

Hi @QiongJoanZ 

You can use this to check for Text - the full query is in this PBIX file

 

if Value.Is([Col1], type text) then 1 else 0)

in the case where data source is csv file and all vales are read as text, this solution won't work. 

I am happy with your solution for my purpose. But that fuction still gives wrong result.

What I wanted is to test if each cell in a table is text or not. This gives me wrong result

Hi @QiongJoanZ 

So you want it to throw an error?  What do you actually want it to do in this instance? You could check the text value for the + and then not do the conversion to number, like this

if Text.Contains([Column1],"+") then [Column1] else Number.From([Column1]))
