Cannot convert a negative text to decimal

Hi,

 

I am new to power bi. I have a column which have decimal values. But, the datatype is text. When I tried to convert the datatype to decimal power-bi query editors throws below error.

 

DataFormat.Error: We couldn't convert to Number.
Details:
−0.38

 

(note: It happens to only negative numbers)

 

Please help

I have a feeling that that "−" character isn't same as "-". As you can see, it's a bit wider. Did you get from Web.Page? Maybe you can do "Right click on columns > Replace Values" and replace "−"s with "-"s.

@baiju,

As I tested, PowerBI can certainly convert the text "negative numbers" into a negative number, so there's something else going on here.

I import the data into Power BI as following screenshot.

Please check the negative sign in the string if there is actually some kind of Unicode character, or that there's something which looks like a digit in the text but is actually a letter? Would you be able to share your data with us for further analysis?

Thanks Angelia & Arify,

 

The issue is with  "−" charactor. I replaced it with "-" . Now Everything works fine
