data flow date format

Question

Hello,
I would like to format the column values in GB date format as follows but I get null.
Any suggestions?
note that the existing values (SourceFormat) are as in yyyy-MM-dd but I would like to change them to: dd/MM/yyyy

I use the following in the expression builder
toDate(toString(byName($0)),Config#lookup($0).SourceFormat, 'Europe/London')

Hello @arkiboys ,
Thanks for the ask and using Microsoft Q&A platform .

I did try to play with the toDate function and though i was not successful , I know why its showing NULL in your case . Its expects a the input format as a parameter , which you are not passing . please read here

Quick snippet from the doc

toDate
toDate(<string> : any, [<date format> : string]) => date

Converts input date string to date using an optional input date format.

I will try to get in touch internally with the SME’s , but now you can try the below work around .

concat(split(SourceFormat,'-')3,'/',split(SourceFormat,'-')2,'/',split(SourceFormat,'-')1)

Please do let me know how it goes .
Thanks
Himanshu
