Hi @Veera_Raj

I think this link should help you.

use try catch,

in exception handler, if the value is null, use assign activity to replace null with anything.

i want yo replace null value in array with “N”, not in exception

i have array like {“xxxxx”,“”,“y”,“”,“y”}.want to replace Null with “N”
expected output is {“xxxxx”,“n”,“y”,“n”,“y”}

Hi @Veera_Raj

Try with this Expression

Dt.AsEnumerable().Select(Function(row) row(“Column Name”).ToString.Replace(“”,“N”)).ToArray

You can replace it like this

this is for only specified column , can we make into dynamic ? means all column and row

Hi @Veera_Raj

For an array you can try as below

arr_usernames.Select(Function(x) x.Replace(" ", “N”)).ToArray()

how to pass the array index?

this logic not giving result

You can pass it in properties of for each loop activity as output index of for each loop.

Hi @Veera_Raj

Use the expression below!

Assign LHS =arrayVar

RHS= arrayList.Select(Function (e) If(isNothing(e) OrElse String.IsNullOrEmpty(e.toString), “yourReplace Value”, e)).toArray

Refer to the screenshots below!
