split or extract string from string

[AdhamFH]

if i have a string like this ["test@test1.com"] how to get the value only test@test1.com?

Use the following.  The substring starts after the second character (removing the [") and the Length-4 stops before the final two characters (removing the "])

substring(variables('target String'),2,sub(length(variables('target String')),4))

Hello @AdhamFH ,

the string has format of an array with a single object, so you could also store it into an array variable and then get the first object (on index 0) from that array. Or use 'Apply to each' if you expect there might be multiple strings, e.g. ["test@test1.com","test2@test1.com"...].

@tom_riha you don't even need to put it into an array variable. So you could just use an expression like:

first(outputs('string'))

Even without being in a array variable it will still get interpreted as an array.

thank you for the tip, that seems to be the optimal solution. 🙂
