Microsoft Flow - Expressions and how to use them

In this post I'm looking at the coding part of the low-coding solution that Microsoft Flow is. 

 

For every Action, or condition or switch you can use expressions. Expressions are coparable to functions, procedures or methods in traditionalprogramming languagas.

When you initially look at expressions you will find that Mcirosoft Flow offers you about 30 expressions and you migth be quite disappointed. Don't be!

 

When you look a bit further and you start typing oin the search box ( just after the fx) then you will find out that there is more. A lot more!

Ok, in this post I could go through all of them, but I'm not going to do that. ?I would probably only bore you to death anyway!

 

So just by typing ahead I found fucntions like substring.

Then when you coplete the word substring after the first bracket Microsoft Flow offers you a syntax and a description of the Expression.

Can things get any easier?

 

you can even build some logic in using an if expression.

And if you are still not happy. There is more! You can even use Dynamic content in your expressions.

Do you have any dificulties using Expressions? Or do you need some help then please leave a comment below or  post your question on the Microsoft Flow Community Boards

Are there any good guides to learn expressions and low coding? The web builder in PowerAutomate is ok but you need to know about formulas and stuff before using it.
