Is someone aware of an equivalent function in PowerApps that will, just like the Excel Eval() function, take an input string value, execute commands specified within it, and produce a result? For example, if I have I have two variables, varOne already set to the value 1 and a variable x set to 8, and then I fed this Eval() function the following string:
"x + " & varOne & " = " & x + varOne
...it would produce:
"x + 1 = 9"
Does something like this (or a reasonable workaround) exist for PowerApps?
No, this functionality does not exist in PowerApps at this moment. Feel free to create a new feature request in the PowerApps Ideas board for this.
