Passing literal string to a collection

Hi guys,

 

I spent a lot of time looking into how I can save a table into a single record on a SharePoint list (not patch the table to the list) and nearly pulled my hair out looking for an answer. My goal was to have a feature to show a single record in my canvas app with a collection showing the table stored in a record cell next to it. 

 

I've decided I will go with JSON to do that. To my tremendous frustration, I've discovered that you can easily save a collection as JSON, but you can't convert it back to a collection. I don't want to use flow, so I wrote a parser to convert JSON string into a string that can be passed to Collect() function.

 

Now, the problem is when I pass my variable to a Collect() function, it takes it as one item, instead of a correct syntax for collection. Can I somehow pass it as a literal string?

 

I'm attaching screenshots to show what I have in mind.

Hi guys, nevermind 😉

It appears PowerApps doesn't support eval feature. There's an idea posted to introduce it in the future, so if you'd like it to become true, please vote (I did 😉 ).
