Parsing Date with JSON

[SylvieLet17]

Hi all, 

I don't have much experience with JSON, but I'm trying to decipher and use a date value from the "Shared with details" column in a SharePoint library in a Flow. The column data ends up looking like this:

{"i:0#.f|membership|firstname.lastname@domain.org":{"DateTime":"/Date(1557740213028)/","LoginName":"person.who.shared@domain.org"}}

And I've managed to extract the date in a compose action, but now I guess I need to use JSON to translate this to a usable date value. A user said I could use this formula: 

var d = new Date();
d.setTime(1557740213028);

but I have no idea how to plop that into a Parse JSON action. Help?

Is your example a valid JSON format? If so you can use "Pasrse JSON" action block currently supported in Microsoft Flow

Here you will find an excellent tutorial via @sergeluca
