Get visual metadata with PowerShell or REST API

[Krcmajster]

I don't know if this is the right place to ask this. 
I want to automate some things for our team. I started to play with PowerShell and I wanted to use it to do what I have planned. 
I want to get visual metadata like name, fields or measures used, description, etc. But from what I see Power BI cmdlets (and REST API) don't go further from Power BI report (actually tile, but we do not have those). 
Does anyone know how I can pull this via script, it does not need to be PowerShell, JS or Pyhton are also acceptable.

Short answer : You can't, this meta data is not exposed.

Long answer:  If you have access to the PBIX file you can extract the meta data from there. PBIX files are archives and you can view them with your favorite viewer or extract them with Powershell.

Hi , I have a similar Requirement to get XML of the reports/dashboards. I tried to convert pbix files to pbit and then zip and then extract. but I didnt get the XML file from anywhere which gives me the Report details. Any suggestions here ?

Also JSON file will also work if MS has exposed this.

Wait for the TMDL implementation. Download the June 2023 Power BI Desktop, save as .PBIP - into a git repository
