Analysing HTTP page

Dear Forum members,
I am looking for guidance to analyse webpage content. The content is for example

{"POWER":"ON"}

and I need to find the values POWER and ON.

Any guidance heavily welcome

Read the forum guidelines for some advice on how to ask a good question. You have not provided sufficient information.

“Any guidance heavily welcome”

Have you looked at the web page source?

You could start with this Google search:
arduino parse http get request

This was the search word I was missing. Thanks for your help!

ArduinoJSON comes to mind.
