can do this using notepad++ and regex

example - retrieve only keys containing 'value':

"appRoles": [

{

"allowedMemberTypes": [

"Application"

],

"description": "Allows the app to read access reviews, reviewers, decisions and settings in the organization, without a signed-in user.",

"displayName": "Read all access reviews",

"id": "d07a8cc0-3d51-4b77-b3b0-32704d1f69fa",

"isEnabled": true,

"origin": "Application",

"value": "AccessReview.Read.All"

},

{

in notepad do search>select regex>

enter this regex:

"value"[ :]+((?=\[)\[[]]*\]|(?=\{)\{[\}]*\}|\"["]*\")

and replace with empty

(example of an OR search:

("value"[ :]+((?=\[)\[[]]*\]|(?=\{)\{[\}]*\}|\"["]*\"))|("id"[ :]+((?=\[)\[[]]*\]|(?=\{)\{[\}]*\}|\"["]*\"))
