Import Sharepoint Groups: UserId - GroupId

Hi everybody,

and thanks for the answer.

I want to share with you the solution that i find on a post.

 - I create a function with a parameter that use the GET
let
Source = (Offset) =>
let
Source =
Xml.Tables(Web.Contents("https://MYWEB.sharepoint.com/sites/MYSITE/_api/web/SiteGroups/GetById(" & Number.ToText( Offset ) & ")/Users"
)
)
in
Source
in
Source

- then i call this function with insert a new column INVOKE CUSTOM FUNCTION and using a column of the same table (the id of the groups) as parameter of the function.
- then i arrange the data to obtain what i need: extract the users id from the results.

This post help me to resolve:
