Sharepoint List - Documenting Changes in Field Values

Csalinas144 I know what REST URL you can use, that would give you the URL for each previous versions of the same file but I got stuck

To elaborate, if your sharepoint details are following

site_url = xyz.com/teams/Analytics
Folder Name = /teams/Analytics/Shared%20Documents/DataMaster
file_name =test.xlsx

You can start with a REST URL like following and wrap that in Xml.Tables(Web.Contents())

https://xyz.sharepoint.com/teams/Analytics/_api/web/GetFolderByServerRelativeUrl('/teams/Analytics/Shared%20Documents/DataMaster')/Files('test.xlsx')/versions?select=Url

let
    Source = Xml.Tables(Web.Contents("https://xyz.sharepoint.com/teams/Analytics/_api/web/GetFolderByServerRelativeUrl('/teams/Analytics/Shared%20Documents/DataMaster')/Files('test.xlsx')/versions?select=Url")),
    entry = Source{0}[entry],
    #"Added Custom" = Table.AddColumn(entry, "Custom", each let x =[content],
    y = x{0}[#"http://schemas.microsoft.com/ado/2007/08/dataservices/metadata"]{0}[properties]{0}[#"http://schemas.microsoft.com/ado/2007/08/dataservices"]{0}[Url]
    in "https://xyz.sharepoint.com/teams/Analytics"&y)
in
    #"Added Custom"

It will bring you here

Invoking Web.Contents on each of these URL does not return the excel and returns an error [Error Text -Specified value has invalid CRLF characters] while the same URL in browser returns that corresponding version of excel

There is a previous question on this  https://community.powerbi.com/t5/Desktop/Importing-previous-versions-of-Sharepoint-Files-into-PowerB...

and maybe omeallynile can shed some light on how to resolve that.
