From the O365 Amin it is possible to produce and export an audit log of all Power BI activities. The file produced is CSV and one of the columns is filled with JSON data.
Example:
2018-02-09T17:40:44.0000000Z,abcdefg@xyz.com,InstallApp,"{""RecordType"":20,""CreationTime"":""2018-02-09T17:40:44"",""Operation"":""InstallApp"",""UserType"":0,""Workload"":""PowerBI"",""UserId"":""abcdefg@xyz.com"",""UserAgent"":""Mozilla\/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit\/537.36 (KHTML"",""Activity"":""InstallApp""}"
How can I use Power Query to parse the JSON within the CSV and create/populate columns from the JSON?
