Windows logon failures with the failure reason and logon type decoded

Windows logon failures parsed from event logs. This query is based on the information in this article: 

select datetime,

  json_extract(,'$.EventData.TargetUserSid') as 'sid',
  json_extract(,'$.EventData.TargetUserName') as 'username',
  json_extract(,'$.EventData.Status') as 'failure_reason',
  case json_extract(,'$.EventData.Status')
    when lower('0xC0000064') then 'user name does not exist'
    when lower('0xC000006A') then 'user name is correct but the password is wrong'
    when lower('0xC0000234') then 'user is currently locked out'
    when lower('0xC0000072') then 'account is currently disabled'
    when lower('0xC000006D') then 'reason not specified'
    when lower('0xC000006F') then 'user tried to logon outside his day of week or time of day restrictions'
    when lower('0xC0000070') then 'workstation restriction'
    when lower('0xC0000193') then 'account expiration'
    when lower('0xC0000071') then 'expired password'
    when lower('0xC0000133') then 'clocks between DC and other computer too far out of sync'
    when lower('0xC0000224') then 'user is required to change password at next logon'
    when lower('0xC0000225') then 'evidently a bug in Windows and not a risk'
  end 'failure_status_description',
  json_extract(,'$.EventData.LogonType') as 'logon_type',
  case json_extract(,'$.EventData.LogonType')
    when '2' then 'INTERACTIVE'
