To Get the sites,owners,members,permission In excel Format.

Hi Chinna,

Please see if this script works for you.

$webapp = Get-SPWebApplication “your SPsite.com
$sites = $webapp | Get-SPSite -Limit All
$webs = $sites | Get-SPWeb -Limit All
foreach ($web in $webs) {
$users = $web.siteusers
write-host "Processing " $web.url -foregroundcolor cyan
write-host "Site Admins:" -foregroundcolor yellow
foreach ($user in $users) {
if ($user.IsSiteAdmin) {
write-host $user.Name
}
#write-host $user.Name "IstSiteAdmin: " $user.isSiteAdmin
}
Write-host "Site Owners" -foregroundcolor green
foreach ($user in $users) {
if ($web.DoesUserHavePermissions($user,[Microsoft.SharePoint.SPBasePermissions]::FullMask)) {
write-host $user.Name
}
}
}

Please let me know if that works
