The ASR module has been great and inspired other modules. You may find that Sitecore PowerShell Extensions is an excellent alternative since it allows you to virtually script any report you need.
Check out the documentation here.
Example: The following determines all the fields that belong to the item, excluding the Standard Fields. The final report can be exported from the top ribbon.
# Create a list of field names on the Standard Template. This will help us filter out extraneous fields.
$standardTemplate = Get-Item -Path "master:" -ID "{1930BBEB-7805-471A-A3BE-4858AC7CF696}"
$standardTemplateTemplateItem = [Sitecore.Data.Items.TemplateItem]$standardTemplate
$standardFields = $standardTemplateTemplateItem.OwnFields + $standardTemplateTemplateItem.Fields | Select-Object -ExpandProperty key -Unique
# Change the Id to something other than the Sample Item template.
$itemTemplate = Get-Item -Path "master:" -ID "{76036F5E-CBCE-46D1-AF0A-4143F9B557AA}"
$itemTemplateTemplateItem = [Sitecore.Data.Items.TemplateItem]$itemTemplate
$itemTemplateFields = $itemTemplateTemplateItem.OwnFields + $itemTemplateTemplateItem.Fields | Select-Object -ExpandProperty key -Unique
$filterFields = $itemTemplateFields | Where-Object { $standardFields -notcontains $_ } | Sort-Object
$path = "master:{110D559F-DEA5-42EA-9C1C-8A5DF7E70EF9}"
@(Get-Item -Path $path) + @(Get-ChildItem -Path $path -Recurse) | Show-ListView -prop $filterfields
