Delete sharepoint files older than 60 day using Rest api from powershell

A caml query will be enough to make the script delete files in a specific folder according to date.

$site = new-object Microsoft.SharePoint.SPSite("site url") 
$web = $site.rootweb 
$list = $web.Lists["library name"]

$query=new-object Microsoft.SharePoint.SPQuery 
$caml='<Where>
        <Leq>
            <FieldRef Name="Created" />
            <Value IncludeTimeValue="TRUE" Type="DateTime">2020-02-20</Value>
        </Leq>
    </Where>'

$query.Query=$caml | Write-Output
$query.Folder = $list.RootFolder.SubFolders["folder name"];
write-host $query
$items=$list.GetItems($query) 
write-host $items.Name
$folderItemsTotal = $items.Count;
for($x=$folderItemsTotal-1;$x -ge 0; $x--)
{
        $items[$x].Delete()
}
$web.Dispose() 
$site.Dispose()

I think you can use the below script for your need, this will take fromDate and ToDate as a parameters which will scan through all documents within that range of dates and delete all files from those date. For your scenario you can give the FromDate as 60 days back and ToDate as current date.

This script has been developed in PowerShell CSOM object model, so this will fit both in SharePoint online and SharePoint on-premise.
