Is there a way to export the Online site (SharePoint Online) like one done in Onpermises using a power shell script "Export-SpWeb "http://AAAAA:28769/sites/TargetSite" -ItemUrl "/sites/TargetSite/GA folder" -NoFileCompression -Path "E:\Temp" "
which export all the xmls for the particular site ?
Or is there any alternative to view those xmls including manifest.xml using any tools or something like that ??
Use the OfficeDevPnP.PowerShell commands from the PnP provisioning framework to extract and reuse site templates for SharePoint Online and Office 365.
Here is a starting summary description on MSDN of the PnP remote provisioning resources on GitHub.
Example:
Connect-SPOnline [mySourceUrl]
Get-SPOProvisioningTemplate -Out demo.xml
Connect-SPOnline [myDestinationUrl]
Apply-SPOProvisioningTemplate -Path .\demo.xml
