Hi Vijay,
Thanks for writing to us
if you want to extract only the name then you can substring like below
"@substring(triggerBody()?['Filename'],0,indexOf(triggerBody()?['Filename'],'.'))"
if you want to extract after the . Then it will be like
"@substring(triggerBody()?['Filename'],indexOf(triggerBody()?['Filename'],'.'))"
