But getting out of index error.

    Hi,
     
    One way to do this is to find the position of the label "Case Number" then add 11 to it and extract the next 5 characters, shown below.  Remember this is 0-based use adjust the "12" number of characters to match the actual format in your text.
     
    substring(body('Get_file_content'), add(indexOf(body('Get_file_content'), 'CaseNumber:'), 12), 5)
