Excel formating in email attachment without using XML.

Hello Eperts,

I have a requirement where in I am sending an excel as an attachment, now the requirement is to format this excel.

Scenario: An email is to be sent with attached excel, the column headings should be in BOLD,  the columns should be emphasized/optimized,

               few of the columns are to be colored and so on...

Please do suggest an approach to ahcieve this, I am using below code...

TRY.
      cl_bcs_convert=>string_to_solix(
        EXPORTING
          iv_string   = lv_string
          iv_codepage = '4103'  "suitable for MS Excel, leave empty
          iv_add_bom  = 'X'     "for other doc types
        IMPORTING
          et_solix  = binary_content
          ev_size   = size ).
    CATCH cx_bcs.
      MESSAGE e445(so).
  ENDTRY.

*     add the spread sheet as attachment to document object
  TRY.
      go_email_body->add_attachment(
           i_attachment_type    = 'xls'                     "#EC NOTEXT
           i_attachment_subject = 'Process' "#EC NOTEXT
           i_attachment_size    = size
           i_att_content_hex    = binary_content ).
    CATCH cx_document_bcs.
      MESSAGE e898(so).
  ENDTRY.

I have tried to achieve it using FM: SO_NEW_DOCUMENT_ATT_SEND_API1

Note: Please don't provide links which are saying XML to excel conversion, there is an issue with this.

Warm Regards,
