If you want to upload an EXCEL file. you can achive it by first saving excel as
tab delimeted text file. This is simple open excel from save as choose
save as type Text( Tab delimeted).txt.
Now use file upload UI element from webdynpro abap. within the context declare
a context node lets call it NODE  with attribute File type XSTRING.  Bind
the data property of file upload UI element to the attribute 'File'.
Create a button upload and on its action write the following code.
Data: s_cont type string,
        x_cont type xstring,
        convt type ref to cl_abap_conv_in_ce,
        item_file type xstringval.
  data: input_string type string,
        fields  type string_table,
        fields2  type string_table,
        tbl_fields  type string_table,
        s_table type string_table,
        ls_table like line of s_table,
        ls like line of fields,
        lv_kunnr type kunnr,
        lv_ret type boolean,
        lv_num_cols type i.
   field-symbols: <wa_table> like line of s_table.
    DATA:
      node_file                           TYPE REF TO if_wd_context_node,
      elem_file                           TYPE REF TO if_wd_context_element,
      stru_file                           TYPE if_v_upload=>element_file ,
      item_file                           LIKE stru_file-file.
*   navigate from <CONTEXT> to <NODE> via lead selection
    node_file = wd_context->get_child_node( name = if_v_upload=>wdctx_node ).
*   get element via lead selection
    elem_file = node_file->get_element(  ).
*   get single attribute
    elem_file->get_attribute(
      EXPORTING
        name =  `FILE`
      IMPORTING
        value = item_file ).
  convt = cl_abap_conv_in_ce=>create( input = item_file ).
  convt->read( importing data = s_cont ).
  "Column headers
  split s_cont at cl_abap_char_utilities=>cr_lf into table s_table.
  read table s_table into ls_table index 1.
  " delete column header
  delete s_table index 1.
  loop at s_table assigning <wa_table>.
      split <wa_table> at cl_abap_char_utilities=>horizontal_tab into : ls_data-recordid
                                                                        ls_data-candno
                                                                        ls_data-fname
                                                                        ls_data-inits
                                                                        ls_data-lname
                                                                        ls_data-gesch
                                                                        ls_data-gbdat
                                                                        ls_data-uln.
        append ls_data to lt_data.
      clear ls_data.
    endloop.
  wd_this->m_node_data->bind_table(
     exporting
        new_items            = lt_data
        set_initial_elements = abap_true ).
endmethod.
