Unwanted Character in excel download

Hi Experts,

I am facing one issue. I am using FM EXCEL_OLE_STANDARD_DAT to download excel.

   call function 'EXCEL_OLE_STANDARD_DAT'
    exporting
      file_name                 = lv_filepath          "file path
    tables
      data_tab                  = gi_sheet_row
      fieldnames                = gi_header.

In this gi_sheet_row contains proper data but when i export this to excel few fields for example field A which has value 0.056MM (32M") shows in excel 0.056#M (32#"). Now i am confused why so. is this due to FM. I am not sure. Please help.

Regards,

Ashish
