I change name tags to Spanish?

  
Hello,

Good morning I have a question I explain . I have my entity defined in English and need to export a report to excel with certain attributes when viewing the report excel name headers are obviously in English and Spanish I can change them without changing my entities? I saw that there is an option that says Label if I put him there to Spanish does not work as it continues to export in groin.

Please help!
