Then I processed by each sheet. So that the error message did not displayed and therefore, problem was solved.
I really recommend when transating the Excel file exspecially huge one, please try to do it on individual sheet.
This is my answer for my problem.
I support this idea. If the Excel file has many worksheets, Trados or SDL consumes a badly a long time to convert or save the target file. I often thought that the program crashed but it did not.
