Set file cell * .CSV as merged

Is it possible to have a particular cell merged into a generated * .csv file? I'm asking because I'm generating a * .csv file where the user should only make a Ctrl + C \ Ctrl + v in the content and paste it into a standard worksheet, but this default worksheet has the cell as merged where the content will be pasted and I do not I can modify this in the default worksheet so for this reason the need.

import java.nio.charset.StandardCharsets;
import java.util.logging.Logger;
Logger logger= Logger.getLogger("org.bonitasoft");

logger.info(suprimentosDevolvidos.toString())

BufferedWriter strW = new BufferedWriter(new OutputStreamWriter(new FileOutputStream("C:\TESTE\suprimentos.csv"), StandardCharsets.ISO_8859_1));

strW.write("QUANTIDADE TOTAL LOTE: "+quantidadeTotalLote.toString()+"\n")
strW.write(suprimentosDevolvidos.toString())
strW.close();
