+### How to Generate CSV from XLSX
+
+```sh
+libreoffice --convert-to "csv:Text - txt - csv (StarCalc):44,34,UTF8,,,,false,true,true,false,false,1" --out-dir /home/user /home/user/abc.xlsx
+```
+
+This command will generate `abc-Sheet1.csv` under `/home/user`. The last `1` in the conversion options indicates the sheet number (starting from 1) to export. Detailed usage should be referred to at [CSV Filter Options](https://help.libreoffice.org/latest/ro/text/shared/guide/csv_params.html).
