 ```Java
-CellsApi cellsApi = new CellsApi(CellsApiUtil.GetClientId(),CellsApiUtil.GetClientSecret())
-String name = BOOK1;
-String sheetName = SHEET1;
-Integer position = 1;
-String sheettype ="VB";
-String folder = TEMPFOLDER;
-cellsApi.uploadFile(folder +"\\" + filename, new File(sourceFolder + filename), null);
