During a DataSource Loop, the file only writes it to one line when I have multiple.
#JXL API EXAMPLE JAVA UPDATE#

#JXL API EXAMPLE JAVA CODE#
Here is some sample code that I found that works for me.įileInputStream fsIP= new FileInputStream(new File("C:/FileLocation/Excel.xls")) //Read the spreadsheet that needs to be updated When I was doing this with jxl, the whole file would overwrite any data that was in the file and wouldn't output my desired results. The reason this happens is because the system locks the first while. With POI, in order to update get your desired results (at least from what I'm seeing) you would have to upload the file you want to update and create a copy of the file. It's similar to jxl but has more support and is constantly updated. There have been some threads in the past but they either don't explain how it was accomplished or any links relating to the post are broken.įirst I switched to Apache POI. Make Sure the previous data on the worksheet does not erase. Write New Data onto the same Excel worksheet in a different Row.ģ. Open the excel worksheet with Groovy using jxl.Ģ. WorkSheet.addCell(new (13,0,"Another one for the Road")) ġ. WorkSheet.addCell(new (11,0,"Password2")) WorkSheet.addCell(new (10,0,"User Name")) SheetSettings sh = workSheet.getSettings() WorkSheet = workbook.createSheet("Test Report" ,3) WritableWorkbook workbookCopy= Workbook.createWorkbook(new File("C:/FileLocation/NewExcelFile"), workbook) WritableWorkbook workbook = Workbook.getWorkbook(new File("C:/FileLocation/ExcelFile.xls")) WorkbookSettings ws = new WorkbookSettings() I am working using the following code example but I am unable to get it to work.
