Play 1.x has a nice module that allows you to create Excel sheets. The new Play 2.x however lacks this capability. Or atleast is not very evident. While I found most of the information by searching the net, I thought it may help someone to just have quick start notes here.
I use Apache POI to generate Excel. I also wanted to create .xlsx rather than a plain .xls.
Add the following to your Build.scala (under APP_HOME/project)
val apache_poi = "org.apache.poi" % "poi" % "3.8" val apache_poi_ooxml = "org.apache.poi" % "poi-ooxml" % "3.8" val appDependencies = Seq( ... apache_poi, apache_poi_ooxml )
Actually, you don't need ooxml if you only want to create a plain xls (and not a xlsx).
Now start the Play console ('play') and execute 'run'. This will resolve the dependencies and get you the requisite libraries.
Now generate a excel:
import java.io.File import java.io.FileOutputStream import org.apache.poi.xssf.usermodel._ val file = new File("mydata.xlsx") val fileOut = new FileOutputStream(file); val wb = new XSSFWorkbook val sheet = wb.createSheet("Sheet1") var rNum = 0 var row = sheet.createRow(rNum) var cNum = 0 val cell = row.createCell(cNum) cell.setCellValue("My Cell Value") wb.write(fileOut); fileOut.close();
All done! Now, in your controller action, add the following:
Ok.sendFile(content = file, fileName = _ => "mydata.xlsx")
