Created attachment 36688 [details] Empty external data from file Sequnce: 1) Using SXSSF to add data and generate excel file. 2) Using microsoft excel 'Data -> Get external data -> From file' shows no data in file, but they are 100% there. But if you open the file in excel and 'Save as' then 'Data -> Get external data -> From file' functionality work fine. Investigation shows that in sheet from 'Saved as' file dimension tag is <dimension ref="A1:E4"/> and in file that was generated with SXSSF dimension tag is <dimension ref="A1:E1"/>. I tried next code but didn't helped: sxssfWorkbook.getXSSFWorkbook.getSheet(sheet.getSheetName).getCTWorksheet.getDimension.setRef("A1:" + CellReference.convertNumToColString(nubmerOfCol) + contentLenght) fastWriteWb.write(fileOutputStream) Is there any hot-fix for this?
