Update cell’s value using different setCellValue methods. Open excel file in input mode (inputstream). ( "Excel written successfully.") įileInputStream file = new FileInputStream( new File( "C:\\update.xls")) Ĭell.setCellValue(cell.getNumericCellValue() * 2) įileOutputStream outFile = new FileOutputStream( new File( "C:\\update.xls")) HSSFSheet sheet = workbook.createSheet( "Sample sheet") HSSFWorkbook workbook = new HSSFWorkbook() Before reading a cell content, we need to first determine its type using method cell.getCellType() and then call appropriate method to read content. Just note how we use different methods like getBooleanCellValue, getNumericCellValue etc to read cell value. It read the sheet from workbook and iterate through each row and cell to print its values. New FileOutputStream( new File( "C:\\test.xls")) Iterator cellIterator = row.cellIterator() For each row, iterate through each columns Iterate through each rows from first sheet xlsx, you need to see newer POI classes like: In order to work with newer xls format viz. #JAVA JXL HASNEXT CODE#
The classes we used in above code snippet, HSSFWorkbook and HSSFSheet works for.
DDF (Dreadful Drawing Format) – a package for decoding the Microsoft Office Drawing format. HSMF (Horrible Stupid Mail Format) – a pure Java implementation for Microsoft Outlook MSG files. HPBF (Horrible PuBlisher Format) – a pure Java implementation for Microsoft Publisher files. HDGF (Horrible DiaGram Format) – an initial pure Java implementation for Microsoft Visio binary files. HSLF (Horrible Slide Layout Format) – a pure Java implementation for Microsoft PowerPoint files. HWPF (Horrible Word Processor Format) – aims to read and write Microsoft Word 97 (DOC) format files. HPSF (Horrible Property Set Format) – reads “Document Summary” information from Microsoft Office files. XSSF (XML SpreadSheet Format) – reads and writes Office Open XML (XLSX) format files. HSSF (Horrible SpreadSheet Format) – reads and writes Microsoft Excel (XLS) format files. Similar to HSSF, POI has different prefix for other file formats too: HSSF stands for Horrible SpreadSheet Format! I’m not kidding. Notice how each class in POI library starts with HSSF prefix! e.g. Iterator cellIterator = row.cellIterator() Code language: Java ( java ) Get iterator to all cells of current row Get iterator to all the rows in current sheet HSSFSheet sheet = workbook.getSheetAt( 0) 
HSSFWorkbook workbook = new HSSFWorkbook(file) Import .usermodel.HSSFWorkbook įileInputStream file = new FileInputStream( new File( "C:\\test.xls"))
