Create new java project in eclipse with auto generated main function. Read Excel File. To read an excel file, Apache POI provides certain easy to use APIs. In below sample code we use different classes from POI library to read content of cell from excel file. This is for quick reference. HSSFSheet. import org. HSSFWorkbook. File. Input. Stream file new File. Input. Streamnew FileC test. Get the workbook instance for XLS file. HSSFWorkbook workbook new HSSFWorkbookfile. Get first sheet from the workbook. HSSFSheet sheet workbook. Sheet. At0. Get iterator to all the rows in current sheet. Iteratorlt Row row. Iterator sheet. Get iterator to all cells of current row. Iteratorlt Cell cell. Iterator row. cell. Iterator. Notice how each class in POI library starts with HSSF prefix HSSFWorkbook, HSSFSheet etc. HSSF stands for Horrible Spread. Sheet Format Im not kidding. It really is. Similar to HSSF, POI has different prefix for other file formats too HSSF Horrible Spread. Sheet Format reads and writes Microsoft Excel XLS format files. XSSF XML Spread. Sheet Format reads and writes Office Open XML XLSX format files. HPSF Horrible Property Set Format reads Document Summary information from Microsoft Office files.

Working with. xlsx files. The classes we used in above code snippet, HSSFWorkbook and HSSFSheet works for. In order to work with newer xls format viz. POI classes like import org.

XSSFWorkbook workbook new XSSFWorkbook file. Get first sheet from the workbook. XSSFSheet sheet workbook. Sheet. At0. Get iterator to all the rows in current sheet. Iteratorlt Row row. Iterator sheet. Get iterator to all cells of current row. Iteratorlt Cell cell. Iterator row. cell. Iterator. Use XSSFWorkbook and XSSFSheet class in all of the below examples in order to make them work with. Consider a sample excel file test. We will read above xls file using Apache POI and prints the data. File. Input. Stream file new File. Input. Streamnew FileC test. Get the workbook instance for XLS file. HSSFWorkbook workbook new HSSFWorkbookfile. Get first sheet from the workbook. HSSFSheet sheet workbook. Sheet. At0. Iterate through each rows from first sheet. Iteratorlt Row row. Iterator sheet. Iterator. Next. Row row row. Iterator. For each row, iterate through each columns. Iteratorlt Cell cell. Iterator row. cell. Iterator. whilecell. Iterator. has. Next. Cell cell cell. Iterator. Cell. Type. case Cell. CELLTYPEBOOLEAN.

File. Output. Stream out. File. Output. Streamnew FileC test. File. Not. Found. Exception e. e. Stack. Trace. catch IOException e. Stack. Trace. The above code is self explanatory. It read the sheet from workbook and iterate through each row and cell to print its values. Just note how we use different methods like get. Boolean. Cell. Value, get. Numeric. Cell. Value etc to read cell value. We Got Married Season 3 Eng Sub here. Before reading a cell content, we need to first determine its type using method cell. Cell. Type and then call appropriate method to read content. Output Emp IdNameSalary. John2. 00. 00. 00. Dean4. 20. 00. 0. Sam2. 80. 00. 0. Cass6. 00. 00. 00. Create New Excel File. Let us create a new excel file and write data in it. Following is the API which we will use for this purpose. HSSFSheet. import org. HSSFWorkbook. HSSFWorkbook workbook new HSSFWorkbook. HSSFSheet sheet workbook. SheetSample sheet. Create a new row in current sheet. Row row sheet. create. Row0. Create a new cell in current row. Cell cell row. create. Cell0. Set value to new value.
