```
public XSSFWorkbook()
```
    Create a new SpreadsheetML workbook.
  - XSSFWorkbook
```
public XSSFWorkbook(OPCPackage pkg)
             throws java.io.IOException
```
    Constructs a XSSFWorkbook object given a OpenXML4J Package object, see http://poi.apache.org/oxml4j/.
    Once you have finished working with the Workbook, you should close the package by calling either close() or OPCPackage.close(), to avoid leaving file handles open.
    Creating a XSSFWorkbook from a file-backed OPC Package has a lower memory footprint than an InputStream backed one.
    
    Parameters:
    
    pkg - the OpenXML4J OPC Package object.
    
    Throws:
    
    java.io.IOException
  - XSSFWorkbook
```
public XSSFWorkbook(java.io.InputStream is)
             throws java.io.IOException
```
    Constructs a XSSFWorkbook object, by buffering the whole stream into memory and then opening an OPCPackage object for it.
    Using an InputStream requires more memory than using a File, so if a File is available then you should instead do something like
```
       OPCPackage pkg = OPCPackage.open(path);
       XSSFWorkbook wb = new XSSFWorkbook(pkg);
       // work with the wb object
       ......
       pkg.close(); // gracefully closes the underlying zip file
   
```
    Throws:
    
    java.io.IOException
  - XSSFWorkbook
```
public XSSFWorkbook(java.io.File file)
             throws java.io.IOException,
                    InvalidFormatException
```
    Constructs a XSSFWorkbook object from a given file.
    Once you have finished working with the Workbook, you should close the package by calling close(), to avoid leaving file handles open.
    Opening a XSSFWorkbook from a file has a lower memory footprint than opening from an InputStream
    
    Parameters:
    
    file - the file to open
    
    Throws:
    
    java.io.IOException
    
    InvalidFormatException
  - XSSFWorkbook
```
public XSSFWorkbook(java.lang.String path)
             throws java.io.IOException
```
    Constructs a XSSFWorkbook object given a file name.
    Once you have finished working with the Workbook, you should close the package by calling close(), to avoid leaving file handles open.
    Opening a XSSFWorkbook from a file has a lower memory footprint than opening from an InputStream
    
    Parameters:
    
    path - the file name.
    
    Throws:
    
    java.io.IOException

```
    Description copied from interface: Workbook

  - createSheet
```
public XSSFSheet createSheet()
```
    Create an XSSFSheet for this workbook, adds it to the sheets and returns the high level representation. Use this to create new sheets.
    
    Specified by:
    
    createSheet in interface Workbook
    
    Returns:
    
    XSSFSheet representing the new sheet.
  - createSheet
```
public XSSFSheet createSheet(java.lang.String sheetname)
```
    Create a new sheet for this Workbook and return the high level representation. Use this to create new sheets.
    Note that Excel allows sheet names up to 31 chars in length but other applications (such as OpenOffice) allow more. Some versions of Excel crash with names longer than 31 chars, others - truncate such names to 31 character.
    
    POI's SpreadsheetAPI silently truncates the input argument to 31 characters. Example:
```
     Sheet sheet = workbook.createSheet("My very long sheet name which is longer than 31 chars"); // will be truncated
     assert 31 == sheet.getSheetName().length();
     assert "My very long sheet name which i" == sheet.getSheetName();
     
```
    Except the 31-character constraint, Excel applies some other rules:
    Sheet name MUST be unique in the workbook and MUST NOT contain the any of the following characters:
    - 0x0000
    - 0x0003
    - colon (:)
    - backslash (\)
    - asterisk (*)
    - question mark (?)
    - forward slash (/)
    - opening square bracket ([)
    - closing square bracket (])
    The string MUST NOT begin or end with the single quote (') character.
    
    See WorkbookUtil.createSafeSheetName(String nameProposal) for a safe way to create valid names
    Specified by:
    
    createSheet in interface Workbook
    
    Parameters:
    
    sheetname - sheetname to set for the sheet.
    
    Returns:
    
    Sheet representing the new sheet.
    
    Throws:
    
    java.lang.IllegalArgumentException - if the name is null or invalid or workbook already contains a sheet with this name
    
    See Also:
    
    WorkbookUtil.createSafeSheetName(String nameProposal)

    removePrintArea in interface Workbook
    
    Parameters:
    
    sheetIndex - 0-based sheet index (0 = First Sheet)
  - removeSheetAt
```
public void removeSheetAt(int index)
```
    Removes sheet at the given index.
    Care must be taken if the removed sheet is the currently active or only selected sheet in the workbook. There are a few situations when Excel must have a selection and/or active sheet. (For example when printing - see Bug 40414).
    This method makes sure that if the removed sheet was active, another sheet will become active in its place. Furthermore, if the removed sheet was the only selected sheet, another sheet will become selected. The newly active/selected sheet will have the same index, or one less if the removed sheet was the last in the workbook.
    
    Specified by:

    Whether the application shall perform a full recalculation when the workbook is opened.
    Typically you want to force formula recalculation when you modify cell formulas or values of a workbook previously created by Excel. When set to true, this flag will tell Excel that it needs to recalculate all formulas in the workbook the next time the file is opened.
    
    Note, that recalculation updates cached formula results and, thus, modifies the workbook. Depending on the version, Excel may prompt you with "Do you want to save the changes in filename?" on close.
    
    Specified by:
    
    setForceFormulaRecalculation in interface Workbook
    
    Parameters:
