```
public XSSFWorkbook(XSSFWorkbookType workbookType)

```
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

```
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

```
    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:

```
    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

  - 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

```
public void removeSheetAt(int index)
```

  - getExternalLinksTable
```
@Internal

    Adds the External Link Table part and relations required to allow formulas referencing the specified external workbook to be added to this one. Allows formulas such as "[MyOtherWorkbook.xlsx]Sheet3!$A$5" to be added to the file, for workbooks not already linked / referenced.

  - setForceFormulaRecalculation
```
public void setForceFormulaRecalculation(boolean value)
```
    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:
