```
public XSSFWorkbook(XSSFWorkbookType workbookType)

    workbookType - The type of workbook to make (.xlsx or .xlsm).
  - XSSFWorkbook
```
public XSSFWorkbook(OPCPackage pkg)
             throws java.io.IOException
```
    Constructs a XSSFWorkbook object given a OpenXML4J Package object, see https://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 - If reading data from the package fails
    
    POIXMLException - a RuntimeException that can be caused by invalid OOXML data
    
    java.lang.RuntimeException - a number of other runtime exceptions can be thrown, especially if there are problems with the input format
  - 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 - If reading data from the stream fails
    
    POIXMLException - a RuntimeException that can be caused by invalid OOXML data
    
    java.lang.RuntimeException - a number of other runtime exceptions can be thrown, especially if there are problems with the input format
  - 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 - If reading data from the file fails
    
    InvalidFormatException - If the file has a format that cannot be read or if the file is corrupted
    
    POIXMLException - a RuntimeException that can be caused by invalid OOXML data
    
    java.lang.RuntimeException - a number of other runtime exceptions can be thrown, especially if there are problems with the input format
  - 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 - If reading data from the file fails
    
    POIXMLException - a RuntimeException that can be caused by invalid OOXML data
    
    java.lang.RuntimeException - a number of other runtime exceptions can be thrown, especially if there are problems with the input format
  - XSSFWorkbook
```
public XSSFWorkbook(PackagePart part)
             throws java.io.IOException
```
    Constructs a XSSFWorkbook object using Package Part.
    
    Parameters:
    
    part - package part
    
    Throws:
    
    java.io.IOException - If reading data from the Package Part fails

public XSSFSheet createSheet()
```

    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 (\)

    Returns the list of ExternalLinksTable object for this workbook
    The external links table specifies details of named ranges etc that are referenced from other workbooks, along with the last seen values of what they point to.
    
    Note that Excel uses index 0 for the current workbook, so the first External Links in a formula would be '[1]Foo' which corresponds to entry 0 in this list.
    
    Returns:
    
    the ExternalLinksTable list, which may be empty

  - 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:
