How to set Author name to excel file using poi

Question

I\'m creating an excel (.xlsx) file using poi (java). After I create the excel file I see the excel file Author as \"Apache POI\". Is there any way to change that?

Answer 1

Not a direct answer but in case anyone needs to do this in NPOI (the .NET port of POI) here is the extension method I came up with ... it's basically what Olivier suggested - only implemented in C#:

/// <summary>
/// Sets the author of this workbook.
/// </summary>
/// <param name="workbook"></param>
/// <param name="author"></param>
public static void SetAuthor(this IWorkbook workbook, string author)
{
    if (workbook is NPOI.XSSF.UserModel.XSSFWorkbook)
    {
        var xssfWorkbook = workbook as NPOI.XSSF.UserModel.XSSFWorkbook;
        var xmlProps = xssfWorkbook.GetProperties();
        var coreProps = xmlProps.CoreProperties;
        coreProps.Creator = author;
        return;
    }

    if (workbook is NPOI.HSSF.UserModel.HSSFWorkbook)
    {
        var hssfWorkbook = workbook as NPOI.HSSF.UserModel.HSSFWorkbook;
        var summaryInfo = hssfWorkbook.SummaryInformation;

        if (summaryInfo != null)
        {
            summaryInfo.Author = author;
            return;
        }

        var newDocInfo = NPOI.HPSF.PropertySetFactory.CreateDocumentSummaryInformation();

        var newInfo = NPOI.HPSF.PropertySetFactory.CreateSummaryInformation();
        newInfo.Author = author;

        hssfWorkbook.DocumentSummaryInformation = newDocInfo;
        hssfWorkbook.SummaryInformation = newInfo;

        return;
    }
}

Answer 2

It's pretty straightforward:

HSSF:

SummaryInformation summaryInfo = workbook.getSummaryInformation();
summaryInfo.setAuthor(author);

XSSF:

POIXMLProperties xmlProps = workbook.getProperties();    
POIXMLProperties.CoreProperties coreProps =  xmlProps.getCoreProperties();
coreProps.setCreator(author);

Have fun :)
