what are the relevant differences between this libs ? also can tell me anyone about the license of this products ?
i need to generate large files .xlsx files. Until now i used jxl lib in for .xls with a a formated header using jxl.write.WritableCellFormat.
1) JXL is now JExcel.
2) You can get all list of differences between JExcel and Apache POI here
3) Both are free.
4)You should use Apache POI because JExcel does not support .xlsx format.
Difference between JXL and POI is that Java JXL does not support the Excel 2007+ ".xlsx" format; it only supports ".xls" format.
Apache POI supports both with a common design.

I've read it stated on multiple SO questions that Apache POI 3.16-beta3 has read-only support for xlsb files.
I am using poi 3.17 and cannot find any documentation or examples of this feature. The best I can find is an example of extracting raw text only via XSSFBEventBasedExcelExtractor, but this appears to be quite old (2010?) and I am unsure if this is the referenced capability.
Is there any documentation or examples of using poi to read xlsb files with the read-only parsing alluded to in the comments of this question: Exception reading XLSB File Apache POI java.io.CharConversionException and in an answer to this: Reading data from .xlsb in Clojure by Tim Allison ?
The functionality that Tim was referring to is actually XSSFBEventBasedExcelExtractor, and it was added in Apache POI 3.16. It can be used to extract text-content from the file.
There is currently no functionality to fully read the file content, though.
See also the JavaDoc for this class.
I ask for help with the next task. It is planned to use Apache FOP to generate various reports, but the question arose whether FOP can generate any format that could be opened in Excel. It is desirable with an example. Thank you in advance.
Kindly let me know your input file format?. If your file is Xml format or .fo format we can extract the excel file using the input file by using with combination apache poi. we can extract the output files in XLS or XLSX format . Else combine open office XML to apache fop code. where it takes alot of effort.
I am using Apache POI to write and read excel files,my poi version is 3.9,but now I faced a problem and do not find a good solution to solve it.
First I am use poi to write some datas to the excel table and will use DataValidation to add some prompt information in the table header,as the picture shown below:
The value in the cell is ABSInterention,and the prompt title is wrxuoh.After the excel generated successfully,other users will add some modification to the data cell and I need to read and parse the excel file and I want to get the prompt value wrxuoh again.So my question is:
When I read excel file using POI3.9,how can I get all the DataValidations for the current sheet?
I am using HSSFWorkbook and HSSFSheet.I found there is a method called getDataValidations in the POI Sheet,but I can not find this method in my poi3.9 jar file and also can not find it in the POI3.9 javadoc.
any help would be grateful!
Promoting a comment to an answer - you can't
That functionality was added to Apache POI after the 3.9 release you mention in your question
As per the Apache POI Changelog, you need to upgrade to at least POI 3.11 beta 3 to use that feature. 3.11 final, when it comes out shortly, will be the first stable release to include it
I have 65000 data for getting from DB into excel.But PF DataExporter component is not writing big data into the excel.What can I use for this process?Is there a library for this process?
You can use:
Apache POI Some examples - Quick guide very easy to use and excellent simple examples
Jasper reports Just link - needs some time to figure it out
If you need just one excel export, use Apache POI.
If you have a lot of reports, i would recommend you to use Jasper reports because you can have option to export it to PDF, Excel, Word and other formats.
Good luck!
With M$ Excel 2013 there are 2 variants of XLSX, the "Transitional" which M$ supported with XLSX in Excel 2010, and "Strict" = OOXML. Is POI able to read and write the latter? If so, from which version of POI?
Yes, and POI 3.5 (though you'd be strongly advised to use 3.9, or wait about a week for a 3.10 beta)
POI uses the official ISO XML schema files to process the XML files, so by default works with the strict (official) form. There's not that much different between the two, but where there is such a difference that matters, POI will have code to munge the low level XML skipping what the schema would normally say.
No, Apache POI does not support Open XML Strict as of this date.
