I need to create cell comments for existing excel file by extracting the xlsx file and using raw XML file.
Is it possible to do it in java without using Apache poi library?
Well I don't know much about excel but I found this website that might help you.

I want to read and append a .xlsm file in java. I dont have any idea on how to do it.
Do i need to download any jar file to work with it?
All the search result provides a solution which uses apache poi(I did not get what it is). I dont use any IDE. Using simple FileReader and other logic can't I work with this type of file?
Please give me a clear idea on what is a .xlsm file and how to work with it using java.
"XLSM is a Microsoft Excel macro-enabled spreadsheet that contains worksheets of cells arranged by rows and columns and embedded macros programmed in the Visual Basic for Applications language. XLSM files are like XLSX files, but with macros enabled. They can be opened with Excel 2007 or later, or by previous versions of Excel with Open XML component support."
You can read and write to the file using Apache poi.
Take a look at the following SO Posts
write to xlsm (Excel 2007) using apache poi
Read data from read only xlsm file using Java Apache POI
The Apache POI documentation is located at
https://poi.apache.org/
Does anyone know if I can use something like Apache POI to convert an Excel file into CSV file in Java without application to parse into it?
Well, there needs to be some application, but you don't have to write it yourself.
I think there is no such ready-made tool included in POI itself, but other people have made such things and you can probably (disclaimer: I have not tried any) use them, for example
https://github.com/anjlab/excel2csv-java
http://code.google.com/p/excel2csv/
Note that this is bound to work only for very simple Excel files, as the Excel workbook format supports a lot of stuff that cannot be expressed in CSV.
Does anyone know if it's possible to save an Excel Spreadsheet as a jpg using java? Currently, I am reading and manipulating Excel Spreadsheets in java using Apache POI. It's working great for everything else, but I haven't been able to find an answer to this question in their documentation or online.
There are some commercial libs to do so, another solution would be to use Apache POI to render your Excel as HTML and then convert this to an image utilizing a lib like this java-html2image
I need to create spreadsheet in various file format: .xls, .xlsx, .ods, csv. I want to know how can I achieve this in Java and about available open source API.
I found some API for .xls, .xlsx but not .ods. Any information will be very helpful.
Thanks and Regards.
Have you tried the OdfToolkit? I haven't used it but it sounds like something you need.
For pdf generation you can use apache fop and altova stylevision to generate xsl-fo files. For xls - there is apache poi and jxls for templating.
For .ods I am using Simple ODF.
Update
Simple ODF is moved to Apache. New link is here.
I need code in java for Excel to XML conversion.
where Excel sheet will be used as the input file and XML file as the output file.we have to read the Excel file Row and column wise and than write that data to XMl file.

Have a look at Apache POI. I'm sure there are some examples there.
This may not be the answer you were looking for, but Excel already has built-in support for XML. If you are using Excel 2007, you will need to enable the Developer tab on the ribbon. From there you can import and export XML schemas and files.
To enable the developer tab:
Click the Microsoft button...
Click Excel Options
Check "Show Developer Tab in the Ribbon"
You will need to create a map by either importing an example XML file that is in the same format as the one you'd like to export, or you can click Source and use a schema (XSD) file.
From there, you just need to map the elements in your XML Map to the data in your sheet, then export the data to an XML file.
I did a "Read Excel into a DefaultTableModel" in about 20 lines with the JExcel API. It was very nice and simple to use.
JExcel is another option, although I think it has less features and doesn't support the latest excel format like the Apache POI does.
I have done conversion of Excel(xlsx) to xml in Java recently. I assumed each row in excel as a single object here. Here are the steps I followed:-
Read Excel file using Apache POI
Created a xsd file and generated corresponding classes
Read each row created, created corresponding objects and initilaized values using the generated getter/setter methods in the classes
Added the objects to an arraylist which holds only objects the same type
Using Jaxb Marshelled the arraylist object to an output file
