To replace ms word merge-fields with values with apache-poi both in paragraphs and tables with multiple columns.
As docx4j provides the function to replace merge-fields, is there any equivalent function by apache poi. Since I am using some custom tags in Docx file, reading the file in docx4j is ignoring custom tags(xml format "w:xyz").

It doesn't.
However there is an apache library for it, called Freemarker. It is a template engine and fully supports what are you looking for.

Is there a quick way you can template how to import XLSX files into Oracle directly?
I can use say apache POI to load it to a temporary java transfer object that gets sent to turn into jdbc/Sql in some fancy way. But it's slow as heck.
There is Sql Developer where you can import CSV. And other tools for CSV.
But what about xlsx spreadsheets from Microsoft Excel? Is there something that can import sheets, columns, formats, etc.?
One method would be to convert your Excel file from an xls file to a csv file and then you can use an Oracle external table.
I am working in building a project management tool,using MEAN(Mongodb,Expressjs,Angularjs,Nodejs) Stack.
I have a requirement in my project, where users will upload any kind of excel or csv format file and i need to parse each row from the file(excel|csv) and map it to my database model and save it has a mongodb document.I am trying to find an excel and csv parser library to accomplish my task.I also came accross xlsx, it looks good but it doesnt support reading csv files.It will be really helpful if any one could suggest a node.js library that can read all kinds of excel and csv file formats efficiently.Thanks in advance
At one point, I used Node CSV https://github.com/wdavidw/node-csv
to get the data inputted, it's really easy to use. Most of my users were fine with just having the CSV format option.....but you could combine the functionality of each library depending on the file type entered.....
I am working on creating orders/receipts for a certain client that provides the data using Excel. However, it is not a common Excel table format but an actual form to be printed. I am having issues with the data mapper since it cannot be parsed correctly.
Is there a way to get the data so I can transform it to a simple XML?
I'm thinking if I can just get the data by declaring which column/row.
I can suggest you to use a custom transformer using Apache POI from XLS to a simple java POJO, then you can get your XML using the object-to-xml-transformer.
apache POI: https://poi.apache.org/spreadsheet/quick-guide.html#Iterator
object-to-xml-transformer:

I am using the OpenXML SDK to manipulate my Excel files.
I'd like to store some custom XML data in the xlsx file (not in the sheet cells) in a way that survives a roundtrip through Excel.
Is it possible to do this with the CustomXmlPart class? Or some other class? If so, how?
CustomXmlParts are one way to do it. But here's another set of ways: How can I embed any file type into Microsoft Word using OpenXml 2.0 (Word/Excel = same concept)
