Convert Excel to PDF Java Servlet Example

In this tutorial, we will provide a Java Servlet, that will accept a user uploaded Microsoft Excel document, and convert the Excel sheet data into a table in a PDF document. We will also demonstrate the ability to transform both XLS and XLSX extension files to PDF through the servlet. Some high level notes about this servlet are given below:

XLS to PDF Servlet – Notes

  • The servlet can accept both XLS and XLSX files as input.
  • The user will specify what type of file is uploaded.
  • Apache POI v3.8 would be used to read the user uploaded file.
  • iText 5.3.4 would be used to convert the uploaded file to PDF document.
  • The servlet will be hosted in Apache TomCat 6.0.36
  • apache-commons-fileupload-1.2.2 and apache-commons-io-2.4 will be used to convert the user uploaded file to InputStream.
  • By default we will assume the excel data is located in the first sheet in columns A and B. Though, this can be sent as an input the servlet if required.
I will not be covering the steps to configure the servlet in Apache TomCat. You can use this tutorial as a reference if you want to setup Apache to work with the servlet.
